monohull vs trimaran

Why Choose a Trimaran over a Monohull?

Why choose a trimaran over a monohull:.

Corsair Trimarans provide safe sailing excitement for the whole family

The first item on this list might surprise you.  But trimarans are exceedingly safe – in fact many, including all of the Corsair trimarans , are virtually unsinkable.  They’re foam cored, and relative to the displacement of the boat, the buoyancy of the materials is very high. Even were a Corsair to be fairly well destroyed (think passenger ferry) the remaining debris would remain at the surface providing something to cling onto. But there are some other interesting stats as well.  Kids love trimarans – the nets make for great fun.  And were they to fall into the water its reassuring that there are so many places for a person (or child) overboard to grab onto – see the net lines and the beams themselves in the picture to the right.  There are also good places at the main transom to haul out a wet, heavy, miniature crewmember.

No gimmicks.  Trimarans simply deliver stunning speed without foils, wings or electronic aids. Speed might have slipped from number 1 factor to number 2 in recent years – and given the advent of foiling monohulls you might think that’s fitting.  But consider the costs involved in foiling monohulls and you’ll quickly find that Corsair trimarans have a far greater dollar-to-knot ratio. Operationally, trimarans are now seen as almost conventional in high-speed terms.  So you can clock up 20-knot plus speeds with a boat that has a 35-year track record of success and safety, and without the need for professional crew.

For a trimaran, this counts as “heeling”

While you, the reader are no doubt the hardiest of sailors, there’s also no doubt that not everybody you sail with will be! Corsair trimarans, and most others, have a max heel angle of 12-14 degrees depending on the model.  That’s “flat sailing” in monohull terms.  And it means that rudders and daggerboards keep a reassuring grip and the speed therefore feels more effortless on the helm.  That surefootedness transfers over to your crew – they’ll detect the confidence in the boat and the skipper.

Small Marina Footprint

Fold up and take only a small marina berth or land space

To achieve anything like the speed, and just a bit of the stability and comfort underway, you’d need a relatively large monohull by comparison.  But due to the folding mechanism, a Corsair trimaran keeps a very modest marina footprint.   Better still, they can be lifted (when folded) and are therefore easy to keep ashore.  Want to keep your boat in the water but worried about growth on the floats/pontoons?  Anti-fouling wraps from 3M are available from Corsair dealers – remarkably long lived, these are easily replaceable, and maintain a very quick surface.  Boat bags, which keep growth away from the floats and main hull, are available for mooring and marina use.

Above Deck Space

Anyone with children will immediately identify with this one – Corsairs are fantastic for their wingnet and bownet space.  When unfolded, the huge beam provides pound-for-pound the best boating platform around.  The nets are often used as sleeping hammocks in extremely hot climates – not just for an afternoon nap, but actually during the night.  And most trimarans can be fitted with a bimini, sail shade, or canopee when the sun is strong.

Trimarans are Synonymous with Trailerability

The new Corsair 880 Trimaran will be the Ultimate Trailer-sailer

In the next article, we’re taking a deeper look at trailering trimarans through an interview with the undisputed supremo in trailering tri’s – our very own dealer Werner Stolz from Germany.  Trailerability is absolutely central to creating a new holiday experience every year, and for the racers it opens up a whole new world of high speed multihull regattas.  That’s why Corsair trimarans are built light – of course it improves your sailing speed, but it also keeps your trailering weight down and reduce road risk.  And that’s why the floats fold underneath – so your boat doesn’t get longer on the trailer when folded.  For those who don’t want to commit to the same sailing grounds every year there’s no better solution than a Corsair folding trimaran.

We get these questions all the time: Are catamarans and trimarans really superior to monohulls? In what ways? Does it matter to me? What are the key differences between catamarans and trimarans? Here are the basics:

Reefing: Sailing catamarans and, to a lesser extent, trimarans too, require vigilance when it comes to reefing. Since they don’t heel much, almost all additional wind force is converted to load on the rig. That’s where the speed comes from. But since the pressure on the sails quadruples as the wind speed doubles, crews must keep an eye on the weather and reef in good time to keep the boat safe and sailing flat. In fact, a properly reefed cat or tri will sail faster too, in freshening breezes. All manufacturers supply written guidelines denoting apparent wind speeds that require additional reefing.

Safety – Unsinkability There are many aspects to safety where catamarans and trimarans shine. Often overlooked is the safety margin introduced with level sailing (see above). It is much easier to keep crew aboard in rough weather when the boat stays level and is pitching less. Large cockpit spaces keep crew well away from the lifelines as well.

The speed of a multihull is another safety factor, as with decent weather information it’s relatively easy to sail around severe weather systems before they can bear down on you. Should something go horribly awry, and the boat get flipped (VERY rare – see below), the lack of ballast, and additional positive flotation, means that nearly every catamaran and trimaran produced in the last few decades will remain on the surface of the water, rightside up or not, until a rescue can be made. Nearly all cruising cats and tris have a substantial amount of reserve buoyancy, in the form of closed-cell foam, stashed in the nooks and crannies of the boat. Because of this, most could literally be cut into pieces and all pieces would still float. This makes fire your biggest safety concern aboard a cat. And the anchor windlass, but that’s a story for another day.

Can my catamaran or trimaran flip over? This is theoretically possible, and has happened in very rare heavy-weather situations when EVERY vessel is in distress. It takes very high winds, too much sail (see reefing, above), and large breaking waves to flip a modern cruising cat or tri. Multihull sailors find it reassuring to know that their cat or tri will remain on the surface, as a big liferaft and spotting target, while ballasted monohulls caught in the same situation are more likely to end up on the bottom of the sea, with their crew bobbing around (if they are lucky) in an inflatable liferaft.

Motoring Performance/Maneuverability Cruising catamarans and trimarans, with their easily driven hull forms and light weight, enjoy excellent fuel efficiency when compared to monohulls, and track very straight. Cats almost always have twin engines, set many feet apart, which allow for tremendous control in tight situations. In fact, the boat can be spun in place or crabbed sideways without any way on. Try that on a monohull. Prop walk is minimal or nonexistent as well, and the redundancy of a second engine is appreciated should a mechanical issue arise underway. Nearly all trimarans have just one engine, so the differences there are slight.

Monohull vs Trimaran

Which is better, a monohull or trimaran.

Since we have recently made the switch from a monohull sailboat to our speedy trimaran, I thought I would shed some serious light, and weight, on the subject!

Let’s first recap our two comparison vessels which we have over 10k miles of sailing with each:

39ft Amel Sharki - ‘Panda’

The Amel Sharki is very much defined as a ‘classic’ monohull in terms of her construction, design brief, and sailplan. She was designed ideally for a couple to sail around the world comfortably . Built in 1980 by Amel in LaRochelle, France, Panda was hull number #12 of this really cool Sharki range. With an integral keel, skeg hung rudder, she was outstandingly sturdy. The glass was not cored (except for the decks), and very thick in places (we measured over 1.5” at the centerline for the depth-sounder hole). The sailplan was easily managed being ketch rigged, thus essentially reducing the mainsail size in two smaller sails.

45ft Neel Trimaran - ‘Panda ROSSO’

A unique design philosophy in the world of multihulls, introduced by Eric Bruneel, this range of trimarans has a bridge deck layout. Unlike your typical trimaran, which is essentially a much narrower monohull with amas (the out-rigger things!), our Neel boasts a high and wide surface area above the main hull, allowing for a comfortable living space. The design brief is similar, but with a nod to performance. The hull is fully cored with PVC foam, sandwiched between two layers of glass which the resin is infused via a vacuum bagging process to eliminate any extra resin. The rudder is a free-standing spade, small integral keel in front of a modern Volvo saildrive. The mast is a fractional variety with aft sweeping upper and lower shrouds, twin forestays with furling headsails, and single diamond spreaders.

Ok, you have given me a lot of information, but which is better?

It is difficult to give an ‘overall’ rating, so lets break it down point-by-point:

Stability: Inherently, a multihull is more stable due to its width. While sailing, a trimaran does heal a little, somewhere in between a monohull and a catamaran. While at anchor, our trimaran does rock a little, more so than a catamaran, but less than a monohull.

Performance: Since a multihull is inherently stable in it’s design due to its high ‘form stability’, it thus lacks a deep keel with ballast and it’s weight is dramatically reduced! For example, our Amel weighed in at 12 tons, whereas our Neel is just over 7.5 tons, for a much larger boat. Additionally, the hull shape of a multihull allows for long, slender, profiles which essentially lack a ‘hull speed.’ Thus, we are no longer limited to around 7-8 kts for our waterline length. Instead, we can push into the low teens, and have topped out with a long Atlantic Ocean surf of 19.7kts!

Maneuverability: Our trimaran has one engine, and one bow-thruster, essentially like a mono without a keel to turn around. Thus, her ability to maneuver in the harbor is tough to say the least! With so much windage, she gets blown sideways easily, and her high-tech, low-drag, folding propeller lacks serious thrust in reverse and has almost no noticeable prop-walk. Our Amel had no bow thruster, but a good amount of prop-walk and I found it easier to dock than the Neel. However, for our style of sailing, we rarely visit a dock, maybe once every 2-3 months so we find the difficulty worth the trade-offs.

Safety: This is a huge topic with lots of sub-topics, but lets start with impacts. The foam core is probably less resilient to a hard grounding compared to the Amel. However, in a serious water ingress situation, I feel the Neel would fair much better having three separate hulls which are highly compartmentalized. I have heard of one case of a Neel’s central hull flooding and the owner sailing another 200nm to port as the ama’s supported the extra flotation requirement.

Costs: Multihulls are a clear looser in this catagory. They are generally larger, thus more systems, bigger sails, taller rig, and simply more cost. Those costs continue through ownership with additional maintenance and increased docking / mooring fees. Looking to haul-out? Think twice, or three times! Our Neel 45 is 28.5ft (8.6m) wide, which leaves us to only a handful of lifts and trailers which can accommodate her beamy ways. A monohull wins on all fronts, especially when hauling out as facilities are generally built around this style of boat.

Sailing Pleasure: I just love the way a monohull sails. There is something sexy, like a ‘poetry in motion’ about their stride through the water. The feel through the helm, the heel during a gust, and the gate through a swell is un-matched by a monohull. But, what is the next best thing? A trimaran of course! On our Neel we also heel and have great helm feedback, which a typical catamaran lacks. Now the motion upwind can be described as bouncy, which is different than the Amel which was as smooth as you’ll get in a monohull. But, interestingly, due to the super narrow hulls, we almost don’t slow down when slicing through a wave-state. There is no pounding, no bridge deck slamming, just a clean slice through the sea!

Well, that was a lot MORE information, but hey, which is BETTER?

If we were to give an overall score, we would personally have to say our trimaran wins out over the monohull. In terms of sailing and passage-making, we find ourselves enjoying the extra speed. Especially running downwind, our Neel is stable and fast! And with that stability comes extra comfort aboard. We are noticeably less fatigued mile-by-mile than our monohull.

This probably didn’t really help you decide, but I hope it sparked some thoughts. With sailboats, there are ALWAYS compromises and in the end, it comes down to your personal preference including cruising style, budget, and accommodation needs, among a laundry list of desires.

Trimaran Sailboats: Pros and Cons

Sep 22, 2021

less than a min

Trimarans are boats in the multihull category. So let us give you a simple overview. A monohull has just one hull, a catamaran is a boat with two hulls, while a trimaran as the name itself suggests, has three hulls ( one central hull and two side ones that are smaller ).

There are many reasons why people prefer trimarans to other boats. These vessels are very easy to maneuver and quite light compared to catamarans or monohulls. They are often considered as an advanced form of the catamaran. The reason being, trimarans are faster than the average catamaran and obviously faster than monohulls. 

In addition, trimarans are much more stable than the alternative. The three hulls provide extra balance and lower resistance because even if there are three hulls in a trimaran, they are smaller and narrower. Lower resistance also leads to lower fuel consumption. 

Trimarans are very comfortable to sail in as the main hull is stabilized by the two outer hulls . 

Also, if you enjoy spending more time outdoors rather than indoors (which is usually the case for people who like sailing), trimarans offer more deck area that you can utilize. Whether for meditation, or social gatherings, this space offers plenty of breathtaking views and fresh air. 

Let’s not forget that trimarans have smaller gaps in between the hulls which makes them easier to build and therefore less expensive for the public to buy. 

This article however is titled trimarans pros and cons, so it is time to move into some less appealing characteristics of these vessels. 

While they offer plenty of deck space, the area below the main deck is limited, therefore you cannot have as many people on board as you would in a monohull or even a catamaran. 

In addition, trimarans are not appropriate for every type of activity. If you want to use it for recreational sailing then these boats will provide plenty of enjoyment. If your scope is to find something for the military or fishing, trimarans are not often the best choice. 

If you have your mind set on a specific trimaran, search it on TheBoatDB . Our extensive database includes features, pictures, specifications, and more useful information on a variety of boats. What is most interesting however is that you can also compare a couple of models side by side and decide which one is your favorite by getting all your facts straight.

Why You Want a Trimaran: Pros and Cons of a Trimaran

Three hulls are better than one!  That would be the adage of the trimaran.  It consists of one central hull with two smaller side hulls, called amas.  The average person conceives of the trimaran as something even more extreme than catamarans.  Lighter weight, higher speed, more specialized.  The opposite is actually true; trimarans fill an excellent transition role between monohulls and catamaran.  Recognize the potential applications by understanding the strengths and weakness of the trimaran hullform.

1.0 What Makes a Trimaran

When you seek trimarans, envision stability.  A conventional monohull must balance conflicting needs of resistance and stability.  You want a narrow skinny hull to reduce resistance (and fuel consumption).  But you need a wide hull to maintain vessel stability and keep the ship upright.  The trimaran separates these two design requirements.

In a trimaran, the central hull provides most of the ship buoyancy (90-95% usually).  It does this with a long, narrow hull.  And then the outer hulls, called amas, provide the stability.  This arrangement allows incredible flexibility in the hull design.  Due to the wide separation between hulls, it requires very little buoyancy in the amas to keep the trimaran stable.  That is why many trimarans barely have their amas in the water.  Compare the relative size of the amas vs the main hull in Figure 1‑1.  The amas are just there for stability.

2.0 Advantages

The trimaran offers several capabilities to bridge the gap between monohulls and catamarans:

• Excellent for high speed
• Moderate weight carrying capacity
• Good seakeeping capability
• Larger available deck area
• Moderate space below the main deck

Another advantage is the design of the cross deck (Figure 2‑1) between the main hull and amas.  On a catamaran, this cross deck bridges a large empty gap.  Large gaps add complexity to the engineering and require stronger structures.  We don’t like that.  Stronger structures mean more weight and higher costs.  But the trimaran’s cross deck is much smaller.  It requires less of a gap between hulls, and it does not extend for the entire ship length.  Longitudinal bending is less of a concern for the cross deck.  This greatly simplifies the design of that cross deck, giving us many advantages:

• Heavier loads can be carried on the cross deck
• Less structural weight required for the cross deck
• Deadweight coefficients closer to monohulls

The long length of the center hull also offers great advantages for seakeeping.  This length greatly reduces pitch motions in a wave, and the narrow center hull reduces chances of slamming.  To improve things even more, the side amas reduce roll motions.  They add stiffness to prevent large roll motions.  But they also act to reduce roll accelerations.  All together, trimarans make for gentle seakeeping.

The trimaran offers major advantages for damage survival.  The side amas provide excellent protection to the center hull, which military designers find especially useful.  But the cross deck also helps with damage survival by containing massive reserve buoyancy.  Imagine a damage situation where the ship sinks down to its cross deck.  On a monohull, that would be game over.  But on a trimaran, the cross deck suddenly becomes a barge, easily supporting the entire ship weight.  This reserve buoyancy provides extra peace of mind in yachting applications.

Speaking of peace of mind, let’s talk about a sudden loss of stability.  In catamarans, you lose stability once a single ama completely leaves the water.  Push a catamaran past that point, and stability is a losing battle.  A fact that scares many vessel operators.  Trimarans do not have this problem.  They get stability mainly from submerging the amas.  The center hull always stays in the water, and the leeward ama continues to submerge.  This creates a predictable increase in righting moment.  In normal cases, trimarans never experience the sudden loss of stability.

3.0 Disadvantages

The biggest disadvantage for trimarans is lack of experience.  There are few trimarans in military applications, and even less in commercial use.  That lack of exposure instills wariness in many operators.  I appreciate caution, but don’t let that stop you from realizing the benefits of a trimaran.

Trimarans do have a few genuine detractors.  Due to their complexity, they require some extra design effort.  The cross deck introduces a few extra ways to twist and bend the ship, and the engineers must check each of these extra scenarios.  Finite Element Analysis (FEA) is the ideal tool for this.

Don’t worry about the FEA bill.  You should expect a slight increase, but nothing huge.  FEA was already a part of the design process for normal monohulls.  Most ship designs already require FEA to consider global hull bending.  That means the hard part is already done.  Your engineer already had to build an FEA model of the hull.  With minimal effort, engineers can expand that model to account for the additional design scenarios of a trimaran.

