Re-Rigging and Racing an Older 505 by Ali Meller with updates by Craig Thompson

Home » Library » Rigging and Project Archive » Re-Rigging and Racing an Older 505

Introduction

So now you have acquired an older 505, and you are trying to figure out how to fix it up, get it on the water, and make it more competitive. This article discusses some of the things you may need to repair, and what some priorities for improving the boat might be.

Determine Your Objectives

The first and most important thing is to set reasonable objectives. If you are the proud owner of a sub-7000 series hull number 505 (probably over 30 years old), no amount of effort is going to make your boat capable of winning the 505 North American Championship. There are lots of improvements you could do, but you have to decide how much money and time you are willing to invest. If your goals are to be competitive at the top levels of the class, perhaps a reasonable objective for a boat of this vintage would be to become familiar with the 505 by racing your current boat, and then selling it and buying a better one when you are ready. Dumping a lot of money into a boat of this vintage is not recommended.

For example, an older boat probably does not have a Waterat high-aspect centerboard and rudder, new Glaser or North sails, and a modern Selden Alto or SuperSpars M2 mast rigged to current specifications. You could add all that, a centerboard is over $1500, a rudder $800, a new suit of sails is about $2500, and a mast is about $1500. You could spend $6300 on your old boat, and you have not even started repairing it and updating the control systems! These investments are probably not reasonable for a sub-7000 series hull number boat, but might well be if you bought a used Superboat such as a Lindsay, Hamlin, or Waterat in the 6900-7500 hull number range (such a boat would also likely have more modern foils, sails, and mast).

There are lots of things you can do to make your old 505 better, and even more competitive without spending that kind of money!

Some of your priorities for improving an older boat might be:

• Make any necessary repairs
• Set up the boat to standard tuning sheet numbers
• Make basic control systems work
• Replace centerboard slot gaskets if necessary

The first priority is to repair any damage. Holes in the hull or buoyancy tanks need to be closed, and hi-load areas such as where the chainplates are fastened, and the mast step need to be repaired if they are damaged. Don’t worry about scratches, unless you can see fiberglass cloth.

Check the most highly stressed areas of the boat. Check the mast step, the shroud and forestay attachment points, the hiking strap attachment points, the transom, and rudder fittings and the centerboard and rudder. Have someone more familiar with 505s look over the boat, and point out any potential problem areas they see.

The Elvstrom bailers in the floor, and the centerboard bolt hole are frequent sources of leaks. Little is more discouraging than to be racing in light air in a boat that is slowly filling with water. Though less obvious, leaky buoyancy tanks can make the boat unsafe, and will slow you down if you are carrying any significant weight of water in them.

Fixing the boat so it won’t sink is important; your life could depend on it! If you sail the boat with leaky tanks, and you capsize, water will collect in the tanks. Long before the boat has lost buoyancy, it will be harder to sail, and less stable. You will probably capsize again, getting more water in the tanks, making the boat all but impossible to keep upright.

Leaks can easily be fixed – the key is to find them! Buoyancy tanks normally leak where holes have been drilled for fittings, or at the tank/hull joins. The most common approach is to use a vacuum cleaner that can blow air. You pull out the drain plug, sponge soapy water all over the tank, and then very gently bring the nozzle of the vacuum cleaner close to the drain plug opening. Do not simply butt the nozzle right up against the drain plug opening. You could blow the tank off the hull. Gently push air into the tank, and watch for bubbles forming where air is escaping – those are leaks. Leaks, where fittings are mounted, can be fixed by removing the fitting and re-installing it with a silicone seal, or if the mounting holes are worn, filling them with epoxy and then re-drilling and re-installing the fittings. Leaks between the hull and tank join can sometimes be fixed by cleaning and roughening a two-inch wide strip over the join, and then epoxying two-inch fiberglass tape over the join.

est your leak repairs, by capsizing the boat in the water, and sitting on it to keep the tank immersed for ten minutes. If you have more than a cup or two of water when you check the tank, look for more leaks!

Leaky bailers can be replaced. You simply need to describe which model of bailer you have to the chandlery where you are purchasing a replacement. Most of the time, the fixed portion of the bailer is fine, but the moving portion and/or the seals between the moving and fixed portions need to be replaced. The seals are separately available. If the moving portion has to be replaced, buy a complete new bailer, remove the moving portion and replace the one in the boat with it. I use soap to lubricate the bailers enough for me to remove and then install the inner moving piece (you have to bend a small stainless steel tab at the back of the moving portion to get it in or out).

Leaky centerboard bolt holes can be repaired by buying new rubber washers, and ensuring that the bolt fits tightly in the bolt hole. If the bolt hole has become enlarged, you can repair it by taping over the holes on the inside of the centerboard trunk, filling the holes with an epoxy filler mixture, and then drilling a new bolt hole. Be careful to drill the new hole “squarely” in the boat. Check your sail maker’s tuning guide and consult with active local fleet members for the preferred CB bolt measurement, and fill the old hole and drill a new one in the preferred location if necessary.

Set Up the Boat to Standard Numbers

Check your sail maker’s tuning guide and consult with active local fleet members to determine the basic “fast numbers”. Set your mast step and CB bolt hole where the tuning sheets indicate (you may have to move the bolt hole), and then tension the rig and ensure the mast is straight side to side and is correctly raked. Determine if you can set your jib leads close to the location described in the tuning sheets.

