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)

Similar to the US-25. Later it became the TRITON 25 (Pearson Yachts). Thanks to Craig Montague for providing additional information on this yacht. Shoal draft version: 3.5’.

Modifying rudder - us yacht 25

• Add to quote

I have a US Yacht 25 with the shallow keel. The rudder on this boat extends about 8 inches below the keel and is therefore the first thing to hit bottom. In any case the rudder now needs repair and I'm wondering what problems I might cause by reducing it's length. The rudder is about 42 inches deep.  

Are you going to reduce the area of the rudder? If so it will make for a worse handling boat.  

I could compensate for the reduction in height by increasing the width. It's now about 42 x 14 inches. If I chop 6 inches off the bottom, I'd have to increase the width by 2.33 inches.  

Hi there, I'm too new to be allowed to send emails or private messages via Sailnet so I hope you don't mind me getting off topic here. I also have a US Yacht 25 (swing keel). You do not find much on the internet, or Sailnet, about these boats, probably due to their short production run and multiple company production lines, i.e Bayliner, US Yacht/ Pearson. I was curious to know about your experiences with the boat. Are you satisfied with it's performance? What year is yours? How do you feel about it's build quality? Personally this is my first boat which I received in July of 2011 so I do not have a lot to compare it to. None the less I find that it points reasonably well and accelerates to hull speed pretty quickly.  

I've had the boat for about 10 years. I'll have to look at the registration to get you the build year. It was a bit run down when I got it with lots of topside leaks mainly around the windows. The balsa core in the topside compounds the leak problem since you have no idea where the water is coming from. I dug out the balsa in the window openings and replaced it with epoxy and reset the windows and ports. I've also reset most if not all of the deck hardware and I now have no topside leaks. I've replaced the teak main hatch rails and the grab rails. I sail the boat on Lake Mendota in Madison Wisconsin about 9000 acres; smaller than the lakes in Kentucky I imagine. The boat is adequate for my purpose which is mainly day sails with an occasional overnight. It's quite stable with the heavy keel; I usually put in a reef as the wind gets over 15 mph as we often experience quite gusty conditions. I think the boat is over powered at winds above 15 mph without a reef. As you know the cockpit is a bit cramped but ok for 4 people. I've noticed people complain about the head door. I fixed that problem by replacing the door with two doors. One at the rear the width of the aisle that can be left half open closing off the aisle to expand the head when in use. The other smaller door is on the forward side. I also run the mast wiring down through the mast step and connect the wires to a terminal block in the head eliminating the on deck connector and it's attendant problems. The wire passes through a rubber stopper that gets pinched as you raise the mast. Let me know what else I can tell you. My email is mike.z.dorl AT gmail.com  

mike, I have a US 25 that I am parting out. The rudder is in good shape. If it helps, it's yours for the cost of shipping. It's one less part for me to toss in the dumpster.  

@bljones: Thanks for the reply about the US Yacht rudder. I'm certainly interested. I might also be interested in some of the other parts; things like the engine mount and the jib turning block cars. Could you send me some pictures of the rudder to make sure we are talking about the same thing and so I can assess it's condition? This is going to take some effort on your part and I'd like to help with any expenses you have such as packaging. Maybe I can arrange for pickup at a place convenient to you. Drop me a email at [email protected] as that's a much more convenient way for me to correspond with you. Regards, Mike Dorl  

I'm not an expert but have modified several blades over the years with good results. Based upon this limited experience your plan seems feasible. As you proposed you could compensate for the reduction in height by increasing the width. If you chop 6 inches off the bottom and increase the width by 2.33 inches, you'll still have a reasonable aspect ratio if all 36" remain immersed. You'll probably want to move the leading edge forward .6" and extend the trailing edge aft 1.7" to keep the maximum depth of chord in the same location. Assuming your rudder currently has a foil shape and you wish to retain a fair foil shape, you should refer to NACA foil shapes. A quick Google search came up with is link Foil FAQ It appears quite useful. As I recall, epoxyworks has a good article on fairing a keel which would give you a good idea what you're getting into.  

