• Brand-Specific Forums

Hi all, I'm seariously thinking of buying an Irwinn 33. I cannot find much info on it. i thoought i would ask here for some insights at least into the brand as I don't know much about them. I'm upgrading from an 1977 O'day 22 and it has been a great boat so, the age doesn't scare me. i've looked at the boat and all seems solid. i spoke to a surveyor who said it is as good as any boat that vintage. The phrf score is pretty low so i'm thinking it isn't a slow boat. Anyway would love some input before i make an offer. thanks in advance Danny

Used Sailboats from the 1970s: Practical Sailor Puts Plastic Classics Under the Microscope

Pearson 30, tartan 30, and catalina 30 stand out in colorful field of groovy fiberglass boats..

The fiberglass revolution in boats really hit its stride in the 1970s. Builders experimented, learned, and improved construction processes during the 1960s, so by the early 1970s, there were a lot of big- time builders pumping out a lot of good boats. In the East was Pearson Yachts; in the Midwest was Tartan Marine; in the South, Hunter Marine and Irwin; in Canada, C&C Yachts flourished; and out West were Jensen Marine (Cal), Ericson, and Columbia Yachts, to name just a few of them.

Narrowing The Field

In selecting a handful of 30-footers for review, we figured why review a boat no one can find? So we browsed online listings for plentiful boats. We also consulted our own files for old brochures, lines drawings, and owner comments, as well as past reviews of each model.

While there were at least several dozen 30-footers built in the U.S. during the hippy-dippy days of Woodstock, The Smothers Brothers, and Watergate, the most enduring are those built by the major builders—all-around family boats sometimes called racer/cruisers or cruiser/racers. Whatever you call them, they are fun to sail and have sufficient accommodations for a family to live aboard for a week’s vacation.

The facing table shows the nine models we settled on for preliminary discussion: Tartan 30, Pearson 30, Catalina 30, Hunter 30, Irwin Competition 30, Newport 30, Cal 2-30, O’Day 30, and C&C 30. For various reasons, a number of interesting 30-foot designs are omitted—the S2 (1977), Sabre 30 (1979), and Dufour Arpege (1968) come to mind—primarily because they are on the cusp of a different time period where they seem a better fit.

Before we move onto the chosen three, here are brief notes on six models dropped in the final cut.

More than 800 C&C 30s were built between 1973 and 1984, making it one of North America’s most successful 30-footers of all time. Though C&C was a pioneer in the use of balsa core in sandwich hull construction, the early C&C 30s have solid-glass hulls. Like other C&Cs of this period, the keel and rudder are swept aft.

C. William Lapworth was the designer for nearly all of Jensen Marine’s (Costa Mesa, Calif.) many models. The 2-30 was in production from 1967-1973, followed by the 3-30, which lasted until 1976. Cals have stout solid fiberglass hulls, but fairly plain interiors.

The Hunter 30 was an early model from Hunter Marine, a spin-off of the Luhrs’ family’s powerboat company, Silverton. The boat was in production from 1974-1983, with more than 1,000 built. It came with a deep keel or keel/centerboard. The rudder was skeg-hung. The designer was John Cherubini, who worked for Hunter at the time. Marketed for value, workmanship was below average.

Irwin Competition 30

Based in Florida, Irwin Yachts built three different 30-footers in the 1970s: the Competition 30 (1972), Citation 30 (1978), and the plain ol’ 30 (1975). All designed by Ted Irwin, one-time kingpin of southeastern sailboats who fell from grace with a thud. Shoddy workmanship resulted in lawsuits he couldn’t overcome. Many of his designs, however, were quite good. The Competition 30 was configured to rate as a 3/4-tonner under the International Offshore Rule (IOR).

Newport 30 (PHASE ii)

Capital Yachts (Harbor City, Calif.) introduced the Gary-Mull-designed Newport 30 PHII in 1971. Like Hunter and Irwin, Capital Yachts’ boats were built to a price. Like the Irwin Competition 30, the Newport was designed to compete as a 3/4-tonner under the IOR. It’s noticeably lighter than many of these boats, and has a shorter waterline.