Cost definitely factors into trimaran construction.  The cross deck and extra hulls do add extra steel to the design.  You have to pay for that extra steel as part of the build cost. (Figure 3‑1)  But don’t assume this drastically increases the total build cost.  Adding extra structure is far less expensive than adding extra machinery and power.

Consider the alternative to a trimaran:  an equivalent monohull.  For the monohull, we strip off the side amas and widen the center hull to maintain ship stability.  But bad news.  A wider hull requires a larger engine, and associated support machinery.  In general, the machinery accounts for approximately 50% of the total build cost.  The structure is only around 25-30% of the build cost. [3]  Adding larger machinery costs twice as much as adding extra structure.

4.0 Applications

You see trimarans most often in high speed vessels and the occasional military vessel.

• Car ferries
• Military ships

One of the first experimental military trimarans was the Triton, a steel vessel with a displacement exceeding 1000 MT. [3]  (Figure 4‑1)  These are not little vessels.

Don’t think of trimarans as an expensive hullform.  The prevalence of trimarans with expensive ships is mostly a coincidence.  Imagine if you wanted a high speed ship.  First step is pick a trimaran hullform.  But for high speed, you also build it out of aluminum and load it with powerful engines.  Those are all high priced decisions that get imposed on the trimaran hullform.  The hull shape does not drive the price tag, and trimarans are not limited to high speed.

Aker Arctic even investigated using trimarans as an icebreaking tug. (Figure 4‑2)  Aker found the trimaran configuration especially useful for cutting wide channels through the ice with less power.  Trimarans are just a hull configuration.  How you use the hull is up to you.

5.0 Conclusion

Don’t let the previous trimarans limit your imagination.  The trimaran hullform bridges the gap between monohulls and catamarans.  It offers some advantages of both deadweight capability and larger deck area.  Primarily, trimarans deliver ship stability in a very power efficient package.  What uses can you imagine with that flexibility?

Catamaran vs Trimaran: Choosing the Perfect Multihull Vessel

26th mar 2023 by toi williams.

The debate over whether catamarans or trimarans are better boats has been going on for a long time without resolution, but the reason is understandable. The truth is that despite their many similarities, catamarans and trimarans have distinct characteristics that set them apart from each other, so each type of vessel offers a distinct boating experience. The catamaran vs. trimaran debate largely boils down to personal preference and how you intend to use the boat. Here are some of the things you need to consider when choosing between a catamaran and a trimaran. 

What Is a Catamaran?

A catamaran is a multi-hulled boat that has two twin hulls connected by a structure supported by a wide beam. Catamarans come in a wide variety of sizes, ranging from small rowing boats to large boats that are big enough to be used as car ferries. The structure connecting the two hulls can be anything from a simple frame with webbing to a superstructure that includes cabin and/or cargo space. Most of the recreational catamarans for sale are designed to hold two to 20 passengers. 

What Is a Trimaran?

A trimaran is also a multi-hulled boat, but it has three hulls instead of two like the catamaran. The middle (main) hull is larger than the two small outer hulls attached to it. These hulls are connected by a lateral beam, wing, or some other form of superstructure, depending on the model. These types of boats also come in a wide variety of sizes, ranging from recreational yachts to ferries. 

Advantages of Catamaran vs. Trimaran

The advantages of catamarans vs. trimarans are mainly based on comfort. Catamarans are spacious boats, known for their large living quarters with plenty of room on board for hosting gatherings and parties. Their popularity has enticed many boat builders to create increasingly luxurious designs on larger and larger boats. The catamaran also has a more classic style that appeals to those who want a boat with a simple, sleek shape. Catamarans are best suited for boating in calm seas, lagoons, and shallow waters.

Advantages of Trimaran vs. Catamaran

The advantages of trimarans vs. catamarans mainly come down to speed. Trimarans are among the speediest boats available, offering lightning-fast speeds on open waters. Many recent winners of notable boating competitions have been won by boaters piloting trimarans. These boats also perform well when heading upwind and are remarkably stable with their three-hulled design. The anchoring gear is installed on the main hull and is easy to deploy. 

Trimaran vs. Catamaran Speed

In the trimaran vs. catamaran speed debate, the trimaran is the clear winner. For long offshore races, trimarans have become the preferred vessels, and boaters piloting trimarans have won the Jules Verne Trophy in every race held since 2010. This is because of their unique design, which has speed and safety qualities that provide significant benefits for boaters. 

The trimaran's third hull makes the boat considerably faster than any other hull form due to the correlation between the boat’s waterline length and its speed. Having more hull distance in the water lets the boat reach higher speeds. Trimarans can also be pushed harder and are more forgiving than other boat styles in racing environments.

That doesn't mean that catamarans are slow. Some styles of catamarans are capable of breaking world records when the boating conditions are right. On downwind runs, a racing catamaran may be quicker than a trimaran, but for overall speed in various conditions, the trimaran comes out on top. 

Catamaran vs. Trimaran Performance

In the catamaran vs. trimaran performance debate, both sides have their advantages. A catamaran is easier to handle and maneuver with the boater having to handle the lines and halyards less often. However, this ease comes at the expense of speed, with cruising catamarans generally traveling slower than comparable trimarans. 

Trimarans are more versatile in their performance, and they perform better than a catamaran when traveling against the current or the wind. Trimarans can be used in nearly all weather conditions, are less vulnerable to drifting, and have less roll motion than a catamaran. However, handling a trimaran requires more work than handling a catamaran, which can be exhausting over long periods of sailing. 

Trimaran vs. Catamaran Efficiency

When comparing trimaran vs. catamaran efficiency, the differences are minimal. Multi-hulled boats are more fuel-efficient than comparable mono-hulled boats due to their hull forms and their lighter weights. Multi-hulled boats also tend to have smaller displacement and shallower drafts than other boat styles. 

The biggest difference in trimaran vs. catamaran efficiency is that catamarans nearly always have twin engines while trimarans generally run with one engine. A trimaran also has less hydrodynamic resistance than a catamaran because it spreads out the displacement across three hulls instead of two. This allows each hull to be narrower and more streamlined.

Catamaran vs. Trimaran Stability

The stability of multi-hulled boats is one of their biggest advantages over mono-hulled vessels. Multi-hulled boats benefit greatly from their wider stance on the water, and their wide beams and floats offer higher stability than a ballasted keel. Multi-hulled boats are also more buoyant because their floats help prevent immersion. When comparing catamaran vs. trimaran stability, the better boat will depend on the conditions on the water.

A catamaran's geometrically stabilized design reduces both heeling and wave-induced motion, providing a stable platform underway and at anchor. However, the catamaran's design is not as suitable for navigating heavy seas as the trimaran's build. The trimaran's three hulls provide excellent stability even in rough waves, but this can also make a trimaran less comfortable than a catamaran when the water is calm.

Catamaran vs. Trimaran Safety

Both catamarans and trimarans are considered to be safer on the water than mono-hulled boats. A catamaran has superior resilience and roll inertia that makes capsizing extremely unlikely. Its speed, steadiness, and ease of motion due to a lack of ballast also contribute to increased safety.

Trimarans are considered the safest multi-hulled boats because their three-hulled design makes them almost unsinkable. Many also have a core made of high buoyancy foam, helping them stay afloat even in the most brutal storms. Weight centering and a complete anti-drift scheme also make the boat safer for everyone aboard.

Trimaran vs. Catamaran Maintenance

Comparing trimaran vs. catamaran maintenance costs shows that many of the costs will be very similar for both types of boats. These costs include yearly boat service and repairs, annual haul-outs, and insurance coverage but exclude major upgrades. You will also have to budget for dockage, winterization, and storage for each year if you don't intend to use the boat year-round. 

Boaters are advised to budget between 5% and 10% of the boat's value for annual maintenance costs if their boat is less than five years old and a little more if the boat is older than that. Different maintenance jobs can be charged in different ways. Sometimes, the charges are based on the length of the boat while other charges are based on the number of hours worked.

Catamaran vs. Trimaran Cost

If you are looking for an affordable seafaring vessel, catamarans and trimaran are both good choices. There are many reasonably priced catamarans and trimarans suited for families as well as other models that provide more luxury for an additional cost. The materials that the manufacturer used to build the boat and the electronics included will also impact the price of the boat.

With so many different factors impacting the cost of different boats, you should choose the best vessel for you based on the features you want as well as your budget. Doing some research using the information on Rightboat's listings will help you find the right combination of quality and affordability you are looking for. Because we offer both new and used boats, nearly any boater will be able to find a boat in our listings that fits their needs.

Trimaran vs Catamaran: What are the Differences?

The debate between trimarans and catamarans has been raging for years, with no clear victor in sight. Despite their long-standing popularity as cruising vessels, trimarans have seen a resurgence recently – but what sets them apart from catamarans? The subtle differences lie mainly within the hulls; while monohulls are distinguishable several yards away, distilling one multihull from another requires closer examination of characteristics such as living space size accommodations, seaworthiness ratings , speeds achieved on test runs.

With these variables to consider – along with personal preference – deciding which vessel is right may be difficult indeed!

Performance and Stability: two distinct sailing experiences

The stability of a catamaran vs a trimaran.

When sailing on a monohull in strong winds, the boat can potentially capsize due to its single hull and lack of floatation. On the other hand, multihulls such as catamarans are more buoyant because they have two floats that help prevent immersion; however it still may be uncomfortable when navigating heavy seas. For the most optimal sail experience with great stability even through rough waters–pleasure trimarans provide an ideal combination! Three connected hubs act like small wheels over rippling waves while providing excellent comfort aboard no matter what conditions lie ahead!

The wind and its influence on the performance of multihulls

In sailing, trimarans outperform catamarans in a headwind situation. Their unique hull design features both daggerboards and central weight focus which allows them to counteract the thrust of wind better so as to stay on course rather than drifting away like their counterparts do. This subtle difference makes significantly more efficient vessels resulting in overall faster speeds when heading into the wind – making trimiras an ideal choice for less experienced sailors seeking reliable performance!

Looking beyond traditional catamaran styles?

Trimarans such as DragonFly boast amazing features thanks to its “Swing Wing” system while Rapido Trimaran offers “an experience like nothing else”—thanks in part due to Morrelli & Melvin architect firm constructing this Vietnam built masterpiece!

For those seeking a luxurious floating lifestyle, the trimarans from shipyard NEEL are second to none! These vessels feature ‘Cockloon®’ areas which seamlessly connect saloons and cockpits – providing uninterrupted living spaces with breathtaking panoramic views. Alongside this is an expansive flybridge offering extra room along with comfortable cabins nestled within their own designated floats for ultimate relaxation. You could say that these modern marvels of engineering provide all you need in one single package – now it’s just down to choosing your destination!

Looking for the perfect blend of stability, comfort and interior space? Look no further than the NEEL 65 – a unique trimaran that boasts roomy cabins thanks to its enlarged volume. Not only does it offer more living area compared with typical catamarans – but also features an optimally aligned central hull which provides extra safety at anchor! So if you’ve been in two minds between these nautical vessels; perhaps this could sway your decision once and for all…

Trimaran vs catamaran safety: the width of trimarans makes them safer

The trimaran stands out as the most secure of its multihull contemporaries. Its superior design consisting of three hulls, effective anti-drift strategies and centre-mounted weights combine to provide it with a groundbreaking 27° righting moment – allowing for excellent stability in even gusty weather or choppy waters. In comparison, catamarans offer just 12° degrees protection against capsize – meaning that the trustworthiness offered by a trimaran is hard to match! Further punctuating this remarkable level of security are features such as buoyancy tanks which ensure that if capsizing does occur, sinking will not be an issue: making trimarans perfect vessels for sailing’s safety conscious connoisseurs.

Racing trimarans

In the last decade, trimarans have surged in popularity for racing purposes due to their enhanced speed and safety capabilities. Their stability on rough seas allows them to be pushed further than catamarans can go without sacrificing control of the vessel; this is why most multihull races since 2010 have been captured by a trimaran! The Jules Verne Trophy has not seen any different – all winners since its start in 2010 are proud owners of these three-hulled vessels.

How to make the right choice between a monohull, a catamaran, and a trimaran?

No matter what sailing adventure you have in mind and the destination, it is essential to select a vessel that will fulfill your dreams while meeting all of your demands. Make sure to pick wisely!

Choose a monohull sailboat if you like sailing!

Nothing quite compares to the feel and freedom of a sailing adventure aboard your own monohull sailboat. With its large, retractable keel, you can explore shallow waters where other boats may not venture while taking in stunning vistas from beyond the coastline. Enjoy an unforgettable experience with every rustle of wind across your sails!

Pick a catamaran if you like volume and calm seas

TThe catamaran is perfect for adventurers seeking the tranquility of sailing with family and friends. With a spacious interior, multiple cabins equipped with bathrooms, and an enviable amount of storage capacity above 12m in length – it’s easy to see why these boats have become so popular! However when navigating more turbulent seas keep in mind that their windward grip may make maneuvering tricky; but Catana’s boat selection has you covered thanks to its range featuring daggerboards allowing captains ultimate control over any situation.

Pick a trimaran for a good combination of volume and performances

For those looking for a sailing experience like no other, trimarans are the perfect answer. They offer lightning-fast speeds and truly exhilarating performances on open waters – all while providing plenty of roomy living space comparable to catamarans of similar size! Whether you’re attempting an adventurous transatlantic crossing or simply want to enjoy some pleasant cruising around the world, selecting a recreational trimaran could be your best bet.

Enjoy cruising on the NEEL 51 , a unique charter yacht that offers plenty of space without sacrificing performance. This trimaran-inspired vessel is perfect for travelers who want to explore new destinations quickly and safely — with speeds twice as high as other options!

After looking into the differences between catamarans and trimarans, we can conclude that they each offer distinct sailing experiences. Catamaran sails offer a sense of comfort and stability for extended cruising trips and luxurious living spaces, while trimarans are better on performance, safety – due to the increased width of their hulls – and speed when racing. Ultimately though, it all comes down to personal preference when it comes to choosing between a monohull, a catamaran or a trimaran. If you want to gain speed and enjoy the thrill of racing, then a trimaran may be your best option; however if you prefer comfort and more space while cruising, then a catamaran may be more suited for your needs. Whichever you ultimately decide to purchase, just make sure that it fits your specific circumstances and requirements.

Whether you’re a fan of stability or speed, there’s one boat that can give you both – the trimaran vs catamaran. Catamarans provide plenty of living space and comfort in calm waters but struggle with choppy seas, while modern trimarans deliver excellent performance even on rough days yet still offer good room to relax onboard. But if vintage sailing is more your style opt for an older-style tri since it won’t be equipped with as much creature comforts!

Catamarans and trimarans are two types of watercraft that rapidly cut through the waves, but when it comes to speed one stands out above the rest. Trimarans have gained a reputation for being fast enough to take on any other vessel in a race – making them an excellent choice for anyone looking to shave precious seconds off their time!

When it comes to safety on the sea, two of the most popular vessels are Trimarans and Catamarans. Thanks to their side hulls, trimarans offer a much greater heeling angle compared with catamarans – meaning they’re less likely to capsize or sink in rough waters. However don’t let that put you off taking out a catamaran – while not as secure as its three-hulled cousin – these craft still provide plenty of stability for your seafaring adventure!

If you’re looking for an affordable seafaring vessel, the choice between a catamaran or trimaran can be daunting. With numerous factors that impact cost – from age and length to comfort levels and desirability – it’s often hard to tell which of these two sailing vessels will fit your budget best. But with some research, you’ll find just the right combination of affordability and quality suited perfectly to your needs!

Monohull or multihull: which is best for blue water?

• Chris Beeson
• March 29, 2016

As former editor of Yachting World, David Glenn has plenty of experience of both monohull and multihull cruising. Here he weighs up the pros and cons

One hull, or two? Your choice will define your life afloat Credit: David Glenn

Through the binoculars I could see masts off Basil’s Bar on Mustique. Their lack of movement suggested a fine anchorage, sheltered from the tradewind-driven swell that builds up in the channel between Mustique and Bequia. It soon became apparent that most belonged to cats, immune from the rolling monohulls like ours would endure if we were to stop in this otherwise enticing bay.

More anchorages in a multi

Cats galore off the Soggy Dollar Bar, Jost van Dyke: too shallow for a fixed keel monohull of similar size

Stability is one of the truly great advantages of a cruising multihull. Not just at sea where the tiresome business of heeling is something that simply doesn’t – or shouldn’t – happen to any great extent, but at anchor too. It dramatically widens one’s choice of anchorages to include those affected by swell – not uncommon in the Caribbean, for instance, where a subtle change in wind direction can make a previously flat calm anchorage unbearable in a monohull. Its comparatively shoal draught widens the choice still further.

I grew up with monohulls, own one, and frankly wouldn’t consider a multihull for the sort of sailing I do. In northern European waters, marina berthing is a regular necessity and completely safe open anchorages are few and far between.