My first boat was the 22' version of yours. When I got her, the rudder was missing, so I had a guy in Texas fabricate one. We had nothing but a couple of 'net pictures to go by, so the one he made was nothing near the factory's original. Matter of fact, I had him make it into a "kick-up" rudder, which might be another option for you to explore, and it seemed to work well. The 22', of course, had a transom hung rudder, which is different from yours, but the concept of the overall geometry is the same. Having said that, I don't think shortening yours will cause that much effect, at least not enough that it can't be compensated for. Now that I've gained some experience owning these things, I'd make my own, for whatever that's worth.  

mikeinmid, check your email.  

I as well own a US Yachts 25 (swing keel) and am interested in any parts and pieces that you may have left.... would also like to get in touch with other owners for some info/questions....  

suppose you could number the pieces and I'll just epoxy them back together!!!!! (absolutely kidding) sounds like you are using most of the bits for another project, but if there are any parts in surplus I could possibly be interested...... thanks

Joe Lewis’ $250 million superyacht, ranked among the world’s 25-most valuable, sets sail after he pays US fine

Joe Lewis’ superyacht is on the move again after spending most of the past year holed up in a Mediterranean port while the British billionaire faced insider-trading charges in the US.

His 322-foot (98-meter) Aviva — which he put up as collateral for bail —  has traveled more than 400 nautical miles from Malta to cities along Albania’s coast as well as the Greek island of Zakynthos since  he was sentenced  April 4 to three years probation, according to data compiled by Bloomberg.

After departing Zakynthos earlier this week, the Tavistock Group founder’s yacht was near Kalamata in southern Greece on Thursday morning local time, the data show. It’s the most the roughly $250 million vessel has traveled in about seven months, though it’s unclear if Lewis is on board.

Lewis, 87, pledged his yacht along with his private jet to secure his release following his arrest in July. A few months later, Aviva docked until April 5 in the Maltese capital of Valletta, where it can cost as much as €750 ($800) a night to moor vessels that exceed 75 meters.

Lewis, who was scheduled to have eye surgery in London recently, was prohibited from setting foot on the yacht that has long served as part-residence, part-office while awaiting trial. He was only allowed on board after paying a $5 million fine after sentencing, which he settled soon after the verdict in Manhattan.

A representative for Lewis, who has a net worth of about $7.3 billion according to the Bloomberg Billionaires Index, declined to comment.

Lewis, whose global empire includes five-star hotels, private lenders and enclaves for the wealthy, launched Aviva in 2017. It includes eight guest suites, a helipad, padel tennis court, spa and a cinema. It ranked among the world’s 25-most valuable superyachts shortly after its launch, alongside those owned by Middle Eastern royals.

The yacht has also displayed works from Lewis’ private art collection, which is valued at more than $1 billion and includes pieces by Picasso, Freud, Klimt and Degas.

Events that authorities say took place on the yacht were a key piece of evidence that prosecutors used against him. 

At dinner one night in September 2019, the billionaire received favorable news about Mirati Therapeutics Inc., an oncology company where he was a major investor, leading him to pass along the tip to a host of people, including the pilots of his private jet, according to US regulators.

Those pilots — Bryan “Marty” Waugh and Patrick O’Connor — were also charged with trading on inside information. O’Connor pleaded guilty to securities fraud and conspiracy and is due to be sentenced in May, while Waugh is fighting the charges.

The US Navy has an unmanned 5th generation carrier stealth jet. It could be a game changer

U S aerospace firm Boeing is still hoping that the new MQ-25 Stingray drone it’s building for the US Navy’s aircraft carriers could be armed for combat. Sure, there’s a profit motive. But Boeing isn’t wrong. Adding missiles to the long-ranging, Stealthy MQ-25 – the Navy’s first in service carrier-capable drone – is a really good idea.

Put simply, the MQ-25 is the only aircraft currently in development for the Navy’s carrier air wings that possesses the range to strike at Chinese forces without forcing the carrier itself to sail dangerously close to those same forces.