O’Day 30

More than 350 O’Day 30s were built between 1977 and 1984. Designed by C. Raymond Hunt Associates and built by Bangor Punta Marine, the boat came with a full keel or keel/centerboard (3’6″-7’2″). In 1984, the stern was stretched to make the O’Day 31. By some reports, the Ranger 30 and O’Day 30 share the same hull. (Bangor Punta bought the Ranger and Cal lines from Jensen Marine.)

Bottom Line

At this age, maintenance history is key. Any upgraded and well-preserved specimen from the above group may serve well as a family coastal cruiser, but we’d focus on the three finalists on the following pages: the Pearson 30, the Tartan 30, and the Catalina 30. All are fin keel, masthead sloops, but each has unique features that sets it apart and will appeal to certain buyers.

The Pearson 30 is the smallest of the three, but a good sailing boat that still competes in club races. It’s the lowest priced of the three. If you’re counting dollars, grab the best one you can find at your price.

The Tartan 30 has a stronger following than the Pearson, partly because of its S&S pedigree. It, too, sails very well. Engine placement poses some complications, but you can get used to it.

The Catalina 30 is the logical choice for the family battlewagon. It’s heavier, roomier, newer … and more expensive. With a displacement/length ratio of 291 and a sail area/displacement ratio of 15.1, however, don’t expect performance matching the Tartan 30 and Pearson 30.

Budget-friendly Pearson 30 reflects Bill Shaw’s growing influence.

The Pearson 30 was introduced in late 1971, and when the last boat went out the door in 1980, 1,185 units had been built. Most were sold in the early and mid 1970s. All were built in Portsmouth, R.I. The P30 was succeeded by the Pearson 303.

Bill Shaw joined Pearson Yachts in 1965, after Grumman bought the company from Everett and Clint Pearson, and during the following few years, he began to exert his influence on the design of the yachts. Fin keels and spade rudders replaced full keels with attached rudders, underbodies became shallower, and displacement less. In short, Shaw modernized the Pearson fleet, and the Pearson 30 is a good example of contemporary design at that time, in particular the swept-back keel and scimitar-shaped rudder. George Cuthbertson was drawing similar appendages at C&C, noting that test-tank data indicated super speed, but on the water, they proved not as efficient upwind as vertical keels and rudders with higher aspect ratios. Extra care must be taken in blocking the boat if not in a cradle.

Our July 15, 1984 review of the Pearson 30 added these comments: “The boat’s underwater shape is somewhat unusual. The hull is basically dinghy-shaped. The sections aft of the keel are deeply veed, however, so that deadrise in the forward and after sections of the boat is similar. Coupled with a fairly narrow beam by today’s standards, this provides a hull form that is easily balanced when the boat is heeled—an important consideration in this relatively tender 30-footer.”

Construction

The hull is a solid laminate with alternating plies of 1½-ounce mat and 18-ounce woven roving. The skin coat under the gelcoat is two layers of mat to prevent the pattern of woven roving from showing (print-through). The external flange of the hull-deck joint is secured with self-tapping screws and then fiberglassed. The deck is balsa-cored for stiffness.

Interestingly, the Pearson 30’s lead ballast is encapsulated in the fiberglass keel molding, which means there are no keel bolts to worry about. This is somewhat unusual for a fin-keel boat.

About the only problem particular to this boat is the rudderstock. Early boats had aluminum rudderstocks, some of which broke, prompting the company to replace the approximately 200 others with stainless steel. Even the stainless steel stocks were not without problems, turning as they do in Delrin bushings, which wear and cause slop in the steering system. They are owner replaceable, however, by removing the tiller fitting and dropping the rudder.

Molded fiberglass floor pans and headliners are bonded to the hull and deck. Through-hull valves may be gate valves (like garden faucets) or positive action seacocks; chainplates are properly through-bolted to structural bulkheads.

Pearson Yachts’ construction methods were above average.