No rolling or heeling, 360° views and one-level living, as here on a Lagoon 52, appeal to many

But if I were to undertake some serious blue water cruising and I wanted family and friends genuinely to enjoy being afloat, particularly those less experienced, a multihull would have to be a consideration. I would have to put aside the question of aesthetics – let’s face it, they’re ugly beasts – and forego that unique and satisfying sensation of a yacht sailing well, because to date I have not experienced it in a cruising multihull. And that’s quite a sacrifice.

More space in a multi

My attitude changed after chartering catamarans in the Caribbean and Mediterranean. The need to accommodate two families comprising largely of teenage children made the choice of a multihull a no-brainer. In a 46-footer we could accommodate a party of 10 in comfort and the paraphernalia demanded by youth, like surfboards, windsurfers, kites and snorkelling kit, without feeling jammed in.

One-level living makes a big difference when sailing as a famly

The cavernous berths in the ends of the hulls, the wide saloon-cum-galley with its panoramic view and the inside/outside lifestyle made possible by the juxtaposition of the big aft deck and the same level saloon, got the entire crew onside instantly.

As an outside living space, with a trampoline at one end and a massive aft deck at the other, there is simply no comparison with a monohull of the same length. So space, linked to stability, makes for an experience that everyone, even the timid and novices, will find hard not to enjoy.

No speed difference

A multihull, like this Moorings 46, has abundant stowage on deck and below, but filling it all will slow her down

Load-carrying ability is a double-edged sword. On the up side there is room for a big crew and its kit, much more fresh water tankage than a monohull, eliminating the need for an expensive, temperamental watermaker, and finding space for a generator should be easy.

On the down side the temptation to overload will probably cancel out any perceived performance advantage. Multihulls can be relatively quick in the right offwind conditions, but if they are heavily laden – as they will be for blue water cruising – there really is no significant speed advantage.

The Gunboat 66 Phaedo 1 piles on the speed, but for blue water cruisers, comfort and stowage is more important than pace

Some new designs such as Gunboat and Outremer have concentrated on performance, but most clients aren’t overly concerned about outright speed and are happy to trade performance for the considerable comfort offered by brands like Lagoon, Broadblue, the Fontaine Pajot stable, Leopard, Catana, Privilege and others.

Mono sails better

Monohulls, like this Amel 55, sail better upwind, and her ballast keel adds displacement, which means comfort when it’s rough. Multihulls can develop an unpleasant motion in a big sea

Upwind, most cruising multihulls won’t point like a monohull with a deeper keel, and when it gets lumpy and fresh, the motion can become distinctly unpleasant. You have to keep a particularly careful eye on sail area too, but more of that in a moment.

In 2011 I was involved in a test of three cruising catamarans and among my fellow judges was multihull design legend Nigel Irens. He pointed out that catamaran buyers have voted for accommodation (which means weight) over performance, so the dilemma of mixing the two has largely disappeared. With it went the spectre of capsize because, relative to their displacement and beam, the modern cruising catamaran is under-canvassed. But that doesn’t mean that sailors can simply set sail and go in any weather.

‘Speed limits’ on a multi

On a multihull, it’s more important to know when to reef. Set speed limits and stick to them

Also on the panel was Brian Thompson, the lone Brit on board the 130ft French trimaran Banque Populaire V that sailed around the world in under 46 days. He told me that the tell-tale signs for knowing when to reef are far more subtle on a multihull. Apart from instinct, Brian suggested monitoring boat speed closely and having a speed limit to trigger reefing. It is easy to overlook a building breeze when bowling along downwind in a multihull, which is going faster and faster. ‘Keep your boat speed within safe limits you should not get into too much trouble,’ he said.

People often ask about anchoring a multihull, which is important as a multihull will spend a lot of time at anchor. Squeezing into a marina can be nigh on impossible, and expensive if you can get in. An essential piece of kit, which should be standard with a new boat, is a bridle that runs from either hull and keeps the anchor cable on the centreline. In many ways this is easier than anchoring a monohull as it prevents the ground tackle from fouling the hulls.

If you do get alongside a marina pontoon you will soon discover another modern cruising multihull issue: excessive freeboard. It’s worth investing in a portable ladder for those marina moments. Of more concern is MOB recovery. There are bathing platforms on both hulls of most new boats, but it’s not the place to be if a yacht is pitching in a heavy sea. So considerable thought needs to be applied to retrieving an MOB if the worst happens.

The recent and dramatic increase in numbers of multihulls going blue water cruising is certainly testament to their appealing ‘lifestyle’ attributes, but one must bear in mind that they are not a fix for all liveaboard cruising challenges. It’s just a different way of doing things. The elements remain the same and can inflict just as much punishment for the unwary on a multihull as they can on a monohull.

What is a Catamaran? Catamaran Boats Vs Monohull Vs Trimaran

Olivia benjamin.

• July 2, 2023

Diving into the world of catamarans, those magnificent vessels revolutionized the boating industry with their stability, speed, and remarkable spaciousness. The secret to their superiority? It’s all in the design, with two sleek hulls, side by side, linked by a bridge deck. That’s the design secret that set them apart from traditional single-hulled vessels.

Catamarans have become the first-choice vessel for sailors, cruising fans, and yacht chartering enthusiasts with their exceptional stability, unparalleled comfort, and outstanding performance, even under challenging weather conditions.

So, get ready to reveal the charm and brilliance of these awesome watercraft.

What is a Catamaran?

A catamaran is a type of yacht or boat characterized by its unique design featuring two parallel hulls connected by a bridge deck. This twin-hulled structure sets catamarans apart from traditional monohull boats and offers a range of advantages that have made them increasingly popular in the boating world.

Stability sits at the top of a catamaran’s list of advantages. The two hulls offer a broad base, significantly enhancing stability even in rough waters.

In addition to stability, catamarans hold a reputation for their spaciousness; a feature monohull boats find hard to match. A catamaran offers an inviting living space above and below the deck thanks to the wide spacing between the dual-hull structure.

Catamarans come in various sizes, from compact versions perfect for a day’s sail to larger variants designed for extended cruising or fishing. This versatility enables each boater to find a catamaran that fits their specific needs and desires.

Catamaran vs. Monohull

In the world of boats, the choice between a catamaran and a monohull is pivotal. Both boats offer unique advantages and face their challenges. Being aware of these differences can guide you in making a well-informed decision. Let’s explore some of these differences:

Sailing Performance

Thanks to their dual-hulled design, catamarans are known for their speed and stability. This configuration enables them to move through the water with minimal resistance, resulting in higher average speeds.

Conversely, Monohulls have one hull to navigate through the water, which may result in a marginally slower sailing experience.

Maneuverability

Catamarans gain the upper hand in shallow waters with their twin hulls. The twin hulls allow it to have a shallower draft, meaning that it can sail in waters that are too shallow for monohulls.

This grants catamaran owners access to exploring remote coves and anchoring in secluded bays, mostly inaccessible to monohulls.

Catamarans are appreciated for their tight turning circles and easing handling in marinas and tight spaces. However, monohulls boast superior maneuverability under sail due to their single-keel design.

Catamarans offer ample space due to their wide beam. The dual hulls facilitate generous living space on the deck and below, providing room for multiple cabins, saloons, and well-equipped kitchens.

In contrast, monohulls offer a traditional sailing experience with their characteristic lean and heel, which some sailing purists prefer.

Catamarans, especially larger ones, are often costlier than monohulls. This is due to the increased materials and labor required to build a catamaran’s twin hulls. Furthermore, the larger sail area and rigging of catamarans can lead to increased maintenance costs.

However, catamarans typically have higher resale values due to their popularity and demand in the market.

Catamaran Vs Trimaran

For sailing enthusiasts ready to explore the open waters, multiple choices for the type of boat with varied options. Among these, catamarans and trimarans are two popular choices that offer distinct features and benefits.

Both catamarans and trimarans are designed with multiple hulls. These boats have unique features catering to different sailing preferences and conditions.

Let’s explore some of differentiating factors between these two unique vessels:

Number of Hulls, Performance & Stability

As its name implies, a catamaran features two parallel hulls, while a trimaran three hulls. The hull count influences the boat’s stability, maneuverability, and overall performance on the water.

Catamarans are widely recognized for their exceptional stability and sailing performance. The twin-hulled design provides a large and stable platform on the water. With a wide beam and low center of gravity of a catamaran make it less likely to tip or heel dramatically during sailing, contributing to an overall sense of safety and stability onboard.

In contrast, trimarans, with their three hulls, offer a unique combination of stability and speed. The central hull, or the “ ama ,” is typically larger, offering buoyancy and stability. Two smaller hulls, known as the outriggers or “ amas ,” further contribute to stability and help counterbalance the forces acting on the boat. This tri-hulled design allows trimarans to sail at high speeds while maintaining stability.

While both catamarans and trimarans offer exceptional stability, catamarans generally have a wider beam. The twin-hulled catamaran design provides ample living space above and below the deck. Nonetheless, the narrower beam of trimarans may restrict the space available for living and other features. However, trimarans are still ideal for those prioritizing performance and exhilaration on the water.

With their dual hulls, catamarans have a distinct edge in shallow waters and constrained spaces. Their design provides a shallower draft, opening up exploration opportunities in shallow anchorages and exploring areas inaccessible to monohulls or even trimarans.

The twin-hulled design enables catamarans to efficiently deliver tight turning circles, making them highly maneuverable in marinas and crowded harbors.

Despite showcasing excellent maneuverability, Trimarans may experience comparatively deeper drafts due to the additional hull, potentially restricting their access to certain shallower areas.

Sailing Experience

Due to their wide beam and sturdy build, catamarans generally experience minimal heeling or leaning while sailing.

In contrast, trimarans might experience slight leaning during sailing, giving sailors a more traditional sailing experience that may be attractive to some sailors.

Assessing the cost between catamarans and trimarans can be complex. The final price tag usually depends on factors such as design intricacies, construction complexity, and the equipped amenities on the boat.

With their multi-hulled design, both catamaran and trimaran often demand more materials and craftsmanship, which can escalate the total cost. These boats typically have larger sails and rigging, increasing maintenance expenses.

Nonetheless, the cost will hinge significantly on the quality and sophistication of the design and equipment involved; hence, categorically declaring a cheaper option may be challenging.

Types of Catamarans (Sailing Catamarans Vs. Power Catamarans)

Catamarans are available in various shapes and sizes, catering to boating requirements and preferences. Sailing and power catamarans are the main types, each having distinct features and advantages.

Sailing Catamarans

Sailing Catamarans are designed with the thrill of cruising the sea under wind power. They offer excellent stability, a desirable trait for those seeking a smooth experience even in rough waters. The wide beam minimizes seasickness risks and lends itself well to overnight cruises.

Regarding propulsion systems, Sailing Catamarans use wind force captured by sails for movement. This natural, renewable energy source offers an eco-friendly and tranquil boating experience.

However, modern sailing catamarans also have auxiliary engines that assist during calm winds or intricate maneuvering in harbors.

Power Catamarans

Power catamarans are designed for those who prioritize speed and efficiency. These particular catamarans are equipped with powerful engines that facilitate them to reach high speeds effortlessly.

While the fundamental design of Power Catamarans mirrors that of Sailing Catamarans – the wide beam with dual hulls – the power source differs dramatically. The twin-engine setup (one per hull) allows for higher cruising speeds and improved maneuverability.

Power catamarans are known for their superior fuel efficiency, an essential consideration for day-long expeditions. Despite prioritizing speed, they don’t sacrifice comfort; the power catamaran’s design boasts spacious interiors similar to Sailing Catamarans.

Advantages of Catamaran Boats

Catamaran boats offer numerous benefits, making them an attractive option for experienced sailors and those new to boating.

1. Stability : Catamarans offer increased stability over monohull boats due to their wider base and even weight distribution. This stability is noticeable during sailing, anchoring, and even when exploring shallow waters, providing a more comfortable experience for passengers.

2. Shallow Draft : Catamarans can easily navigate in shallow waters due to their low draft. This feature allows for exploring narrow coastal areas, coves, and bays that may be inaccessible to larger monohull boats.

3. Comfort and Space : The parallel hulls of a catamaran create more living space. This includes a spacious kitchen or galley, comfortable sleeping quarters, generous storage space, and a large multipurpose deck area.

4. Power and Speed : Catamarans are known for their speed and performance. Their twin-hull design reduces wind and water resistance, allowing for increased speed. Their shallow draft also allows faster navigation in shallow waters or narrow paths.

5. Fuel Efficiency : Catamaran’s design contributes to their fuel efficiency. The wider base reduces drag, while its stability allows for constant sailing without extensive adjustments, leading to less fuel consumption.

6. Redundant Equipment: With duplicate systems and backup options for essential systems such as engines, steering, and electrical systems, ensuring uninterrupted functionality and safety even in the event of a failure or mechanical issue.

Drawbacks of Catamarans

While catamarans have unique design advantages making them popular, they also present certain limitations.

1. Responsiveness : Catamarans have less responsiveness due to their wider beam and twin hulls. This means they require more effort and time to turn, particularly in tight spaces or crowded marinas.

2. Pounding in rough seas : Catamarans may experience a pounding sensation when encountering large waves, causing discomfort and potentially increasing damage risk.

3. Wider beam challenges : The wider beam of catamarans can make finding suitable docking spaces difficult in crowded marinas or tight anchorages. Navigating through narrow channels or under bridges can also prove challenging.

4. Fuel efficiency at high speed : In strong headwinds or rough seas, the reduced drag of a catamaran increases speed but requires more fuel to maintain the higher speed.

5. Higher purchase and maintenance price : Catamarans often have higher purchase prices. The double hulls and equipment lead to increased maintenance costs and potential failures. Also, catamarans often require wider slips or specific berthing arrangements, resulting in potentially higher costs.

6. Sailing Performance : Due to their wider beam, Catamarans struggle to sail close to the wind. Their larger wetted surface area can create more drag when sailing upwind, impacting their performance in stronger wind conditions.

It is important for potential catamaran owners and operators to carefully consider these factors and choose a vessel that aligns with their specific needs and intended usage.

Tips for Sailing a Catamaran

Sailing a catamaran is an exciting experience but demands unique handling skills & knowledge. For a smooth sailing adventure with a catamaran, keep in mind the following tips:

1. Know Your Catamaran’s Design : Familiarize yourself with the boat’s layout, controls, sails adjustment, handling the rigging, and engine operation before setting sail. If necessary, understand how to operate the engines to ensure a safe journey.

2. Monitor Weather Conditions : Always check the weather forecast before departure. Remember, a catamaran’s wide beam makes it susceptible to strong wind gusts, so adjust your sails and course accordingly to maintain control.

3. Practice Maneuvering : Operating a catamaran requires skill and caution, particularly in tight spaces like marinas or crowded harbors. Practice maneuvering skills in open waters before docking or anchoring in challenging areas. Know how to use the engines efficiently for forward, backward, and sideways movements, keeping the boat’s draft in mind to avoid grounding or hitting reefs that could harm the hulls.

4. Know Your Depths : One of the major considerations when sailing catamarans is their draft – the minimum depth of water a boat sinks to when loaded. Being aware of the draft of your catamaran prevents you from running aground or damaging the hulls on underwater obstacles or shallow areas. Regularly use your depth finder, follow up-to-date nautical charts, and remember that conditions can change rapidly.

5. Harness the Wind : To maximize your sailing efficiency, understand and use the best sailing angles for your catamaran since this varies among different catamaran models. Learn how to trim your sails properly to harness wind power effectively and constantly watch for wind direction and speed changes to adjust accordingly.

6. Maintain Your Catamaran : Regular maintenance of your catamaran is crucial to ensure its optimal performance and longevity. Establish a routine check for potential issues, including regular hull inspections, rigging wear and tear, and engine checks if applicable. Cleaning the vessel regularly prevents algae build-up and exposes hidden potential issues that might otherwise be overlooked.

7. Plan Your Berthing: The increased beam size of a catamaran compared to monohull sailing yachts means you’ll need a wider space for berthing. Pre-planning your berthing locations can save you from avoidable berthing complications. Always approach the berth safely and slowly, and be mindful of surrounding boats and hazards.

8. Prioritize Safety : While the stability of catamarans can make them feel exceptionally safe, it’s important never to compromise on safety standards. Ensure everyone on board is familiar with basic safety protocols, knows how to use lifesaving equipment, and knows where it’s stored. Regular checks and upkeep of safety gear, including lifejackets, fire extinguishers, and flare kits, are essential.

Remember, these starting tips merely scratch the surface regarding sailing catamarans. Continuous learning and accruing experience on the water are crucial to becoming a skilled catamaran sailor.

Catamaran Boats FAQs

When it comes to catamarans, several questions are often circulating in the minds of novice and seasoned sailors. Let’s address some of these commonly asked questions:

What is the difference between a catamaran and a monohull boat?