The Navy tapped Boeing to build the tanker drone back in 2018. Six years later, the first batch of drones is in production at the company’s new factory in Missouri. The Navy expects the $180-million drones to deploy for the first time in 2026.

As the Navy envisions it, the 51-foot MQ-25 is strictly an air-to-air tanker – for now. Its sole mission is to refuel manned planes in order to extend their range. But with a little imagination, the MQ-25 itself could become a long-range strike asset. Significantly, it has fifth-generation Stealth technology.

Boeing showed how the MQ-25 could become a strike platform. At a trade show in Maryland earlier this month, the firm displayed a scale model of the satellite-controlled MQ-25 with a pair of Long-Range Anti-Ship Missiles, or LRASMs, hanging under its wings. It’s a potent pairing.

The Navy’s concept for the stealthy MQ-25 is that one drone, out of a detachment of between five and eight drones assigned to a carrier air wing, would take off ahead of the manned fighters, fly out to a distance of 500 miles from the carrier – and then wait.

When a flight of four fighters arrives, the drone would offload 16,000 pounds of fuel via underwing pods and hoses, extending the range of each fighter to more than 600 miles.

Drone refueling helps the carrier air wings to claw back some of the striking distance they possessed late in the Cold War, when carrier decks were packed with far-flying Grumman A-6 Intruder bombers and F-14 Tomcat fighters plus Lockheed S-3 Viking tankers.

The A-6 could haul a useful bomb load a thousand miles . The F-14, which in the final few years of its career gained a secondary ground-attack role, could carry laser-guided bombs 600 miles. The S-3 could add a hundred miles or more to both types’ combat radius.

The Navy retired the A-6 in 1996, the F-14 in 2006 and the S-3 in 2009. Today Boeing F/A-18s and Lockheed Martin F-35Cs are the air wing’s main strike planes. They both range around 500 miles on internal fuel with a meaningful weapons load. 

The shrinking strike radius of a carrier air wing has become a crisis as Chinese anti-ship ballistic missiles have increased in range. Around 2010, the Chinese rocket force introduced a thousand-mile variant of its DF-21 anti-ship rocket. 

The DF-26, with more than double the range, appeared in 2016. The People’s Liberation Army Rocket Force possesses no fewer than 1,300 rockets, around 200 of which are the latest DF-26. Satellite pictures have revealed mockups of US warships set up as missile targets deep in China’s Gobi desert .

To strike at targets close to the Chinese mainland, an American carrier would have to sail well within range of the DF-26s. It would be no simple task for China to locate and track the ship – the carrier’s radar aircraft and fighters would keep aerial reconnaissance away, and there are serious difficulties in finding ships using satellites. Nonetheless, if China did manage to locate a carrier its escorts would have their hands full knocking down incoming ballistic missiles as the carrier launched and recovered jets. It’s a high-risk scenario.

But what if the MQ-25 kept all its fuel for itself – and carried the same missiles a manned fighter carries? In theory, an MQ-25 could range 2,000 miles from the carrier and then shoot its LRASMs at targets another 200 or 300 miles away.

Yes, the carrier would still have to sail within range of the DF-26: but only just within. As a bonus, losing a manned fighter often means losing a pilot. Lose a drone, however, and it’s just a financial write-down. 

To be clear, Navy officials long have mulled new missions for the 76 MQ-25s the fleet plans to buy. Maybe it could conduct reconnaissance and surveillance missions. Maybe it could team up with smaller and faster armed drones. Last year, Navy lieutenant Josh Hano wrote an essay urging the Navy to “evolve the MQ-25 to complement – not replace – manned aircraft.”

In displaying a model of an armed MQ-25, Boeing is just reminding people of these good ideas that already have their champions. And also reminding the Navy that it could act swiftly to arm the far-flying drones, as soon as the government is ready to pay for it – and as soon as the US Navy’s pilots, who have been resisting automation for a long time , are willing to accept such a move.