Performance

Though not designed specifically as a racer, the Pearson 30 enjoyed many successes in IOR and Midget Offshore Racing Club (MORC) classes. In fact, it won the ¾-Ton North American championship in 1972. And it was a very popular club racer. It balances well and is quick through tacks. On the downside, it is tender. Our 1980 reviewer wrote, “In 15 knots apparent wind, we find that the boat is almost overpowered with the full main and 150 percent genoa. Gusts of 12-14 knots bury the rail, slowing the boat. The P30 does not, however, carry any substantial weather helm even when overpowered. Any tendency to round up or spin out can usually be controlled by a strong hand on the tiller and easing the mainsail.”

For family daysailing and cruising, smaller headsails are recommended.

Still actively raced in local fleets, a typical the Pearson 30 has a PHRF number of 174 seconds per mile.

Accommodations

The interior layout of the Pearson 30 is straightforward, with a V-berth forward, small enclosed head, settees in the main cabin, a quarter berth aft to port, and a compact galley in the starboard quarter area. The port settee converts to a double berth, so the plan totals six berths, which are more people than you’d want to spend much time with on a 30-footer.

The four portlights in the head and forward cabin are opening, which combined with the forward hatch provide decent ventilation. Unfortunately, the forward hatch isn’t big enough for emergency exit. There is no anchor well in the foredeck, a feature that became more common later in the ’70s.

There’s adequate stowage under, behind, and above the settees. The 1984 reviewer wrote: “Although the lockers are sealed to the bilge at the bottom, owners report that, with their boat heeled, bilge water finds its way into the lockers by running up the inside of the hull behind locker partitions, then down into storage spaces. Most dinghy-hulled boats lack real bilge space or a sump, and as little as a gallon of water in a boat of this type can be annoying.”

Other shortcomings are limited engine access (though not any worse than most boats of this size), and a galley sink and spigot that partially block the companionway. On the upside, the interior is light and airy. Headroom is 5’ 11″ in the main cabin.

As with any boat of this age, one should ask the surveyor to look closely for delamination of the core and deck skins, separation of the hull-deck joint, water in the rudder, corroded electrical wiring, corroded through-hulls, and hoses that need replacement.

On early Pearsons the cockpit scuppers were connected to the bottom of the hull by fiberglass tubes, rather than hoses and seacocks/through-hulls. Though probably safe and secure, this drain system does not satisfy American Boat & Yacht Council standards.

As noted earlier, there are just a few areas in which the Pearson 30 falls short of quality building standards, principally the rudder stock design in which bushings wear faster than usual.

Pearson Yachts once ran one of the best customer service departments in the business; alas, it’s been out of business for more than 20 years, and several of the more helpful owner association web sites seem to have disappeared.

The Pearson 30 is a fun boat to sail—quick and responsive. It has the lowest displacement/length ratio (238) and highest sail area/displacement ratio (17.3) of the three. If you like performance, the fact that it’s a little tender shouldn’t bother you much. Reef or just enjoy the ride. It’s not a big 30-footer, but nicely proportioned and of better- than-average construction. There are quite a few on the used boat market in the low and mid-teens, enabling bargain hunters to get into a full-size boat for not much money. Asking prices we saw online, for all years, average around $14,000, with lows around $8,000 and highs around $25,000.

Tartan 30 brings fine S&S cachet within reach of ordinary Joes.

Built by Tartan Marine in Grand River, Ohio, and at a plant in Hamlet, N.C., between 1971 and 1980, the Tartan 30 was one of the first designs introduced by Charlie Britton after buying out partner Ray McLeod. The company could complete a boat in less than 4 days. It filled in the gap between the Tartan 27 and Tartan 34. Production totaled 630 units.

The Tartan 30 (like the 27 and 34) was designed by Sparkman & Stephens, probably the world’s most prestigious yacht design firm at that time. The lines are clean and crisp. Like the Pearson 30, its LOA is 29’11,” so it could qualify for competition under the MORC, a rating rule under which it proved quite successful. The bow is raked, and the reverse transom gave it a very modern look for the early 1970s. It has a fin keel and skeg-mounted rudder; a Competition model offered a taller mast (by 3 feet), deeper keel (5’6″ vs. 4’11″ for the standard model), and 500 pounds more ballast. It’s beamier than the Pearson 30, and of about the same displacement, but with a slightly shorter waterline. The rig is fairly high-aspect ratio with large headsails.