The most significant differences between a catamaran and a monohull boat are their hull design. Catamarans feature two hulls connected by a bridge deck, while monohulls have a single hull.

Key advantages of catamarans include greater stability, spacious living areas, and a shallower draft. Conversely, monohulls are typically known for their traditional sailing experience and ability to slice through waves.

How does the cost of a catamaran compare to a monohull?

Catamarans are generally more expensive than monohull boats of similar size and features due to the increased materials, labor, and engineering necessary to build them.

Furthermore, catamarans might have higher maintenance and operating expenses due to their dual hulls and larger living spaces. However, it’s important to remember that catamarans provide more living space and stability for those who value comfort and spaciousness.

What is the typical draft of a catamaran?

A catamaran’s draft refers to the hull’s depth below the waterline. Catamarans are known for their shallow draft, which allows them to navigate in shallower waters compared to monohull boats.

The specific draft varies depending on a catamaran’s size and design but typically ranges from 2 to 5 feet. This shallow draft is advantageous in coastal areas, island hopping, or exploring shallow-water destinations.

Can catamarans be used for racing?

Yes, catamarans have become increasingly popular in the realm of sailing races. Racing catamarans are designed with lightweight materials and streamlined hulls that enable them to reach remarkable speeds.

They also feature advanced sail systems that boost performance, such as rotating masts and asymmetrical spinnakers. Catamaran racing is both exhilarating for participants and a fascinating spectacle for spectators.

Are catamarans suitable for long-distance cruising?

Catamarans are well-suited for long-distance cruising due to their stability, spacious living areas, and efficient sailing capabilities. With their wider beam and dual hulls, catamarans offer abundant living space above and below the deck.

This makes them comfortable for extended periods on the water, providing ample room for supplies, equipment, and socializing. Furthermore, the impressive stability of catamarans allows for a smoother ride, even in rough seas.

Monohull Vs Multihull

There has been a debate in the world of sailing foe some year over monohull vs multihull. Is one superior? What are the benefits and drawbacks of each? It’s a layered question and both have some great upsides and a few downsides. Is one better? That’s likely up to the individual sailor. But we can help you make that decision by breaking down each one.

What are Monohull Sailboats?

A monohull vessel is a boat with one single hull. This is your traditional sailboat , fishing boat, yacht, whatever you please. As long as you only see one hull in the water, it’s a monohull.

What are Cruising Catamarans?

Multihull boats are often called catamarans or cruising catamarans. That’s how you describe a boat with two hulls side by side. If you have three hulls it’s still a multihull but you might call it a trimaran. The word “catamaran” is from the Tamil language. It means “logs bound together.” Ironically, these older catamarans which gave us the modern word were not multihulled boats at all, but monohulled rafts. Go figure.

Are Cruising Cats Better than a Monohull Sailboat?

Here’s the question every new sailor wants to know. Which boat is best? It’s not as easy as all of that, though. Let’s break down some of the differences.

Monohull Design: These boats have a keel under the hull to aid in balance and stability. If a monohull sailboat were to be pushed over, gravity would help that heavy keel right it again assuming it wasn’t capsized and taking on water. That said, a monohull may heel as much as 20 degrees at speed. The interesting thing about this is that it’s either a benefit or a drawback depending on how you like to sail. For some sailors, this heeling is part of the adventure of being at sea. For others it’s a nuisance that spills drinks.

Monohulls are traditional boats and the oldest sailing vessels. They are well balanced and sleek. For a lot of sailors, a monohull is ideal because there seems to be less boat to worry about. A lot of sailing is based on the idea that you’re in a monohull vessel. You might consider this classic sailing.

Multihull Design: Because the boat is balanced on multiple hulls, they do not displace as much water as a monohull. The weight of the boat covers a much larger area. Living quarters on a catamaran can be above deck and below.

The stability of a multihull cat is superior because of this larger area. A monohull can tip with too much sail where most cruising cats will not. Multihull boats rarely heel more than 5 degrees up to 10 degrees or so at speed. As such, sailing in a multihull is often considered more relaxing, if that’s what you’re looking for.

One thing to be aware of is that, with little heeling, you may be slow to notice bad weather. A harsh wind will push a monohull around a lot more than a multihull. Since the heeling is so slight in a multihull, the wind can really pick up before you start to notice you may be heading into dangerous weather.

Monohull Space: The living space in a monohull is typically secluded below deck. This is a limitation of the design because where else would you put any living quarters?

Multihull Space: Many sailors looking for creature comforts at sea prefer multihull sailboats because of the extra space. A multihull vessel will offer as much as 50% more space than a similarly sized monohull. Remember, you have two decks here and maybe a flybridge. This means more storage space as well. But, as we will see when we cover boat speed, this does come at a cost.

Monohull Comfort: A monohull boat will have some sway and that can lead to seasickness for some people. You get some roll and pitch that can’t be avoided. That said, for those who are used to it, it’s a very smooth motion.

Multihull Comfort: Seasickness is much less of an issue on a catamaran. The ride is stable and it means sleeping and cooking are relatively safe and comfortable as well. The big downside for comfort with a multihull is the slapping. It takes a while to get used to the water slapping against the hull in a catamaran. This is something you don’t experience in a monohull.

Monohull Appearance: This is a tough one to judge. After all, beauty is in the eye of the beholder, right? But many people do consider monohull boats to be sleeker and more visually appealing. Does that mean much on the open water? Maybe not. But think of it like a sports car. No one “needs” a Ferrari when a Volvo will get you there, too, but they certainly look cool.

Multihull Appearance: Because of the wide construction, catamarans are somewhat clunkier in appearance than a monohull boat. Not everyone feels this way but some people do consider multihulls uglier overall. This won’t affect performance in any way, of course.

Monohull Speed: The speed of a monohull boat is consistent and reliable but it’s generally slower than what you’d experience in a multihull. In fact, most cruising multihulls can get close to 25% more speed than a monohull sailboat. If you bump up to a trimaran they even sail faster. But that does come at a cost.

Multihull Speed: Even though a cruising cat can be faster, it won’t always be faster. A monohull sailboat is very consistent when it comes to speed. A catamaran is not. If you have a multihull boat that’s loaded with gear, it’s going to slow down noticeably. They have to stay light if you want to experience that speed. This is something most people do not consider, that the potential speed advantages will almost certainly be wiped out for any kind of serious blue water cruising.

So on a day trip for fun, you might choose a catamaran for the wind in your hair. But if you wanted to go on an extended voyage and still make good speed, a monohull could prove superior or at the very least equal. In practical terms, we don’t think there’s really much of a difference overall.

Monohull Sailing: When you’re pointed upwind, a monohull sailboat really shines. While a multihull is more stable much of the time, on rougher seas a monohull’s keel gives good balance and displacement. That makes for a better experience overall.

Multihull Sailing: Multihulls don’t point the same upwind as a monohull. As the waves pick up and the water gets rough, the feeling on a multihull goes from being stable and steady to decidedly unpleasant.

Monohull Anchoring: You do have to deal with limited anchorage when you’re in a monohull. A little bit of swell or shifting wind can make anchorage in a monohull a real problem. When you pull into a slip, docking and slipping fees will be much less in a monohull thanks to the limited space you’re taking up.

Multihull Anchoring: It’s typically much easier to manage this in a multihull. Changes in wind and swell have little effect on a multihull. You can also make use of many more locations not accessible to a monohull boat. The downside to this is trying to find space at a slip. Many slips won’t have room for a larger catamaran which is why you’re so likely to see them all anchored in a little bay or cove.

Monohull Maneuverability: Maneuvering a boat with a single engine or sails can take some practice and effort. This again is one of those things that some think is a drawback but others enjoy. There’s also the possibility that you’ll have better luck maneuvering a monohull in tighter spaces. If draft is not a concern, a monohull handles narrow rivers and channels better.

Multihull Maneuverability: The maneuvering of a multihull vessel can be a lot tighter and easier than a monohull. If you have two engines on a catamaran you can pull off a very tight 180 turn in a pinch, at least compared to a monohull. This makes navigating some marinas a lot easier.

Monohull Reliability: There is nothing inherently unreliable about the design of a monohull boat. These are, afterall, the old standby. But as we’ve seen there are some aspects that can be considered drawbacks. But a well made monohull boat should be reliable for many years.

Multihull Reliability: Like a monohull, there’s nothing that would make a multihull inherently unreliable. But it’s worth noting that if you have a catamaran with two engines, you have added reliability. If the engine on a monohull fails, you may end up stranded. If a multihull engine fails, you may still have a second to get you home.

Multihull Safety : Generally speak, a multihull boat is safer. Less heel means they are less likely to flip or capsize. And, if they do, multihull boats are far less likely to sink. The speed of a multihull can be considered a benefit as it can give you an edge both in outrunning poor weather or getting to help in an emergency. Enhanced maneuverability can help avoid danger. Finally, the potential for an extra engine can also get you out of trouble as well.

It is possible to flip a multihull boat, but not easy. You’d likely need to be experiencing very high winds and waves to do this.

Monohull Draft : Your monohull boat will have a sizable keel under the water. For that reason, you’re going to need to avoid shallow waters. This can be a drawback for navigating some rivers and inlets, as well as getting closer to shore.

Multihull Draft : The shallow draft on a multihull means it’s easier to get a catamaran closer to shore. You can also make your way down some rivers more easily as a result. It’s entirely possible to take a catamaran right up onto some beaches. This is an absolute impossibility for monohull boats.

Monohull Costs : A monohull will almost certainly cost less to buy than cruising multihulls. Maintenance and upkeep costs are usually lower as well. If you’re on a tighter budget, a monohull is typically a better choice.

Multihull Costs: Aside from initial costs, catamarans often have higher associated costs. You’ll need double dock space and that means double dock fees. Also, because you have two of everything, you need to essentially do double maintenance. The major cost benefit for a cruising multihull is that you can expect it to have a higher resale value one day as well.

Fuel efficiency is a point in favor of the cruising catamaran. Less drag means it uses fuel more efficiently so you spend less to go further.

The Bottom Line

There are a lot of advantages to sailing with a multihull vessel these days. In fact, sailing catamarans really outshine monohull boats in nearly every regard that we have listed. But does that make them better? Honestly, it’s not a fair question. They’re two different things. They have advantages and they may be better for you and how you want to sail. But you may also really prefer sailing a monohull. You may like the look and the challenge and the feel of the boat better. Any sailor who has tried both knows there really is a totally different feel to taking on the sea in a monohull versus a multihull.

We recommend trying both if you get a chance. You may agree that a multihull has many more benefits for you and your family. But maybe a monohull is still the best choice

Neel 43 on test: Is three the magic number?

• September 17, 2021

Can’t decide between a monohull and a catamaran? The surprising truth is that a fast cruising trimaran, like the Neel 43 could be the ideal solution. Rupert Holmes reports.

Product Overview

Manufacturer:, price as reviewed:.

Until recently it would have been easy to assume the pioneering cruising trimarans of the 1960s and 1970s showed that cruising on three hulls has too many drawbacks to be viable for most, despite the extra space and speed they offered. However, the past decade has seen a resurgence of lightweight fast cruising designs, with spacious accommodation, led by La Rochelle-based yard Neel who recently launched their Neel 43 trimaran.

This latest model, a Marc Lombard-designed 43, is one of those rare boats that defies both expectation and easy classification.

The Neel 43 has the deck space and massive coachroof of the most spacious of cruising catamarans, yet is at least three tonnes lighter than most 42ft cats.

We we tested the Neel 43 in La Rochelle, France with an onshore, 12-16 knot wind with a slight to moderate sea. Photo: by Olivier Blanchet

Another surprise is the low wetted surface area once the windward ama lifts out of the water. Each hull has a narrow waterline beam, so wetted surface area is a fraction of that of a catamaran of similar size. Combined with the light displacement this translates into a boat that’s surprisingly quick.

Neel 43 under sail

After hoisting the mainsail we cut the engine and bore away, unfurling the headsail with the wind on the beam. In only 14 knots of true wind we quickly accelerated to a consistent 10 knots of boat speed.

Sheeting in and squeezing up to a true wind angle of 65° – and 40° apparent wind angle – only saw speed drop by one knot.

Direct Dyneema cables, passing through a minimum of turns, connect the wheel to the single rudder. The helm felt beautifully responsive throughout the test, with a much more direct feel than is generally found on multihulls.

The windward ama lifts easily just out of the water, reducing wetted surface. Stability builds quickly. Photo: by Olivier Blanchet

Tacking proved to be as easy as with a monohull – the boat reliably turned smartly through the wind, with speed rarely dropping much below five knots.

However, visibility from the single raised helm is restricted by the headsail when on starboard tack and by the asymmetric on both tacks.

That there’s a single shallow keel below the centre hull, instead of the two low-profile keels of most catamarans is an important factor in the boat’s handling. It undoubtedly also helps that all the heavy items in the boat, including engine, tankage and batteries, are concentrated low down in the middle of the central hull.

The result is a very comfortable, soft motion that’s easier than that of a typical catamaran, but without the heel of a monohull. In some ways it’s also reminiscent of the easy gait of a heavy displacement long keeler.

The helm felt responsive, with an easy motion. Photo: by Olivier Blanchet

Yet, unlike monohulls, there’s no chance of a broach. Stability builds very quickly after 12-14° of heel is reached, so it takes an enormous force to heel the boat to significantly greater angles. This arguably gives more warning of being overpowered than catamarans, which may generate maximum stability at only 12° of heel.

In addition, the high freeboard means there’s a reassuring amount of reserve buoyancy in the amas, even if the boat is pressed hard in a gust or squall.

On the other hand, a downside of the Neel 43 effectively having a single fin keel is that, unlike most cruising catamarans, it can’t be beached.

Our test boat had standard Dacron sails, so a reasonable set of high-tech sails would undoubtedly see the boat able to squeeze a useful few degrees closer to the breeze without losing too much speed.

Easy motion

However, the reality is that the engine will be used in combination with the mainsail if schedules make a passage to windward essential. Motoring out of the La Rochelle entrance channel head to wind and sea gave a feel for how the easily driven underwater sections behave when motor sailing.

With the single 50hp engine at a comfortable 2,400rpm we made 8 knots, with a gentle motion that didn’t slow the boat.

On turning downwind our speed initially dropped to 6-7 knots at a true wind angle of 150°, until we hoisted the general purpose asymmetric kite. Although it’s not a particularly large sail, this brought the speed back up to 8.5-9 knots, producing our best downwind VMG of 7 knots.

In some ways The Neel 43 sails in a way that is reminiscent of the easy gait of a heavy displacement long keeler. Photo: by Olivier Blanchet

When the breeze picked up a little to 15-16 knots true we sheeted in and luffed up to 115° off the true wind, accelerating to an easy 10.5-11 knots of boat speed. The Neel has so much stability that, even though the sailplan was now generating far more power, there was no perceptible change in heel.

All lines, other than spinnaker sheets, are led to the raised helm station at the front of the starboard side of the cockpit.

Despite its intrinsic speed potential, this is not a boat that’s set up to be constantly tweaked. The deck layout is therefore simple, but efficient. It’s also obviously a cost-effective arrangement, but doesn’t skimp through fitting under-sized winches and other equipment. A powered winch on our test boat took all the effort out of sail handling.

Port and starboard mainsheets – in appropriate colours – give excellent control of the sail shape, without a costly traveller that might endanger the hands of anyone relaxing at the back of the cockpit. The primary sheet is the one on the windward side, while the leeward one gives excellent control of twist.

All lines other than spinnaker sheets are led to the helm station. Photo: by Olivier Blanchet

Headsail sheets are led through a single fixed fairlead. It’s a simple arrangement that minimises coachroof clutter, though twist will increase, spilling wind out of the top of the sail, when it’s partially furled in stronger winds.

43 of the best bluewater sailboat designs of all time

Which yacht is the best for bluewater boating? This question generates even more debate among sailors than questions about what’s…

The optional free-flying working jib can be hoisted furled, so there’s no inner forestay to get in the way when tacking the genoa when it’s not set up.

If I was specifying the sailplan I’d also opt for a Code 0 for use when reaching with the apparent wind well forward of the beam, plus a large asymmetric shaped for deeper downwind angles than the test boat’s all-purpose sail. This would maximise downwind VMG in light and moderate airs.

Technical heart

An unusual, but appealing, feature of all Neel trimarans is the technical area below the saloon floor in the central hull – on some of the larger models this has an impressive 7ft (2.1m) of headroom, which makes for easy access and fault-finding. However the Neel 43 is smaller, which means this is reduced to generous sitting headroom and floor space is limited.

The central section houses tanks, plumbing and batteries, while the engine and steering gear are further aft. Further forward the space is dominated by a large number of electrical items and connections for solar charge regulators, shorepower battery chargers, inverters and so on.

The saloon opens almost seamlessly onto the cockpit. Photo: by Olivier Blanchet

It’s great that these are easy to access, which also serves as a reminder of the vast number of systems that are often hidden out of sight and distributed around different parts of today’s increasingly complex yachts.