A highly unusual feature is the location of the Atomic 4 auxiliary amidships, under the dinette table. This places the considerable weight of an engine exactly where you want it most, near the center of gravity, to minimize hobbyhorsing, which slows a boat and is uncomfortable. Access is better than the usual location aft behind the companionway. And that space is opened up in the T30. The disadvantage is it takes up space in the saloon, particularly seatspace and legroom at the table.

The lamination schedule is typical of this period: hand-laid mat and woven roving. Liners make for an easy-to-clean interior, but make customizing difficult; they also tend to sweat more than wood interiors, and are noisier.

Ballast is external lead hung on 1-inch stainless steel keel bolts. The rudder is partially supported by a bronze shoe secured to the skeg.

Interior and exterior wood is teak. The sole is covered with cork, a quality home flooring material of the 1950s and ’60s.

Of the rig, our Jan. 15, 1987 review noted: “The rig, like most of those specified by Sparkman & Stephens, was designed to be practically indestructible. Given its inherent strength, look primarily for the effects of corrosion at the spreaders and the butt. Many 30s have been fitted with babystays in lieu of forward lower shrouds. For typical cruising we think the babystay is a pain and probably unnecessary, so we’d make it detachable.” Some owners added babystays as a cure for mast pumping. The standard rig has just single lower shrouds.

Early T30s had bronze pipe (no flanges) for through-hulls as well as gate valves instead of seacocks. Diligent owners will have replaced both by now, but it’s worth checking.

Blistering of all boats was not as common as later in the ’70s and into the ’80s, but there were isolated cases for which one should be on guard.

Tartan’s quality of construction, in the early ’70s, was at least as good as Pearson’s, in some respects better, in others not. It was certainly better built than the Catalina.

The Tartan 30 is a wholesome design with few bad habits. Our 1987 review said, “The Tartan 30 sails well. In a breeze to windward—perhaps the best test of any boat—she is at her best: comfortable, stable, reasonably handy, and modestly dry. Off the wind, she is more steerable than a host of successors with free-standing spade rudders and dagger-thin keels. Only on a broad reach with biggish following seas can her weather helm be tough to handle. Under such conditions, good sail control hardware—vang, traveler, reefing, adjustable backstay, etc.—is important.”

The skeg helps provide good directional stability or tracking, and the narrow sheeting angles (due to inboard genoa tracks) contribute to narrow tacking angles. The largest T30 PHRF fleet in the U.S., on Lake Erie (20 boats), races with a handicap of 168, though most of the other fleets, including the 18-boat fleet on the Chesapeake Bay, rate higher, around 177. So it and the Pearson 30 are very similar in boat speed, though the Pearson has the edge in light air, where the Tartan’s shorter waterline is a disadvantage.

Two interior plans were offered, one with an aft galley, the other with a midship galley, the latter with two quarterberths, the former with a single quarterberth to port and a settee amidships to starboard, where the galley is in the midship model. With either, there are simply too many berths. The aft galley seems preferable mainly because of the two opposing settees in the saloon.

One reason why five berths in a 30-footer is at least one too many is that berth length is diminished; this is particularly evident in the V-berth. Another reason is that quarterberths subtract from available stowage space; instead of stowing sails in cockpit seat lockers, on this boat they end up in a quarterberth.

The midship galley is, of course, more spacious than the aft galley, but neither has a stove/oven combo. Owners note that when the boat is heeled, the sink can fill and slosh water onto the sole.

The cockpit is of average size and would be more comfortable if the wood coamings weren’t so low.

Beyond the usual issues afflicting old boats, like bedding failing on deck hardware, the Tartan 30 has few peculiarities of construction. A number of owners have installed tie rods between the lower portion of the mast in the cabin, and the underside of the deck, to prevent deflection when the rig is heavily tensioned. Check tabbing of the main bulkhead. Also check the starboard chainplate and its attachment to the bulkhead, which reportedly isn’t as stiff as the port side bulkhead; water migration down a chainplate and into a wood bulkhead is a serious problem. Other issues noted online include inadequate insulation of the ice box, and an engine exhaust system prone to back-siphoning.

Tartans enjoy very active owners groups, especially in the Chesapeake Bay area. T30 owners’ websites have much useful information on troubleshooting and upgrading.

The Tartan 30 is probably the classiest boat of the three finalists. Part of the reason is that Sparkman & Stephens is one of the world’s great yacht design firms, and the work they did for Tartan was very good, with handsome, classic lines. And Tartan construction was above average. Online asking prices start at just under $10,000 and run up to around $23,000, with an average of about $17,000.

The family-friendly Catalina 30 comes with the largest fan club.

More than 6,500 Catalina 30s have been built since the boat was introduced in 1974, which must be some kind of record. Its design was continually upgraded over the years, but the first model, the Mark I, was in production through the same period as the Pearson 30 and Tartan 30. The Mark II came along in 1986. Owner Frank Butler has built more than 70,000 boats since he founded the company in 1970, so he must be doing something right. In 2001, the Catalina 30 was inducted into the American Sailboat Hall of Fame.

Butler drew most of the early designs himself, though he has no formal training in naval architecture or yacht design. He was a machinist by trade, and smart. His first design was the Coronado 25, which he’d asked Sparkman & Stephens to design, but they told him it would take two years and they’d first have to check his finances. So he designed the boat himself, with a fiberglass pan interior, which he believes was an industry first (Henri Amel was doing something similar in France.)

The Catalina is three years newer than the Pearson 30 and Tartan 30, and was not intended as a racer, which explains its wider beam and heavier displacement. Like most Catalinas, the 30 is a family boat, best suited to coastal cruising.

Here’s what we said about the design in our Nov. 15, 1980 review: “The boat has a swept-back, fairly high-aspect-ratio keel of the type made popular by IOR racing boats in the early 1970s. The high aspect ratio spade rudder is faired into the underbody with a small skeg. The boat is conventionally modern in appearance. She is moderately high-sided, with a fairly straight sheer and short ends. The cabin trunk tapers slightly in profile, and is slightly sheered to complement the sheer of the hull. When coupled with the tapered cabin windows—a Catalina trademark—this yields a reasonably attractive appearance compared to many modern boats.”

Of course, what was modern in 1980 and what is modern today are two different things. For one, waterline lengths have increased in relation to length overall, which means shorter overhangs, which means bows that are more plumb.

The hull of the Catalina 30 is solid fiberglass; there is no balsa, no foam, which makes for a heavier boat, but also one that isn’t susceptible to potential delamination. The hull-deck joint is a shoebox, in which the wider deck, with downward-facing flanges, fits over the hull. It is then bonded and fastened with self-tapping screws. A wood sheerstrake glassed to the hull adds strength. The joint is then covered with a vinyl rubrail secured in an aluminum extrusion.

Shoal and deep keels were offered, both external lead through-bolted to the hull.

The masthead rig has upper and double-lower shrouds and is deck- stepped. A wood compression post transfers rigging loads to the keel. A tall rig, for light-air regions, was an option. Check wood spreaders for rot. Early boats had fixed portlights, but these can be upgraded to opening.

Stanchions, double lifelines and double stern and bow pulpits were standard. Stanchions are though-bolted, but backed only by washers, not backing plates of fiberglass or aluminum, which do a better job of transferring loads and preventing cracking of the gelcoat, and possibly the deck laminate, in way of the stanchion bases.

Like Tartan, early models had through-hulls made up of bronze pipe. Gate valves were standard and must be replaced with bronze positive-action seacocks.

The Catalina 30’s generous beam (for its day anyway) gives it good initial or form stability. And coupled with a conservative sail plan, the boat is stiff, much more so than the Pearson 30. The downside of such beamy hull forms is the tendency to develop weather helm when heeled; so it, like many other modern boats, is best when sailed relatively level.

The smallish sailplan also means that performance in light air is not particularly sparkling. Our 1980 review said, “To get good performance in light air the boat will either have to be ordered with the taller rig, or very large headsails must be carried. If headsails larger than a 150% genoa are carried with the normal rig, turning blocks will have to be added aft in order to get a proper lead to the headsail sheet winches.”