However, there’s a downside that can’t be overlooked. These systems are low down in the boat, close to where any water will collect. Fitting a couple of bilge alarms, and making regular checks when underway by lifting the access hatch in the saloon floor, would therefore be sensible precautions. Despite this drawback it’s still an arrangement that has advantages over many installations.

Loft-style minimalism

What about the interior of the Neel 43? Despite the design’s abilities under sail, in this part of the market it’s the accommodation that sells boats. Yet, once again, this is an aspect that defies comparison with others.

Both transoms have swim platforms. Photo: by Olivier Blanchet

The almost seamless blending of indoor and outdoor areas is appealing, but far from unique among today’s multihull designs.

On the other hand, Neel has gone for the ultimate in a loft-style layout that’s refreshingly different. Masses of windows and large expanses of white fibreglass are balanced by just enough fabric and wood trim to give it some warmth.

Reed-style flooring also adds to a feeling of comfort, in the Neel 43 without increasing weight, and can be taken outside to wash and clean.

There’s excellent near-surround visibility – around 300° – when sitting in the saloon and it’s almost as good when standing.

Forward to port is a watchkeeping station with switch panel, and on our test boat a second MFD, VHF and Fusion audio kit, plus 12V outlets and an analogue steering compass here. However, it stops short of being a full chart table that could also be used as an office, so I’m typing this at the saloon table, which is a great place to work, with brilliant views and lots of natural light.

The saloon and galley area has a very open plan layout. Photo: by Olivier Blanchet

In common with other Neel models, the owner’s cabin is on the same level as the saloon. A downside is therefore a lack of privacy, even with the curtains drawn and door closed. However, it’s a beautifully lit and airy space that would suit those who primarily cruise as a couple.

There’s almost no built-in stowage, although the deep bins in the ama outboard of the bunk will take several large kit bags.

Neat touches for every bunk include a reading lamp with built-in USB port, a folding coat hook for jackets, plus a fabric bulkhead-mounted pouch with space for a phone, tablet, sunglasses, notebook and so on.

These may sound like small points, but it’s surprising how many boats lack provision for these items and they therefore quickly get scattered everywhere.

Natural ventilation is primarily via an opening forward facing window on each side of the coachroof – one for the saloon and one for the owner’s cabin.

A berth is separated by the red curtain. Photo: by Olivier Blanchet

There’s also a small opening hatch in the middle of the coachroof and another for the heads. This is a long, narrow compartment off the starboard side of the saloon.

Overall there’s plenty of space and a shower is included, though it’s not luxurious and there’s no option for a second toilet and shower compartment.

The second cabin is right forward in the central hull, accessed by steps just ahead of the galley. This is a pleasant space with more privacy than the owner’s cabin, though the berth is only 77cm wide at its foot.

A third sleeping area is outboard of the saloon table, aft on the port side of the saloon. This is open plan to the saloon, with curtains for screening, with a generous 140x200cm rectangular bunk with space underneath for kit bags. It would make a great space for kids on passage.

For the charter market there’s also an option to drop the saloon table to create an additional double berth, plus small single cabins forward in the amas that are accessed from the foredeck, making a potential maximum of 10 berths.

Few owners are likely to want to sail with that many for long, but the flexibility of being able to cater for extra short term guests, without dragging the weight and volume of spare bedrooms around the rest of the time has an obvious appeal.

Given the price of the Neel 43 compared to other multihulls of a similar length it should not be a surprise that it has been conceived to be quick and easy to build, aside from the vacuum infused mouldings that are an important element in keeping weight to a minimum.

Those who love traditional joinery with hand crafted solid hardwood trim will be disappointed and the lack of a second heads will rule the boat out for some.

However, in general the relatively Spartan level of fit out Neel has opted for is appropriate for a boat of this style that’s aimed at a mass audience.

It took Neel 10 years to build its first 100 boats. In the current financial year, ending September, the yard has produced more than 30 boats across a four model range of 43-65ft sailing designs, plus semi-custom fuel efficient power trimarans.

The popularity of the Neel 43 means output is set to grow by a large margin in the coming year.

There’s much to like about this design: it’s a cruising boat in every respect, not an outright speed machine, yet it’s one that will quickly leave the competition behind. While it’s not a model that will suit everyone, founder Eric Bruneel has a good understanding of how a vast proportion of owners use their vessels and has created a yacht that will exceed their expectations in many respects. A decade ago trimarans were a niche part of the cruising world, however, the Neel 43 shows the concept of a cruising tri is ready for the mass market. The design has already proved hugely popular and one boat is leaving the factory every fortnight.

Catamaran vs Monohull: Pros, Cons & Main Differences

By: B.J. Porter Editor

The choice of catamaran vs monohull ultimately comes down to preference. What’s critical for one buyer may mean little to another. If your partner refuses to set foot on a boat which heels, that’s a deal-breaker for a monohull. But if you’re passionate about classic looks and styling, your quest for beauty may override other considerations and rule out catamarans.

We can’t tell you whether a catamaran or a monohull is right for you. But we can help you with the pros and cons of each for your search.

The Strengths and Pros

No matter your choice of monohull or catamaran, there are safe, comfortable, and excellent sailing boats of both types. Neither has an exclusive lock on any strength, and both sail safely and comfortably. But there’s a different emphasis on how they do it. No matter what you are trying to do – sail fast, cruise the world, or just host a crowd at the dock, there are monohulls and catamarans that can work for any requirement.

Catamaran advantages

Space and comfort: Two hulls and a wide beam make a very stable platform with lots of volume in the saloon and cockpit. Most living space is above the waterline, with wonderful light and airflow. Cabins in the hulls offer better privacy and isolation, usually with standing headroom.

Straight line speed: Most catamarans are faster in straight-line sailing speed (1) that similar sized or even longer monohulls. Without a lead keel, they’re lighter, so more driving force from the sails converts to speed, and narrower hull forms may have less drag than wide hulls with deep keels. Some heavier cruising catamarans may not be faster, especially if they keep rig size small for ease of handling.

Stability : The beam of two hulls with a bridge deck leads to much higher stability and resistance to roll (2). Waves in an anchorage that induce violent roll in a monohull may make a catamaran bounce or bob. Under sail, catamarans do not heel appreciably even when powered up.

Twin engines. : With one engine in forward and balanced in reverse, most catamarans can spin in a circle in place and make sharp adjustments to the boat’s direction. If you have an engine failure, you also have a second engine, giving a safety edge when you can’t sail. 

Monohull advantages

Upwind sailing performance: While catamarans have the edge at straight-line speed, monohulls sail closer to the wind. When you’re racing or you have to sail upwind to get to the next island, this can get you there faster.

Sailing feel and responsiveness : The “feel” of sailing a monohull is much better. With a single hull, you’ll feel wind pressure and trim adjustments immediately for a more responsive helm and a better ability to sail to the wind.

Maneuvering under sail: Monohulls are quite nimble tacking and turning under sail, and there’s less risk of slow or missed tacks.

Righting Moment: The primary offshore safety argument for monohulls is their ability to right when capsized. The heavy keel keeps the boat deck up when sailing, and most monohulls will come back upright even after a complete capsize.

Cargo and Loading: A higher displacement boat with thousands of pounds of lead hung from the bottom isn’t going to be as affected by loading as a relatively light multihull.

Aesthetics: This is subjective, as many catamaran enthusiasts love how they look. Classic sailboat styling, with swept sleek looks, springy sheer lines, and all the “right” proportions are more common on monohulls.

Weaknesses and Cons

Like strengths, weaknesses are relative; just because one class has a strength doesn’t mean the other doesn’t. There are spacious monohulls and beautiful catamarans, just like there are cramped catamarans and unattractive monohulls. The differences have to be highlighted relative to each other, and the weaknesses of one are most apparent compared to the strengths of the other.

Catamaran Cons

Upwind performance: Cats don’t sail as close to the wind, but they make up for it by sailing faster off the wind. You’ll sail a less direct course upwind. Even if you get in at the same time, you’ll have to sail farther.

Less responsive sailing: Two hulls with two rudders and a very broad platform reduce the helm feel when sailing, cutting responsiveness sailing in shifting wind and wave conditions. It also makes tacking slower.

No-flip zone: It is very difficult, but not impossible, to flip a large catamaran (3). But if a catamaran capsizes, it will not flip back over by itself.

Large in marina/close quarters: You have two problems in marinas. Beamy cats are tough to maneuver in tight spaces because they’re big and visibility is tough over the hulls. And many marinas charge extra because the wide beam extends into the next slip. The good news is that twin engines make tight maneuvering easier.

Price point: Catamarans are more difficult to build and need more materials. This is directly reflected in the cost of the boats.

Monohull Cons

They are heavier: Every large monohull needs a keel for stability (4). They can not sail or stay upright without thousands of pounds of ballast, and this makes them heavier and slows them down. Tiny monohulls can use a centerboard or daggerboard for stability, but most boats big enough to sleep on need ballast.

Darker interiors : Most monohull living space is lower in the boat, where you can’t put enormous windows for light and circulation. It’s very hard to get space as bright and airy as catamaran saloons.

Less living space: With one hull and no bridge deck saloon, most monohulls feel cramped compared to spacious catamarans.

More prone to rolling motions : Only one hull makes monohulls susceptible to rolling in waves, and the movement can be quite uncomfortable.

Heeling: Tipping is just part of sailing monohulls upwind and is unavoidable. It can be reduced on some other points of sail, but not eliminated. Many people, especially non-sailors and new sailors, find this movement uncomfortable or distressing.

Monohulls vs multihulls - why we think multihulls are better.

From time to time we hear the question asked:   What’s the difference between monohull and multihull sailboats anyway?   Aside from the obvious difference in the number of hulls, there are several very real ways in which monohull and multihull sailboats provide unique sailing experiences. As the makers of trimarans in particular, we here at WindRider admit we may be a   little biased – but let us show you why, to us, multihulls win every time.

Because of the stability having two or more hulls creates, catamarans and trimarans are noticeably more level than comparable monohulls when sailing. Even when powered up, multihull sailboats will rarely heel more than 5-10 degrees before it’s time to reef, compared to monohulls which can often reach up to 20+ degrees at high speeds. For a more relaxing and comfortable sail in terms of stability, multihulls win out over monohulls easily.

An added benefit of multihulls gaining their stability from the beam and hulls is that there is no need for ballast or a substantial keel – so exploring shallow waters that may be off-limits to monohulls is no problem for a cat or tri. You can even pull your multihull right up onto that perfect beach if you want with very little difficulty – try that with a monohull and, well, good luck.

Speed/Performance

If speed is what you’re looking for, monohulls have nothing on multihulls. Cruising catamarans are typically 25-30% faster than a cruising monohull of the same length, while trimarans can regularly   double   monohull sailing speeds on nearly any point of sail. Of course, these comparisons change a fair amount when the boats are loaded for cruising. Monohulls are much less affected by load than catamarans and trimarans and can maintain much of their performance when loaded for cruising, whereas multihulls are much more sensitive to load and experience reduced speeds when weighed down.

The speed of multihulls also serves as a valuable safety feature. With decent weather information, it’s relatively easy in a cat or tri to simply sail around rough weather to avoid it altogether. A slower monohull may have a bit more trouble doing the same.

Though it’s true that any boat – mono or multihull – can capsize in rough enough conditions, the fact is that it’s much more difficult to flip a catamaran or trimaran than it is to flip any monohull. It takes very high winds, too much sail, and large breaking waves to flip a modern cruising cat or tri.  Large ballasted monohulls are not only easier to capsize, but once they have, they’re much more likely to end up on the bottom of the sea with the crew bobbing in the water. When you compare this to a cat or tri that is much more likely to stay afloat as a big liferaft and spotting target (whether upright or not), there’s no question of which situation you’d rather be in.

Living Space

As far as living aboard goes, catamarans and trimarans vary a bit more than on other subjects. Catamarans, with their two widely-spaced hulls, are ideal live-aboard crafts as they typically have space below equivalent to a monohull 10+ feet larger. When combined with added cockpit space, possibly a flybridge, and more than doubling the deck space, it becomes a whole different ball game. Trimarans, on the other hand, generally have a bit   less   space below when compared to monohulls of the same length. Though they do provide additional storage in the amas and added net space that may make up for some of the small size, the fact is that trimarans are always going to have smaller living spaces than monohulls of the same length, and catamarans reign supreme in this category by a long shot.

Catamaran vs Monohull - 6 Points To Consider Before Choosing Your Boat

Multihull or monohull? It’s an age-old (and ongoing) debate, and each option certainly comes with its own set of pros and cons. Whether you’re thinking of investing in a boat of your own, or planning on chartering one for a sailing holiday, one thing’s for sure: the type of vessel you select will have an impact on your cruising experience. Ultimately, what you intend to use it for will determine which type of boat would be best suited for the job. In this article, we considered the aspects of space & design; safety; stability; speed; manoeuvrability and cost, so do read on for our comparison of the multihull catamaran vs the monohull sailboat.

THE CATAMARAN VS THE MONOHULL – A COMPARISON

1. stability . which is more stable, a catamaran or a monohull.

Fact – by virtue of having two hulls, both under sail and at anchor, catamarans are more stable than monohull boats. If you are sailing with young children, seniors – or anyone who’s not all-too steady on their feet – a catamaran will provide you with a much smoother and stable cruising experience than a monohull. Being multihulled, catamarans are not nearly as susceptible to the action of the ocean’s waves. This prevents them from heeling as much as monohull vessels would under the same conditions. As anyone who suffers from seasickness will tell you, this can be an enormous bonus. What’s more, a cat’s multihull stability will also be highly appreciated by anyone prepping food in its galley (two hulls make for a somewhat more pleasant dining experience, too). Lastly, because of its superior stability, walking around the deck (and moving around the interior) of a catamaran is much easier than it would be on a monohull. The verdict? Catamarans are more stable than monohulls.

2. SAFETY . WHICH IS SAFER – A CATAMARAN OR A MONOHULL?

The inherent stability and natural buoyancy of a catamaran automatically increase its safety while out at sea. As catamarans don’t have heavy, lead-loaded keels, they will remain afloat, even when (heaven forbid) they are holed. This is because most modern catamarans have such a large amount of buoyancy built into them that they are almost unsinkable, making them much safer than monohull sailboats in this regard. Sure, catamarans can capsize, but being rescued from an upside-down, still-floating multihull is definitely preferable to sinking to the bottom in a monohull! The verdict? Contemporary catamarans are incredibly buoyant and virtually unsinkable, making them safer than monohull sailboats.

3. SPACE & DESIGN . WHICH IS MORE SPACIOUS AND PRACTICAL – A CATAMARAN OR A MONOHULL?

Due to the boat's shape (and the amount of usable space each design allows), when compared square-foot-for-square-foot, every area of a monohull vessel is usually smaller than its catamaran counterpart. Generally, catamarans offer more room to move in its galley, cockpit and saloon areas than similarly priced monohull boats. Often, catamaran cabins are more spacious too, with cabins of even the smallest cat offering stand-up headroom. Catamarans are also generally more private than monohulls, and more straightforward when it comes to separating living spaces. This can be a significant advantage when you are cruising with children or guests. As most of a cat’s living spaces are above the waterline (on a monohull, only the cockpit is above the waterline), you’ll also enjoy superior airflow through ventilation on a catamaran. If you’re a scuba-diving enthusiast, carrying all of your diving equipment will be easier on a cat. What’s more, catamarans have trampolines, which make them perfect for onboard sunbathing as well as stargazing in the moonlight – a big, romantic plus for sure! Catamarans also have shallower drafts, allowing you to drop anchor closer to the beach than a monohull would. The verdict? Compared square-foot-for-square-foot, catamarans are more spacious than their monohull counterparts. In terms of design, a catamaran is perfect for onboard sunbathing and stargazing and will allow you to anchor closer to shore.

4. MANOEUVRABILITY . WHICH IS EASIER TO STEER, A CATAMARAN OR A MONOHULL?

Most catamarans can turn 360 degrees within their own length, something very few monohulls are capable of doing. However, generally speaking, monohulls are quick to tack, more manoeuvrable, and quicker to respond to the helm than catamarans. At the helm of a catamaran, you’ll get less feedback from the wheel than you would from a monohull. This will require you to be vigilant in rough conditions, and you’ll also have to know when to reduce sail. Compared square-foot-for-square-foot, catamarans are much lighter than monohulls, which means they also slow down a lot quicker. For the most part, catamarans are easier to dock than monohulls, as they have two motors and two rudders which simplify things a lot. This also does away with the need for a bow thruster. The verdict? We’re calling it a tie. Although monohulls are generally more manoeuvrable than catamarans, thanks to their two motors and two rudders, cats are easier to steer than monohulls.

5. SPEED . WHICH IS FASTER, A CATAMARAN OR A MONOHULL?

Although catamarans cannot sail as close to the wind as monohull sailboats, most cats do sail faster than a monohull on a reach. On downwind runs, reaches, and broad reaches, in particular, catamarans usually beat monohulls when it comes to speed, going about 20% faster than a monohull (even outrunning bad weather when necessary!). Another plus is that sailing a catamaran requires less physical exertion than sailing a monohull. The verdict? Even if they don’t point as high into the wind, catamarans are faster than their monohull counterparts.

6. COST . WHICH IS MORE EXPENSIVE, A CATAMARAN OR A MONOHULL?

Generally speaking, catamarans with similar sleeping capacity and equipment are more costly than their monohull counterparts (both to own or to charter). Just keep in mind that catamarans typically hold their value better and longer (and tend to be in higher demand) than monohulls. Comparatively, previously owned monohulls are cheaper to purchase than cats, as supply tends to outweigh demand by a large margin. The verdict? Catamarans are more costly than monohull sailboats. However, a read-through of Points 1 to 5 might convince you that they are worth the extra expense.

CATAMARAN OR MONOHULL? – YOUR NEEDS WILL DETERMINE YOUR CHOICE

Looking at the list of pros and cons above, it would seem that the catamaran comes out the clear winner – at least when judged on aspects of safety, space & design, speed and stability. However, your budget, the requirements of the people in your sailing group, as well as your own needs and preferences will all play a significant role in the boat you end up choosing. Both catamarans and monohulls offer unique advantages, and whichever choice you go with, we wish you many happy ocean voyages and an abundance of adventure! Ps. If you’re still unsure which option is the right one for you, why not check out the verdict from ocean adventurers who have lived aboard two monohulls and four catamarans over the past 25 years?

Catamaran vs. Monohull: We Changed, Should You?

There are two schools of thought when it comes to monohull versus catamaran . We have done extensive cruising and lived aboard two monohulls and four catamarans over the past 25+ years . We experienced the good and the bad for both single hull and multihulls first hand. Quite honestly, the pluses for catamarans far outweigh the minuses. There are multiple benefits of catamarans. They are faster, more stable and spacious, and have shallower drafts allowing safer anchorage closer to shore. Being on a stable platform with no heeling cuts down on crew fatigue and seasickness leaving the crew more alert and in control of the vessel. Even novice sailors feel more confident on catamarans.

When we built our monohull Royal Salute in the early 90s, catamarans were not established and were looked upon with extreme suspicion by most cruisers, including ourselves. “Safety and the capsize” issue were always the first things to come up against sailing catamarans. It is a fact that monohulls can get rolled in heavy seas but will right themselves because of the heavy lead keel, and while crew and vessel will be battered, the roll is survivable.

However a catamaran once capsized, will remain upside down (jokingly referring to this state of the catamaran as “reaching its most stable position when upside down”). The inability of a catamaran to self-right was and still is a major bone of contention. However, what is not often discussed is that a monohull has about a 5,000 pound keel of lead that is constantly trying to drag the boat to the bottom of the ocean versus a catamaran that has no ballast and is in most cases with modern catamarans, unsinkable.

So the options are to either sail the world on a boat that, if it springs a leak, will sink like a stone or a vessel that cannot self-right in the event of a capsize but will not sink no matter what. So from a practical point of view, here are our observations over the last 25+ years of living aboard, on the advantages and disadvantages of a catamaran.

ADVANTAGES OF A CATAMARAN

1. speed equals safety.

The speed of a catamaran makes it possible to outrun bad weather. While catamarans do not point as high into the wind as a monohull (or if it does, it makes more leeway or slides sideways), it is about 20% faster than a monohull. This means that even if you sail upwind at a slightly wider angle to the wind than a monohull and have to cover more distance, you will still arrive at your destination long before a monohull.

A modern performance catamaran with daggerboards and good quality sails will point as high as a similar sized monohull. It will point the same as a comparable monohull and sail much faster and therefore arrive at an upwind position much sooner than a the monohull. It is important to note that most of the production catamarans on the market are under-powered and are equipped with standard smaller sails. In lighter breezes many of these designs perform poorly unless fitted with bigger headsails, a Code Zero and a square-top mainsail.

While we believe that more comfortable and safer in rough weather , we have to concede that when the weather gets really bad (60 knots of wind or more) we would personally prefer to be on a monohull from the standpoint of surviving. I would say that a monohull is preferable for serious offshore single-handed sailing because you can more easily hove-to in a monohull. We have been in some extreme weather on a number of catamarans and never really felt that we were in danger, although it takes some nifty seamanship.

A monohull could capsize in extreme weather or even roll in a storm, but they generally come back upright. A catamaran on the other hand, will not right itself. But the cat will generally stay afloat, offering a good place to survive while you wait out the storm or until help comes along. Well-designed modern catamarans are very hard to capsize though.

Having said all that, most catamarans can do 200 to 250 miles a day and with modern technology allowing one to pull down weather at will, there is no good reason why you should get caught in extreme weather. A faster boat is a safer boat as it will in many cases be able to outrun bad weather. With good weather routing information a catamaran can avoid most serious weather and, at worst, place itself in the most favorable position to avoid the brunt of a storm.

2. A Catamaran is a Stable, Safe Platform Underway

Catamarans have no ballast in the keels like monohulls do and therefor it relies on beam and buoyancy for stability. Typically cruising catamarans will have a beam to length ratio of roughly 50%, although many designs nowadays exceed the 50% rule of thumb. So, a 45-ft long catamaran will be about 22-ft wide, providing a very stable platform when sailing. Unlike catamarans, monohulls cannot overcome the rolling and pitching with their narrow beam and the lead ballast for stability.

This rolling and pitching makes the deck on a monohull very unsafe whereas on walking around on the deck of a catamaran while underway is far easier since the boat is much more stable, and it doesn’t heel. This makes sail changes and reefing much easier and a lot safer for the crew. Without the rolling and pitching motion, the danger of falling overboard on a catamaran is considerably less than on a monohull.

3. Crew Fatigue Reduces on a Catamaran

Because a catamaran does not heel over like a monohull, it offers far more comfort underway because the motion is mostly fore and aft pitching and very little beam-to-beam rolling. On all points of sail, a catamaran tracks upright and significantly reduces crew fatigue and seasickness. Seasickness is usually caused by things like anxiety, fatigue, hunger and cold, which all add to a sense of disorientation. This leads the crew to making bad decisions and seamanship errors that could be fatal to the crew and vessel. The more stable platform of the catamaran will hugely keep those issues at bay, making the crew more alert and energized.

Every action and chore including cooking is much easier on a catamaran when underway. It is much more pleasant to be on the deck level looking out rather than being stuck “down below.” It is also much nicer to sleep on a boat that doesn’t heel. I remember nights at sea in our monohull when I was rolling around in my bunk unless I was properly wedge in a little corner. That is simply not the case on catamarans.

All these factors ensure that your crew will not expend unnecessary energy to simply try and stay upright, onboard and safe on a long passage. Your crew on a catamaran will be well rested and alert and will be able to function well if a stressful situation arises.

4. Comfort at Anchor

Catamarans provide a wide platform and therefore offer lovely spaces to relax at anchor without the rolling motion that monohulls have a tendency to do in a swell. During our 15 years of cruising on a monohull, we have often had to leave anchorages that we really were not finished exploring because of a rolly, uncomfortable anchorage. Big rollers or swells coming into an anchorage can make conditions in an anchorage very uncomfortable and unsafe.

We were anchored off Funchal on the island of Madeira in our monohull Royal Salute once, when we were forced to leave our anchorage. The rolling became so bad, we were rolling from gunnel to gunnel. The anchorage became untenable to remain anchored, forcing us to go out to sea in foul weather in the middle of the night. This is an extreme case but believe me, we have left many an idyllic anchorage because of a rolling swell into the anchorage. Catamarans, on the other hand, do not roll from like monohulls have a tendency to do and are far more comfortable at anchor.

5. Anchor Bridal Setup

Catamarans are fitted with a bridle, attached to both bows and down to the anchor chain, resulting in a very stable position at anchor. What we found with our monohull was that because the bow acts as a sail (because of the high freeboard), the boat tended to sail at anchor in high winds. It sailed in one direction until the chain snatched and tacked over and sailed in the other direction, feeling like it might dislodge the anchor altogether. The catamaran on the other hand sits at anchor a lot more stable and doesn’t sail around as much.

6. Ease of Boarding on a Catamaran

Thank goodness we were much younger and more agile during our monohull days. Royal Salute and most monohulls of her generation or older, have high free-boards, making it quite a feat to get onto the boat from the dinghy. It was one of the most challenging things to do because unlike the more modern monohulls that have a scoop at the back, we had to climb up on the side of the boat to get on and off. We, of course rigged steps, etc. but it was always a hassle compared to the ease of getting on and off a catamaran from a dingy or from the water.

7. Shallow Draft Equals Better Anchorages

Catamarans have significantly shallower drafts than monohulls, allowing for safer anchorages closer to shore. Most catamarans in the 40-ft to 50-ft range draw between 3-ft to 4.5-ft, so they can anchor in places that a monohulls can not even consider. In the shallow waters of the Bahamas for example, the catamarans have a big advantage. We often anchor our own catamaran just a few feet away from a beach. It definitely allows one to be able to explore areas where the water is shallow without the fear of running aground.

The shallow draft also allows for emergency repairs in shallow water and even doing the bottom job when the tide goes out as we have done in places like Mtwapa Creek in Kenya, East Africa. The catamaran easily rests on her keels on the sand without help making it a breeze to do the “annual haul out” even in remote locations.

8. Dinghy Davits & Dinghy Size

All catamarans have a set of davits that make it very easy to raise and lower the dingy. Our monohull and most cruising monohulls do not have an efficient or easily accessible set of davits. This makes raising and lowering the dingy an elaborate production. Catamarans on the other hand, has davits systems easily accessible and some even have platforms to rest the dinghy on.

The lack of beam and difficulty of lifting the dinghy also limits the size and type of dingy that one can reasonably carry on a monohull. As we all know, the dingy is your transport to and from shore and diving or fishing spots, so the bigger and faster the dingy, the better off you are. A catamaran can carry both a heavier and bigger dinghy which makes the popular center consul dinghy so much more possible.

9. Interior Space and Comfort on a Catamaran

We sailed 32,000 NM on our 45-ft monohull, happy as clams, not realizing that sailing does not have to be done lying on your ear 24/7 while on passage or sitting knee-to-knee in the cockpit at anchor with your two other guests at the dinner table! One can liken sitting in a monohull cockpit to sitting in an empty Jacuzzi, you are always nice and close to the other folks.

Now that we are on our fourth catamaran, there are a few things that have become more evident to us than the incredible space and comfort of a catamaran, not only at anchor but also underway. The cockpit and living space in general are huge compared to a monohull, making for very comfortable and spacious living conditions. It feels more like you are at home, rather than just on a camping trip.

Knowing that one spends at least 90% of one’s cruising life at anchor, it’s important to have good open living space, which most modern cats nowadays offer. A lot of cats have walk around beds, lots of storage, every modern appliance including washer/dryer, etc. However, one has to fight the urge to fill the space if you want to keep the cat light and fast.

Sailing with guests onboard for extended periods of time, in close quarters can become claustrophobic but on a catamaran people are spread out and separated. With guests sleeping in one hull and the owners in another, catamarans offer much more privacy and separation. Some cats even have privacy doors that will close off the entire hull and has a separate entrance onto the deck, which really separates you from the guests completely.

There is very little heeling on a catamaran, so there is no need for hand grips and safety harnesses inside the boat. There is nothing better (and safer) than being able to walk from the cockpit into the living room (saloon) on one level or one step down at most. In a monohull, when heeling at a severe angle, you would have to claw your way from the companionway steps down to the living area, while fighting to stay upright, significantly tapping your energy.

Unless you hit extreme conditions, everything stays put on a catamaran reducing the anxiety before doing passages of having to stow and secure everything. This very issue makes a lot of cruisers reluctant to weigh anchor and explore more often. It is just too much effort to pack away all your stuff once comfortable in an anchorage!

One thing you will notice is that the stove on catamarans are not gimbaled like it is on monohulls and this should tell the story in itself. The stability and comfort on a catamaran is far superior. Cooking is easy and safer. I often open a nice cold beer, put it down to do something and forget about it only to find a warm beer later in the same place I left it. This is not something that happens on a monohull.     

10. Redundancy on a Catamaran

Unlike monohulls, catamarans have a lot of critical redundancies. That of course means two hulls to clean and anti-foul, double the engine maintenance, etc. but having two of the critical equipment like engines for instance, outweighs the downside.

With two engines, if one fails you still have adequate propulsion to go anywhere. If by some fluke the second engine also fails, you have a full set of spares to fix at least one of them. Our friends once hit a sleeping whale off Tanzania, and when it dove, it hit the prop, bending it. They limped into the narrow channel on the one engine but at least they could make it to a safe harbor where we surveyed and repaired their damage.

We often only use one engine when motoring while making passage in order to conserve our fuel. The one engine is totally capable of moving the boat along at a good speed unless you are in heavy seas and you may need more power. Other than that we only use two engines to dock or maneuver the boat in close quarters.

Because there are two engines there are also two independent charging systems via the alternator on each engine. If one alternator goes out, there is still another complete charging system. There are two rudders and if one fails or falls off (as has happened to our friends on a monohull off Columbia, where they almost lost their boat) you have a second rudder that is completely capable of steering the boat by itself indefinitely. That holds true for several things on a catamaran!     

11. Maneuverability

The engines are spaced far apart on a catamaran and it makes maneuvering much easier and more precise than monohulls, unless the monohull has a bow thruster. We did not have a bow thruster (not many monohulls do) and had to rely on prop-walk and using prop wash on the rudder. A modern catamaran can do a 360 turn on her own axis. A monohull cannot do this and have a bigger turning circle. However, a monohull under sail is much more maneuverable and certainly will tack a lot faster than a catamaran. The ease in maneuverability under engine on a catamaran in close quarters specifically, is vastly superior comparatively.

12. Rigging

Because of the beam on a catamaran the spinnaker pole has become unnecessary equipment. Hallelujah, I say. That pole on our monohull was a pain the behind and I always hated having to use it. On a catamaran, one can fly an asymmetrical cruising chute or spinnaker, using the bows to tack the clew or run a guy through a block so it is very much simplified, easier and safer.We also sail wing-on-wing with twin headsails when we sail downwind. We use our furling jib and furling Code Zero. It is as easy as one, two, three.

DISADVANTAGES OF A CATAMARAN

1. bridgedeck slamming.

One advantage most monohulls do have when underway is that they don’t slam. Catamarans with a low bridgedeck clearance can experience significant slamming in confused seas sailing upwind. This slamming can be quite disconcerting when you first experience it as we did on a Shuttleworth 44 design, our first ever catamaran experience, 20+ years ago. At times, it felt as though the boat was falling apart. Of course the boat was fine but nevertheless, the stress on the crew from the constant noise and discomfort was significant.

Monohulls don’t have a bridgedeck which means no slamming and are therefore a bit more comfortable than l ow bridgedeck catamarans when beating into severe confused conditions or “washing machine” conditions as we call it. Modern catamarans mostly have better bridgedeck clearance and the slamming is significantly less. However, not all cats have a good clear tunnel under the bridgedeck. Some manufacturers build beds into the bridge deck in order to make more space in the chest of the catamaran where the slamming occurs. These protuberances into the bridgedeck tunnel will likely increase slamming. So be mindful of that when selecting a catamaran. We currently own a Bali 5.4 and the bridgedeck clearance on this boat is more than adequate and the tunnel is clear. We therefor experience very little slamming compared to our Prout 45 that we previously owned (picture of sister ship below) with a much lower bridgedeck.

We Explain Bridgedeck Clearance

In the pictures below, the Bali 5.4 has very good clearance from the water to the bridgedeck and has a nice clean tunnel versus the very low bridgedeck of the Sunreef 50. 

2. Sailing Downwind

Monohull spreaders are set at 90 degrees to the mast whereas a catamaran has to have backswept spreaders. The reason is that, on a monohull, there is a backstay and using this, plus the intermediates you can get a nice pre-bend in the mast (the pre-bend is to flatten out the main sail and allow for better performance).

On a catamaran with no back stay, you need to use the back swept spreaders and the diamonds to pre-bend the mast. The reason I point this out is because on a catamaran, if you want to broad reach or run, the mainsail cannot be let out all the way because the backswept spreader tips could punch holes in the fabric.

On a monohull, the spreaders are at 90 degrees so you can let the main and the boom out much further which is, of course, much more effective. This is one of the reasons it is better to broad reach and tack downwind on a catamaran.

Whether a monohull or multihull, sailing dead downwind doesn’t usually make great VMG. Therefor a regular cruising cat, much like a monohull, needs a lot of sail area and has to sail deep downwind if it is to achieve a decent speed made good (VMG). This video demonstrates how we achieve this by sailing wing-on-wing downwind.