The biggest Catalina 30 PHRF fleets, both in California, rate 180 and 192 respectively; the Pearson 30 is 174 and the Tartan 30 177.

A gasoline Atomic 4 engine was standard; a small, underpowered diesel was optional. Look for a boat that’s been repowered with a newer engine like the Yanmar 3GM30F.

Interior “furniture,” such as berths and galley, are formed by an interior fiberglass pan or module dropped into the hull prior to the deck going on. A fiberglass headliner covers the underside of the deck. These make for an easily cleaned interior, and one that looka nicely finished (albeit like a refrigerator). Such liners do, however, restrict access to parts of the hull and deck, make customizing difficult, and are not as good thermal and acoustic insulators as wood. The bulkheads are teak-faced plywood.

Again, owing to its beam, the Catalina 30’s interior is more spacious than the Tartan 30’s or Pearson 30’s. The V-berth is comfortable, followed aft by the head and hanging lockers; a shower was optional. The engine is located very near the center of the boat, under the short leg of the L-shaped portside settee. Access is very good. There’s a U-shaped galley with alcohol stove/oven to port, and a quarterberth and chart table to starboard. But if you thought the Tartan 30 has too many berths, check this: The Catalina 30 supposedly sleeps seven! Two in the V-berth, two in the convertible portside dinette, one on the starboard settee, and two squished into the “double” quarter-berth.

The interior is spacious and wellplanned, but finish quality is only average.

The Catalina 30 is a pretty straightforward boat in terms of both design and construction. No big surprises.

Several potential issues mentioned recently on owner forums: corroded wiring harness between engine and control panel, poor rudder design (corrected with new design in December 1978), wear of rudderstock tube, chainplate attachment to bulkheads, gate valves on pipe through-hulls, and hollows in the lead keel.

A positive with any Catalina is that the company is still in business and able to offer customer support.

Catalina Yachts has been one of the country’s most successful builders because it offers a lot of boat for the money. If construction quality is only average, one must ask, “Do I need more?” Generally, what’s lacking is not structural integrity, but details, like more drawers with dovetail joints and hardwood sides. There’s lots of room in the Catalina 30, and there are hundreds on the used boat market, so you can find a deal. Because the Catalina is a somewhat newer boat than the Pearson 30 and Tartan 30, its prices run higher. Though fixer-uppers can be found, most run between $16,000 and $29,000, with an average of about $22,000.

An examination of 30-footers from the 1970s seems like a good place to begin our comparison of used boats, and the reasons are several: First, though boats 30-plus years old admittedly are getting a little long in the tooth, many are still around, and those well kept may represent great buys on the used-boat market—between $10,000 and $20,000. Second, the 30-foot size is where full cruising accommodations begin, with stand-up headroom, enclosed head, berths for four or five, inboard auxiliary engine, and a decent galley with ice box, sink, and stove-oven possible. Sure, you can find these features in some 27- and 28-footers, but the squeeze is telling.

Can anyone give me any info on how much one of these boats is worth? Fair condition.. needs new sheets and some work done... rough ideas are welcome  

Well NADA suggest list of $24k, with a average retail of $10k and low retail of $9k. https://www.nadaguides.com/Boats/1974/Irwin-Yacht/IRWIN-33-SL/10093864/values New sheets, maybe $50.00. Engine, standing rigging, sails, deck saturation, wiring, rudder condition, drive train, and on and on. Blisters? Value is hard to say even from pictures. My suggestion, look at a ton of boats before buying one. Boats are like wives, hard to get, expensive to keep and you are going to lose a lot of money when you rid of them.  

I have a feeling he meant sails, as sheets would be an inconsequential expense when buying a boat, as you pointed out.  