It is more difficult to find a dock either as a transient or a permanent slip for a catamaran in general because of the wide beam. But this is changing fast and will soon not be too much of an issue. In the USA dockage is charged by the length of the boat in feet, so there is no disadvantage there but, in some places, (the Mediterranean for example), dockage is charged at length times one and a half because of the additional beam.

Since the catamaran is stable at anchor, we mostly anchor out. We have more privacy, a better breeze and usually a stunning view.We have a nice dinghy with a good outboard engine and is big and comfortable enough to get to shore fast and together with the modern conveniences like the generator, watermaker and washer/dryer, docking becomes a non-issue.

It is definitely more difficult to find a travel lift with enough beam for a catamaran for a haulout, while, for a monohull, there are absolutely no problems anywhere. The wide beam of cats also greatly limits the number of shipyards that can haul them out. Most catamarans over 40-ft must be hauled out with a 50-ton travel lift. This not only increases the cost of the haulout, but greatly limits the choice of the shipyards for repairs and maintenance. With limited choice, prices are high for shipyard services.

Catamarans do tend to have a lot more windage than monohulls. This can be an issue especially when maneuvering in close quarters with a strong wind. But I have found that, provided the engines are powerful enough for the size of catamaran, that twin engines negate this problem. Also, many modern large catamarans now have a bow thruster fitted. It is super easy to dock.

The cost of getting into a catamaran is much higher than that of monohulls. That could put a serious dent in your cruising kitty or require you to put your dream on hold a little longer. Pre-owned monohulls on the other hand are very cheap to buy comparatively, because the supply presently far outweighs the demand.

Catamarans are in high demand and they typically hold their value much better and longer and the trend is now heavily in favor of the catamaran market. When prospective buyers contact us for catamarans under $250,000 the choices are very limited and catamarans under $100,000 is near impossible to buy. In this case, your best bet is to go with a monohull unless you go with much older boats like the Prouts or the less expensive Geminis.

Our Own Catamarans & Monohulls

FYI: Royal Salute , a Bruce Roberts 45 monohull, was the first boat we owned and sailed approx. 30,000NM on. Mythral, a Seafarer 30, was our “toy boat” while we were waiting for our catamaran to be built. Even though this classic little monohull sailed around the world, it didn’t have much in modern conveniences like running water. Siyaya was an Island Spirit 40 catamaran that we sailed from Cape Town to Florida on and then taught live-aboard sailing classes for several years. Zuri I was a Prout 45, a beautifully crafted catamaran but by today’s standards is considered old technology. Our Lagoon 450 SporTop ( Zuri II ) is a fantastic live-aboard catamaran. We lived and taught aboard her for three years but sold her last year and we currently own a Bali 5.4 ( Zuri III or Z3 as we call her now). Read about our various boats .

CONCLUSION: CATAMARAN vs MONOHULL

We were dyed in the wool monohull sailors for 15+ years. We loved the pretty lines of monohulls, the sailing ability and what we believed at the time to be much safer vessels. However, now that we have been avid catamaran enthusiasts, we simply can never go back to monohulls. Catamarans have come of age and with modern technology have overcome most objections that sailors of old had against them. They are well designed and built, are safe, and we simply love that they sail fast and upright. There is not a whole lot to dislike about a catamaran when you live aboard. We have weighed all the pros and cons of catamarans and found that the pros far exceed the cons. We made the change to a catamaran and do not regret it one bit!

We hope that this article will clear things up for all the prospective catamaran owners out there.

4 thoughts on “Catamaran vs. Monohull: We Changed, Should You?”

I read that the engineering on the catamarans were improved over the years. Whats the oldest year would you recommend designwise?

Scott, my apologies for the late reply. We’ve been traveling in Africa. Anyway, catamarans have come a long way and improvements in technology is happening at lightning speed. I reckon that even the older model catamarans are good. It depends on what your needs are. If you want something a little better performance wise, I would go for something no older than 15 years.

After buying a catamaran what is the difference in expense of a catamaran vs a monohull. Many articles state that not only the initial cost of a catamaran is more it the operating cost as well.

Hi Todd, it is more expensive. The annual dockage and haul out as well as maintenance will be more expensive. You obviously have two engines to maintain and various other pieces of equipment to service in both hulls. While there is more equipment there is also more redundancy and of course you have the comfort factor. So, depending on your situation, it’s probably worth it.

The Sailboat Debate: Monohull Vs Multihull

It is a question that we hear time and time again. Which is best: multihulls or monohulls? Is a catamaran faster than a monohull? Apart from the number of hulls, what are the main differences between the two? The choice is an important one because it has all kinds of consequences for speed, handling, comfort and safety. To make sure your choice of new boat lives up to your dreams, you first need to understand the basics and find out what makes cruising monohulls and multihulls tick:

A monohull has just the one hull and displaces its volume in water. Monohulls have a keel underneath their hulls which is generally very heavy (made of lead). This ensures that when a monohull heels over, once the pressure is removed from the sails, the boat rights itself using gravity. There is no doubt that a well-built monohull can be a beautiful and extremely sound boat. Their sleek lines look fantastic on the water and they offer an exhilarating sailing experience. Monohulls tend to preferred by ‘purist sailors’ – those who enjoy traditional sailing and the thrill of heeling over when underway.

Multihulls:

Multihulls have either two hulls (catamarans) or three hulls (trimarans) and displace a smaller amount of water. This is due to both hulls being in the water with the main living areas located on the bridgedeck above, spreading the displacement of their weight over a larger area. Multihulls have become the leading choice of cruising sailors due to their combination of speed, onboard living space, performance, and safety.

But which one is right for you? To help you choose the right boat for your individual needs, we’ve compiled an overview of the main differences between comparatively sized cruising multihulls and monohulls:

SPEED: Due to their lighter weight, multihulls tend to be faster and can sail better in lighter winds. On average, a cruising catamaran or trimaran is around 25-30% speedier than a conventional monohull of an identical size. The only downside is that multihull vessels are only this fast if the load is relatively light. While you can get away with a cruising load on a monohull, the same weight has the tendency to slow a catamaran.

LIVING SPACE: Multihulls offer far more living space as well as more exterior space for safe and easy movement around the deck. As a guide, a 40-foot catamaran generally has the space of a 60-foot monohull.

STORAGE CAPACITY: Due to its extra hulls and wider living and cockpit areas, cruising multihulls tend to have greater storage space than monohulls. For long-haul cruising adventures, the extra storage of a multihull is extremely beneficial for accommodating additional supplies, safety gear, back-up parts, etc.

HEELING: When it comes to sailing, the biggest difference between a multihull and a conventional monohull is the lack of heeling. Cruising catamarans and trimarans do not heel over like a monohull when underway. Even when fully powered, a multihull is unlikely to heel more than 5-10 degrees. So, if you opt for a catamaran, there’ll be no more bracing awkwardly or spilling drinks when under sail!

ROLLING AT ANCHOR:  Multihulls do not get a rolling motion from swell when at anchor. Monohulls suffer from the pendulum effect in a windy anchorage, whereas catamarans sit flat on their two hulls offering greater comfort at anchor.

DRAFT:  Multihulls have a shallower draft than a similar-sized monohull, which enables them better access to inlets and lets them anchor much closer to beaches. This is particularly helpful when coastal cruising, as multihull sailors can enjoy more exploring and anchor out of uncomfortable wind and tidal conditions.

PROTECTION:  Most multihulls have overhead coverage to the cockpit area and helmstations, offering great protection from the fierce sun and rain while at sea and at anchor. Even in miserable drizzle, multihull sailors can enjoy the space and views while sitting in the cockpit.

MANOEVRABILITY:  Multihulls with two engines generally have better manoeuvrability than monohulls. With two engines set far apart it is possible to do a 360-degree turn in a very tight space. This is extremely handy in marinas in windy conditions. The extra windage the higher sides attract can be counteracted with the double screw engines. Two engines also add a safety element, as if something happens to one you always have the second engine as a backup.

SAFETY: Multihulls are also generally recognised as safer than monohulls for a range of reasons: Their speeds allow you to out-run bad weather. In the unlikely event a multihull capsizes, it stays afloat rather than sinking to the bottom of the ocean.

Monohull vs Catamaran: A Deep Dive into Design and Performance

The genesis of two designs.

In the world of sailing, the debate between monohulls and catamarans is a tale as old as time. The history of these two iconic designs stretches back to antiquity, reflecting the evolution of human innovation and our insatiable desire for exploration.

The monohull's genesis lies in the early days of human seafaring. Traditional cultures from the Mediterranean to the South Pacific have all used some form of monohull craft for fishing, trade, and exploration. The monohull's sleek, single-hulled design, characterized by a deep keel and distinct bow and stern, offers an efficient shape for cutting through waves. Over centuries, the monohull design has been refined and perfected, culminating in the magnificent yachts we see gracing our waters today.

On the other hand, the catamaran, a vessel with two parallel hulls, boasts a legacy equally steeped in seafaring history. Its origins can be traced back to the outrigger canoes used by ancient Austronesian cultures.

The word 'catamaran' itself is derived from the Tamil word 'kattumaram', which loosely translates to 'logs tied together'.

These innovative sailors discovered that by adding a second hull, they could greatly improve the stability and speed of their vessels, a design principle that holds true to this day.

Exploring the Monohull Design

Stepping into the present, let's delve deeper into the modern monohull design. Its traditional single hull offers a quintessential sailing experience that's hard to match. Monohulls are typically seen as the embodiment of the romantic sailing ideal, thanks to their elegance and the graceful way they heel under sail.

One of the major benefits of monohulls lies in their seaworthiness. Their deep keels provide excellent stability, allowing them to handle heavy seas and high winds effectively. In addition, the keel acts as a counterbalance, enabling the boat to right itself after being heeled over by a gust of wind. This 'self-righting' characteristic is a significant safety feature exclusive to monohulls, adding a level of reassurance when navigating challenging sea conditions.

Monohulls are also known for their responsive handling and satisfying sailing performance. The mono-hulled design cuts cleanly through waves, resulting in a smooth and predictable ride. If you're the type of sailor who enjoys feeling the wind and waves' raw power, the visceral connection that a monohull provides is unparalleled.

However, as with everything in life, monohulls also have their downsides. For one, space can be at a premium. The deep keel and the rounded hull shape necessary for stability and performance take up much of the interior volume, leaving less room for living space compared to a similarly sized catamaran.

Another consideration is the heeling motion. While some sailors love the feeling of a boat leaning into the wind, others may find it uncomfortable or disorienting, especially during prolonged passages.

Despite these trade-offs, monohulls continue to hold their charm for many, offering a blend of tradition, performance, and adventure that has stood the test of time. In the next part of this deep dive, we'll shift our focus to the twin-hulled wonder of the sailing world: the catamaran.

The Catamaran Conundrum

As we switch gears to catamarans, it becomes apparent how contrasting they are to their monohull counterparts. Catamarans, with their dual hulls connected by a central platform or cabin, present an entirely different set of strengths and challenges.

Let's start with one of the most prominent features of catamarans: their stability. The wide beam of a catamaran provides a significant increase in stability over a monohull, reducing the boat's tendency to roll. This stability not only enhances the comfort of your crew but also allows for safer and easier movement on deck and below. If the notion of preparing a meal in a level galley while underway appeals to you, a catamaran might be the perfect fit.

Space is another major advantage of catamarans. With essentially two hulls worth of volume, catamarans typically offer much more living space than a similarly sized monohull. This makes them an attractive option for those planning extended cruises or living aboard. The additional space also allows for separate, private cabins in each hull, perfect for accommodating families or groups.

When it comes to performance, catamarans have a distinct edge in certain areas. Their dual-hulled design and lack of a ballasted keel result in less drag, allowing them to often outpace monohulls in moderate conditions. However, this speed advantage may be offset in heavy weather, where the ability to cut through waves (rather than ride over them) can make a monohull's ride smoother and faster.

But, just like monohulls, catamarans aren't without their drawbacks. While their stability and flat sailing characteristics are often seen as benefits, they can also create a false sense of security, leading some sailors to push their boats beyond safe limits. Additionally, while catamarans are significantly harder to capsize than monohulls, if they do flip, they generally won't self-right like a monohull would.

Furthermore, catamarans can be more challenging to handle in confined spaces due to their wider beam. Docking, in particular, can be trickier, especially in marinas designed with narrower monohulls in mind. Also, the increased beam and dual hulls often lead to higher mooring and maintenance costs.

Monohull vs Catamaran: Performance Parameters

Before we take this deep dive to its conclusion, it's important to touch on a few key performance parameters. These can greatly influence whether a monohull or catamaran would be a better fit for your sailing needs.

For starters, how a boat handles various wind conditions is critical. Monohulls, due to their keeled design, tend to excel upwind. Their ability to 'point' into the wind is usually superior to that of a catamaran. On the other hand, catamarans, with their lighter weight and reduced drag, often have the upper hand in downwind and lighter wind conditions.

Another factor to consider is load carrying capacity. While catamarans have more space for storing gear and provisions, they can be more sensitive to overloading. Additional weight can significantly impact a catamaran's performance, whereas monohulls tend to be more forgiving in this regard.

In the final part of this blog, we'll wrap up our deep dive by considering these and other factors to help determine which design might be the best fit for your sailing needs.

Choosing Your Vessel: What Suits Your Sailing Style?

Now that we’ve explored the design principles and performance traits of monohulls and catamarans, it’s time to consider what kind of vessel will best cater to your personal sailing needs and preferences.

If your sailing plans involve long passages in open waters, especially in rougher seas or challenging wind conditions, a monohull's sturdy and seaworthy design might be the most fitting choice. Their excellent upwind performance and smoother ride in heavy weather will provide you with both comfort and safety on lengthy oceanic voyages.

For those attracted to the exhilaration of speed, catamarans, with their swift downwind capabilities, can offer a thrilling sailing experience. They can be the ideal choice if your sailing adventures are primarily focused on coastal cruising, island-hopping, or participating in sailing races where their speed advantage can shine.

Lifestyle preferences play an essential role as well. If you value space and comfort, and perhaps are contemplating living aboard or planning extended family cruises, the spacious interior of a catamaran, with its level sailing and private cabins, may be the superior option.

However, if you're a sailing purist who enjoys the classic feel of a boat that heels under sail, the thrill of mastering the art of balancing a boat in various wind conditions, a monohull will likely provide the sailing experience you're seeking.

As for cost considerations, remember that while catamarans offer more living space and stability, they can also come with higher purchase, maintenance, and mooring costs.

Closing Thoughts: Your Ideal Adventure on the Water

If you're looking to buy or charter a sailboat , the choice between a monohull and a catamaran ultimately boils down to your sailing goals, personal preferences, and budget. There's no definitive answer to which is better because it's subjective to the individual sailor.

Whether you're lured by the traditional appeal and seaworthiness of a monohull or the comfort, stability, and speed of a catamaran, the most important thing is to choose a vessel that will provide you with many memorable and safe adventures on the water.

At Sailing Virgins , we love them both and appreciate their unique characteristics. Whatever you choose, the sea will always be an ever-changing playground that continually challenges and rewards those who embrace the sailing lifestyle.

Monohulls or Catamarans – Which is Best for the Cruising Sailor?

The debate between catamarans vs monohulls still rages, and most boaters are firmly on one side or the other. The truth is, either a catamaran or a monohull can provide a wonderful way to enjoy sailing, traveling, and being on the water. 

Both have advantages and disadvantages, and both have large and loud fan clubs. The choice between a catamaran and a monohull depends on your budget, lifestyle, and personal preferences.

My wife and I have owned both types of vessels over the years. After five years of cruising on a Lagoon catamaran, we decided to go old school and bought our current boat—a heavy, full-keel monohull. The catamaran was fun, for sure—but it wasn’t for us in the end. Here’s a look at all of the differences we learned about during our journey.

At anchor, a catamaran provides superb comfort and living space. The “upstairs” cockpit and salon mean that boaters can enjoy non-stop wrap-around views.  Monohull boaters are stuck in their caves and must peek out of their small portlights or climb into their cockpits to view the world. 

A modern catamaran will also have swim steps that make it easy to get on and off the boat and provide easy access to dinghies and water toys. 

If there’s an uncomfortable roll or swell in the anchorage, the catamaran’s stability will make the roll a bit less noticeable. Monohull boaters are more likely to be adversely impacted in a rolly anchorage. This does not mean that the cat owners are getting a perfect night’s sleep every evening, however. Catamarans just have a different motion in rocky anchorages, not a lack of motion.

Life at a dock gets a little more tricky for catamarans. Most marinas were built long before the catamaran trend and feature traditional slip sizes meant for monohulls. Marinas have to put catamarans on t-heads or make other accommodations. Therefore, it can be harder and more expensive to find a catamaran-friendly dock. 

Once at a dock, the massive space of a catamaran can be harder to heat and cool efficiently. Catamarans usually need several air conditioners or heaters installed, whereas a monohull can get by with only one or two. That also means that cats might need more power (50 or 100 amp service instead of 30 amp) than some marinas can provide.

Monohulls will have fewer issues finding marinas that can accommodate them, and they pay standard rates. 

When sailing in protected waters, catamarans usually speed past their monohull friends. A catamaran provides a flat ride and sailors can move around their boats easily to make sail changes as needed. Walking on a catamaran’s deck is undemanding. 

Catamaran sailors also have many options to rest comfortably underway. Because catamarans don’t heel over, catamaran sailors can sleep in their usual cabins. They can move about the interior of the boat with ease. Cooking in the galley doesn’t usually look any different underway.

In similar conditions, a monohull will heel over. Some sailors love the feeling of being heeled over and feeling the wind in their hair. Some don’t. It can be more challenging to walk the decks and work sails on a monohull vs a catamaran. While in the cockpit, monohull sailors will want to sit on one side and may even need to brace themselves to stay comfortable. For long trips, there is no doubt that living while heeled over for days at a time is exhausting. 

Moving around the interior of a monohull boat at sea is also more challenging. Monohull sailors usually sleep in sea-berths with lee cloths instead of their usual quarters. It would be very uncomfortable to sleep in a v-berth underway, as the bow may be continuously pitching in seas. The lee-cloth in the sea-berth helps keep a resting sailor in their berth instead of falling onto the floor. 

Monohull boats have gimbaled stoves. Even while the boat is heeled over, the galley stove will remain level. However, cooking in a monohull while underway is still more challenging than cooking in a catamaran since the cook needs to constantly brace themselves against the heel and rolling motion. 

At the same time, none of this is to say that catamaran sailors have it easier at sea. In reality, catamarans may be more level, but they feel every wave in the ocean twice. The result is a choppy, bumpy ride with no rhythm. It can be just as tiring as being heeled over in a monohull.  

Catamaran vs Monohull Sailing Compared

Here are just a few ways that catamarans differentiate themselves from monohulls as platforms for living aboard.

• Living space—quantity and quality
• Storage space and weight
• Budget—purchase and routine maintenance
• Maintenance
• Catamaran vs Monohull for Circumnavigation
• Docking and close-quarters maneuvering

Catamarans have significantly larger and often more attractive living spaces. On the other hand, the living space on a monohull is usually small and can be dark due to small windows.

A monohull’s cockpit tends to be small and focused on safety. Families are more likely to feel in each other’s way, and moving around while others are seated can be awkward. On a catamaran, the cockpit is likely to be large and social. Catamaran cockpits have large tables and lots of lounging space in the cockpit.

Catamarans have large trampolines forward, which provides another comfortable, social lounging space that monohulls lack. Many catamarans also feature additional lounge space via the large cockpit roof. 

The salon on a monohull is located in the main cabin. A monohull’s salon will be smaller than a similarly-sized catamaran. Often there is a small table, room for several people to sit, and a single sleeping berth. 

Catamarans feature a wide bridge deck that crosses both hulls. This large living area features great visibility, ventilation, and natural light. On some catamarans, the galley is located on the bridge deck (called “galley up”), and on others, the galley is located in one of the hulls (called “galley down”). 

Monohulls have sleeping quarters in the bow and stern of the boat. On smaller monohulls, the main sleeping area is usually a v-berth. Older, smaller monohulls usually have just one head. 

On a catamaran, the sleeping quarters are located in each hull. These cabins often feature regular-sized boat beds and large en-suite heads. Cabins on a catamaran usually offer more privacy than monohulls. 

Catamarans are popular with charter companies because large families or groups of friends can enjoy living on a boat together in style and comfort. Each will have a private cabin and a private head. In addition, if you want to find space to exercise, do yoga, or watersports, you’ll find these activities much easier and more comfortable on a catamaran. 

Catamarans have more space in general and certainly have more storage space. The additional deck space catamaran designs offer lends to easy storage for larger items, such as paddleboards and kayaks. Catamarans can often hoist and store larger dinghies than monohulls can. Large compartments make storage easy. 

However, many catamaran owners are very cautious about storing too much. Additional weight can slow down a catamaran’s performance speeds. With so much space to put things in, it’s remarkably easy to overload a cruising catamaran. Many owners complain about the performance of smaller cats, when in reality they are often just badly overloaded.

Monohulls have less space and less storage. Finding space for big items like water toys can be challenging. But monohullers worry less about weight and freely carry around their cast iron skillet collections—because weight doesn’t impact performance on a monohull nearly as much. 

This is a consideration when cruisers consider adding additional equipment. For example, a catamaran owner will have to consider the added weight of a generator and its detriment to sailing speed. In contrast, a monohull owner will have to consider finding space for the new generator. 

Some prefer the motion of a monohull while sailing. Monohulls heel over but are steady, and sailors usually get used to the heeling motion. On a catamaran, if conditions are good, the boat won’t heel and will provide a comfortable ride. 

When sailing upwind, some catamarans experience bridge deck slamming. Waves get caught between the two hulls and create a slamming motion and sound. It’s hard to predict the timing and strength of each slamming motion, so some catamaran sailors can find it tiresome. 

The amount of bridge deck slam varies from boat to boat. Catamarans with higher bridge decks will experience less slamming, while boats with bridge decks closer to the water experience more. 

Beyond that often-discussed issue, there is also the issue of the boat’s motion. It’s very difficult to imagine how different the motions are when compared to one another. The monohulls slice through the waves, usually with a predictable rhythm. A catamaran, built lightly to sail fast, feels more like it bounces over the tops of waves. The crew will feel each impact as each hull hits each wave. The result is a choppy, unpredictable motion—but it’s generally flat and level.

Monohulls have been around for ages. Therefore, sailors just starting out can find inexpensive, older monohulls. If you have a tight budget, you’ll probably start looking for a monohull.

Catamarans are newer to the market. Therefore, the initial purchase price of a catamaran is likely to be higher. Monohull buyers can often find a used, well-equipped, comfortable monohull for less than $100,000. Catamaran buyers usually spend upwards of $250,000 for a used cruising catamaran. 

Because monohulls have been produced for so long, there is much more supply. The catamaran’s more modern pedigree means that there are always fewer catamarans on the market than monohulls. As more and more customers are drawn to the attractive living space and stable sailing offered by catamarans, demand keeps going up, while supply remains low.

Besides the higher up-front costs, catamarans are more expensive to keep and maintain. A monohull usually just has one engine. A monohull might have one head (bathroom) and will generally have less equipment. Monohulls have less space and storage, after all. Catamarans have twin engines, multiple heads, more hatches—more everything. 

With more equipment, catamarans have higher maintenance costs. When a monohull owner services their engine, they have just one engine. A catamaran owner will need to service twin engines. Furthermore, each hull on a catamaran usually has separate and independent systems like bilge pumps, plumbing, fuel, water tanks, holding tanks…the list goes on. 

A monohull owner will paint one hull bottom and wax only one hull. A catamaran owner will do everything twice. Therefore, the effort and cost of maintenance are often doubled on a catamaran. 

Not only does it cost more money, it can also be harder to accomplish maintenance on a catamaran. You see, catamaran owners have fewer options to haul out. Most older boatyards have travel lifts that only accommodate boats up to 18 or 20 feet wide. Therefore, catamarans need to find a boatyard that has a large enough travel lift or a trailer to haul them. Because there is less supply and more demand for these larger travel lifts, the cost of hauling out a catamaran is often higher. 

While some monohulls have lifting or swing keels and can reduce their draft, most catamarans have a shallow draft. This allows them greater flexibility while choosing anchorages. Even if a catamaran and monohull boat choose the same anchorage, the catamaran can get closer to shore and get better wind protection. 

One final big difference between these two types of vessels is their ability to maneuver in tight spaces. Monohull sailboats are notoriously difficult to maneuver around docks and marinas. They often have poor visibility from the helm and difficult handling, especially in reverse. The single-engine design often requires a bow thruster, even on smaller boats. 

The contrast that catamarans offer is pretty stunning. Even though they appear massive and ungainly in comparison, their twin engines mounted far outboard enable them to spin in their own length. Catamarans can be maneuvered in pretty much any direction using only differential thrust from the engines–all without a bow thruster.

Safety Considerations — Are Cruising Catamarans Safe?

Since most people have only limited experience with these vessels, many people wonder are catamarans safe. Even though they have been making large cruising cats for decades now, most of us have only really played on Hobie cats at the beach. And if there’s one thing we know about Hobie cats, it’s that they’re a lot of fun until you flip it over!

Here’s a look at a few safety considerations and how catamarans stack up against monohulls. 

• Catamaran stability — capsize potential 
• Hull breaches and sinking risk
• Rigging failures
• Designing for speed
• Redundancy on board

So, can you capsize a cruising catamaran? The answer is yes, no matter what the fanboys and girls say. It is technically possible but highly unlikely. Cruising cats are massive, and in all likelihood, you’re more likely to break the rigging than flip the boat. But in rough seas and extreme conditions, it does happen even on modern catamarans.

If a monohull encounters strong winds and rough weather, it will heel and roll significantly—but it will keep righting itself. In dire conditions, the vessel could suffer a knockdown. But a monohull will always right itself after a roll—it has tens of thousands of pounds of heavy keel to ensure that it does. Of course, the rig and anything on deck will sustain serious damage in the process, but the boat will be upright in the end. 

In the same scenario, while unlikely, a catamaran can capsize. And the catamaran will then remain capsized, with no possibility of righting itself.  

One of the scariest risks at sea is that of a serious hull breach, one that a bilge pump couldn’t keep up with. For example, a boat could be holed by an errant floating object or suffer a stuffing box or through-hull failure.

If a monohull sailboat is holed, it could sink straight to the bottom of the ocean. The crew would be left with only a liferaft and whatever they were able to recover before the sinking.

But a catamaran is filled with foam and is (more or less) unsinkable. If a catamaran experienced a hull breach or capsizes, it would take on water and may become less habitable. However, it will still float. In many cases, not much of the boat is left above the water—but it’s still at the top of the water.

Boaters may be able to perform emergency repairs and get the boat to port themselves. Or, they may have to stay with their vessel until help arrives. In either scenario, the crew maintains access to supplies and can stay with a much larger vessel, increasing the likelihood of being found and rescued. 

Some catamaran sailors are so certain of their vessels floating in all scenarios that they don’t even carry a liferaft aboard. This is fool-hearty, to say the least, given the crazy and unpredictable things that can happen to any boat on the ocean. But one scenario is equally scary for the monohull or the catamaran sailor and should convince everyone that any offshore vessel should have a liferaft—the possibility of an uncontrollable fire.

Rigging Safety

When wind speed increases, a monohull will heel over. This heeling motion sheds the excess power of the wind. Monohull boaters should pay attention to the weather and reduce sail to ensure they aren’t overpowering the boat. This is why knowing how to reef a sail is so important for all sailors.

However, on a catamaran, the sails and rigging take the increased load when wind speed increases. Catamarans don’t heel, and therefore, don’t shed excess power. If the weather becomes gusty and a catamaran has too much sail up, all that extra power is transferred to the sails and rigging.

This can cause a dangerous situation. For example, there have been reports of catamarans being de-masted in sudden gusts of wind. In a worst-case scenario, a catamaran could capsize if they are over-canvassed when experiencing extreme wind conditions.

Most monohulls have strong standing rigging. The forestay is connected to a solid structure, the hull. This means that the forestay has a strong, stable platform and gives a monohull better upwind performance. Monohulls also usually have backstays, which provide rigging redundancy.

On a catamaran, the forestay is attached to a crossbeam. Because the platform is not as rigid as a monohull’s hull, the forestay is not as strong. In addition, catamarans usually don’t have backstays, and therefore have less rigging redundancy. 

The configuration of the rigging is another rigging consideration. On a monohull, the spreaders and shrouds are perpendicular to the mast. Most catamarans come with fractional rigs that don’t have backstays, and their shrouds are set far back. Because of this configuration, catamaran sailors can’t let their mainsails out all the way on a downwind run because the shrouds are in the way. This leads to less efficient sail shapes when sailing downwind.

However, catamaran sailors can rig their sails to sail wing-on-wing. While monohull sailors can also use this configuration with the help of a whisker pole, catamaran sailors have a nice, wide, stable platform to fly large downwind sails. 

There’s no doubt about it–catamarans sail faster. Most articles and comparisons state that catamarans are about 20% faster than a similarly sized monohull. Catamarans have a lower wetted surface area and less drag than monohulls. They’re especially nice to sail in light winds, conditions that heavy cruising monohulls tend to not do well in.

While most cruising cats can’t sail upwind as high as monohulls can, they still win the race. However, if a catamaran has daggerboards and a good sail inventory, it can point as well as a monohull. 

Many boat owners believe that speed equals safety, as you might be able to outrun an impending storm. That’s a debatable strategy since weather systems often move faster than any cruising boat can move. It has a lot more to do with planning and the decisions made by the skipper, in the end. 

Furthermore, more speed means a rougher ride. A heavy, full-keeled monohull might not move very fast, but the sea-kindly and forgiving ride means a more comfortable and better-rested crew. This only goes to illustrate that the “more speed” argument is far more of a personal preference than many sailors admit—especially when it comes to long-distance cruising.

A faster boat provides a skipper with more options, but it does not ultimately equal inherent safety. That will always come down to the skipper and the crew, and the choices they make. A slow boat in the hands of an experienced and careful crew will always be safer than a fast racer under the command of an inexperienced and green crew. In other words, there is no replacement for seamanship and careful planning.

Catamarans have two of everything. While this does equal double the cost and maintenance, it also provides redundancy. If a monohull’s single engine dies and there is no wind, they may have to call for a tow or wait for wind. If a catamaran’s left engine dies, sailors can just continue on the right engine. 

Twenty years ago, the majority of boats completing circumnavigations were classic bluewater monohulls. Monohulls are considered safe and capable circumnavigators.

But today, catamarans are establishing themselves as the more desirable choice for many circumnavigators. Catamarans are fast, stable, and capable of crossing oceans. In addition, catamarans can carry significant supplies and offer redundancies. Plus, the extra space that catamarans provide also means that the crew will enjoy watersports like diving, paddle boarding, and surfing. 

Since nearly all traditional routes are downwind “milk runs,” catamarans naturally excel along the way. If you take a look at the competing boats for the World ARC rally for the last few years, a definite trend is growing. More catamarans compete every year. Common entrants include Lagoon 450s and Antares 44s.

One of the most significant decision points when thinking about catamarans versus monohulls is your budget. If your budget is under $100,000, a monohull will be your best bet. If your budget is between $100,000 and $250,000, you can consider a smaller, older catamaran. Catamarans such as PDQs, Prouts, and Geminis will be in your budget. If you have a budget of over $250,000 and can afford higher dockage and maintenance costs, you can consider a catamaran.

Next, consider your comfort level. To try it out, you might want to charter both a monohull and a catamaran. Check out a sailing vacation in the BVI or with a company like Cruise Abaco. Taking classes at our local sailing school might also be helpful. https://cruiseabaco.com

Many folks are attracted to the larger, more comfortable spaces of a catamaran. However, some people feel more seasick on a catamaran and can’t get used to the motion.  So a lot of your decision will come down to personal preference. 

If you can’t imagine squeezing into a darker, smaller cabin in a monohull, then a catamaran might be calling your name. On the other hand, if you are a traditionalist who loves heeling and boats with a lot of teak, a monohull might be your dream boat. It’s just impossible to know how a boat will make you feel until you’ve experienced both.

Boaters often discuss the compromises involved in boat choices. Whether you choose a monohull or a catamaran, there will be some compromises involved. However, no matter which boat you choose, you can enjoy smooth sailing, beautiful anchorages, and some adventure along the way.

Which is better monohull or catamaran?

Both monohulls and catamarans are popular choices for cruising sailors. Which one is better depends entirely on your personal preferences and which boat is more comfortable and appealing to you. If you are on a tight budget, a monohull is your best choice. On the other hand, if you love large open living spaces, a catamaran will be the better option.

Which is safer catamaran or monohull?

When wondering are catamarans safe, always remember that the primary determinant of the safety of a vessel is its captain, not the vessel itself. Both monohull sailboats and cruising cats have important limitations that their skippers must know and abide by. 

Some consider catamarans safer because they are virtually unsinkable. If it has a hull breach or capsizes, it will still float. 

Others see the sea-kindly monohull to be the safer bet, as they are better designed to protect their crews from the elements in severe weather. They also cannot capsize, as their ballast provides a righting moment in all conditions. But on the other hand, if a monohull experiences a hull breach, it can sink.

Can catamarans handle rough seas?

Modern cruising catamarans are built strong enough to cross oceans and survive in all kinds of conditions. It might be an uncomfortable ride, but not an unsafe ride. In the end, it is the skipper of the boat who ensures its safety at sea. Good seamanship makes a far bigger difference in how a boat handles rough seas than the design of the boat does. 

In extreme conditions, such as hurricanes or sudden gusty winds, catamarans can capsize. Once a catamaran has capsized, it won’t right itself. However, it will still float, although upside down. Heavy seas are more likely to cause maintenance and chafing issues on both catamarans and monohulls.