I have been researching boat prices for nearly 5 years. I have read ads on various web sites and at various brokers pages. I have called after the sale to find out what boats actually sold for, compared to the original asking price. One thing I have learned is that there is really no way to judge the sale value of used boats like there is with cars. Prices seem to vary drastically depending on things like region of the country, condition of several different systems on the boat, and even whether they were used on inland lakes or saltwater. Prices are influenced by the reputation and pedigree of the boat model, designer and builder. Prices can be influenced by a large variety of available navigation and communication equipment, and refrigeration and autopilot add-ons. I've noticed that a boat that has a reputation as a good racer, but as being less comfortable as a cruiser, may go for less in the Bahamas than a comparable boat in the Great Lakes. Conversely, I've noticed that a boat that has a strong pedigree as a blue water cruiser may sit for some time unsold on the Great Lakes but a comprable model located in a coastal area in the South may sell rather quickly at a higher price. I watched the ad for one boat for a while that proudly advertised that it was equipped with a loran navigation system. Loran systems have not been supported with shore stations for about 15 years or more.  

Thank you all. I looked everywhere for the NADA so thanks for the link. I've been helping an 89 year old man take care of this boat and he wants to give it to me. I refused it for free and wanted to make him a reasonable offer. Its still solid, no blisters, it could use a new main sail within the next year though. I did mean new sheets, I just didn't know they were so inexpensive as everything else I've bought for it seems quite expensive.. He has told me more than once; "This is a rich man's hobby you know." HAHA. No salt water except two trips from Vermont to Maryland through the canal. As you can probably tell I've only really dabbled in sailing but I've taken a course and have been sailing with friends on many occasions. It needs some TLC for sure, but I'm really looking forward to calling it my own and working on restoring the things he has had to neglect due to his and his wife's health. I appreciate the quick responses.  

Irwin made several different 33 footers with a number of different configurations. In really good condition the boat is worth around $12,000-13,000, but that boat needs a new mainsail. A new mainsail will cost between approximately $1,100 and $2500 depending on the quality. If the mainsail is in rough shape then you probably need a new jib before long which is another $2,500 to $3,0000. Jib sheets for that boat would probably be 66 feet of 7/16" dacron double braid at roughly $1.35 per foot. The mainsheet would probably be around 70-80 feet of the same. And if the sheets are in bad shape, then you are probably pretty close to needing halyards. That makes the value of that boat closer to the $5,000 to $6,000 range and you will need to be prepared to spend double that ob maintenance if you own and sail that boat for more than a few years. Lastly I strongly suggest that you get the boat professionally surveyed so that you know whether there are any 'fatal flaws' such as keel bolts, which on the fixed keel model could easily be at the end of their 'use by date' especially since this is a fresh water boat and so would often more prone to crevice corrosion than a sail water boat. Jeff  

In Florida NADA values are worthless for older sailboats 35 feet and under in average shape - there are just too many for sale - some quote NADA values in their ads - and the boat never sells - they are only worth what someone else is willing to pay - which right now is not much - I would guess if your boat was in Florida and had a working diesel engine - it would sell between $5K to $8K - but is might sit for a while - Irwin is generally not a make that people go out of their way to look for -

2nd owner, entire life on freshwater in Lake Lewisville, TX 1975 Irwin 33 Lake Lewisville, Oak Point, TX Currently in a rented slip at the Dallas Corinthian Yacht Club - dcyc.org

For 5 yrs, this has been a project boat. All interior wood trim was removed to be stained and varnished (80%) complete - looks beautiful. Atomic 4 gasoline inboard engine head CRACKED. Previous weld failed, likely not winterized properly. Crack is on the water side, no oil in water. Transmission looks good with planetary reverse. New bimini and UV trim on genoa Sails are old, but fair condition - will move the boat but won’t win any races! Floats high on her lines, I walked all over the deck and does not seem to have soft spots, dry boat! No lie, boat needs a lot of work to be in any decent WAF (wife acceptance factor) and is the reason I need to part with it! Slip paid up through July 2022 Clear TX title in hand!

Offering a $1,000 credit (total) to Eagle Point marina for haulout AND http://www.usboathaulers.com to transport this yacht to your marina of choice. So, as soon as it it out of my slip and off the lake, it’s a free boat!

Sailboat data

Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

• SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
• D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

• D: Displacement of the boat in pounds.
• LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

• D: Displacement of the boat in pounds
• LOA: Length overall in feet
• Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

Shoal draft: 3.92’