Assuming your boat has a jib halyard rather than a stuff luff , you can control rake by easing or tightening your jib halyard. Do you have adjustable shrouds? Most older boats do not. If you have an adjustable forestay/jib halyard AND adjustable shrouds, then you can consider the forestay to be the rake control and the shrouds to be the tension control (yes, I know they both alter both, but this is sort of a first approximation to simplify things).

Try not to think of the mast ram as a mast rake control, but rather as a mast bend control.

The most important setting is the “standard” 25′-8″ base rake setting. Assuming you do not have adjustable-while-sailing shrouds, then 25′ 8″ rake” is where you want to set up the boat. You can always change your shroud length on shore before the race if you are expecting strong wind.

You set up at 25′ 8″ by hoisting the tape measure on the” main halyard to where you normally hoist the main. Tension the forestay/jib halyard until the shrouds are somewhere around 300-450 lbs. (I use the Loos tension gauge to check this on the shroud, the forestay is usually looser than the shrouds), and then sighting up the mast to see if it is straight sideways and fore and aft. If it is not straight sideways, the shrouds may not be the same length, or the mast gate or mast step may not be exactly in the center of the boat. You may need to adjust one or the other shrouds to get the mast to be straight sideways. To straighten it fore and aft, use some ram (you can use wooden blocks in the mast gate) to push it straight. I do not sail with a straight mast, but I measure rake with a straight mast (makes it easier to reproduce settings). Now, once the mast is straight sideways and fore and aft, and you’ve got close to the right tension on the shrouds. Measure the rake. You almost never want to have a number greater than 25′ 8″.” Some 505s go to 25′ 9″ or even 25′ 10″ for light air, but most don’t.

If shrouds and forestay/jib halyard are adjustable, alter them to get to the 25′ 8″ measurement. whenever you alter anything, check the mast is still straight fore and aft, and use the ram to get it back to straight. Unfortunately, you can spend a little time easing one control, tightening another, checking tension, then checking mast bend and changing the ram, then checking rake and realizing you’ve gone too far, and so on.

Even if your shrouds are not adjustable while sailing, you probably have some adjustment available on chainplates, so you can change shroud length on shore while you are checking rake. To increase rake (raking aft, reducing the rake number) for a windy day, you would have to easy everything, undo the shrouds from the chainplates, shorten them by a hole, and then tighten the jib halyard, adjust the ram to keep the mast straight, and check the rake measurement. To decrease rake (raking more upright, increasing the rake number) for a light air day you would ease everything, lengthen the shrouds, tighten the jib halyard, adjust the ram or blocks to straighten the mast, and check the rake measurement.

There are different approaches taken by top North American 505 sailors, depending on which sails you are using. Some require lots of rig tension (similar to heavy air settings) to pre-bend the mast and flatten the sails. A mast pre-bender or ram-up control can also accomplish this. Some flatter mainsails allow you to sail with a looser rig which will “soften” the jib luff.

505s rake the mast aft to depower in heavy air. With non-adjustible-while-racing shrouds you would accomplish this by shortening the shrouds on shore, prior to launching. We rake as far back as 24′ 8″ or even more back.

Key Controls

A modern US-rigged 505 can have a sophisticated array of controls. While no boats have all of these; current boats have some of the following (some of these are mutually exclusive):

• Main cunningham
• Jib cloth tensioner (jib cunningham)
• Boom vang led to both side tanks
• Main outhaul
• Adjustable forestay – while racing
• Adjustable shrouds – while racing
• Adjustable mast ram
• Adjustable mast pre-bender
• Adjustable jib leads (fore and aft or up and down)
• Adjustable jib leads (inboard and outboard)
• Lifting Centerboard pin
• Centerboard pin adjustable fore and aft
• Adjustable shrouds and forestay led out to side tanks
• Mast ram led out to side tanks
• Spinnaker pole topping lift

An older boat needs the basics, but most probably is not going to get all of these control systems. The most important controls are:

• Rig tension – usually a jib halyard
• Rake adjustment – some way to alter shroud length – chainplates or turnbuckles
• Boom vang control led to each side
• Mast bend control – could be as simple as wooden blocks in mast gate

Rig Tension

You need enough mechanical advantage to carry 500 pounds of tension on the shrouds, or whatever the hull boat can carry. This can be attained with a magic box, a lever, or the best choice, a cascading block system. Whatever system you choose, you need enough travel so you can get the rig tension you want throughout the rake range, and still have enough slack to hook up when you hoist the jib, especially when you have shortened the shrouds for heavy air.

Rake Adjustment

If you have easily adjustable shrouds, great! If not, you need to be able to adjust shroud length somehow. A typical shroud system has a “u bolt” on the rail, with a chain plate adjuster connecting the eye on the bottom of the shroud to the “u bolt”. The holes in the shroud adjuster allow you to move the cotter pin holding the shroud eye – and the shroud – closer or further away from the “u bolt”. Moving the cotter pin and shroud eye closer to the “u bolt” shortens the overall shroud length, and rakes the mast aft. Moving it further away from the “u bolt” lengthens the shroud, making the mast more upright. Another simple shroud length adjustment system is to put turnbuckles between the “u bolts” and shroud eyes. Remember to adjust both sides the same amount when you change rake!

Vang Adjustment

After the main sheet and spinnaker sheet, the vang is probably the control you will use the most. It should have enough mechanical advantage (mine is 18:1) and should be led to where you can reach it while hiking or sitting on the rail. Lever vangs have fallen out of favor, as they do not have enough travel. In heavy air, you will need lots of vang upwind and will be dumping vang downwind while carrying the spinnaker. A lever vang cannot give you the travel you need to do this. Most top boats now use a cascade vang system. Mine starts with a wire dead-ended on the becket of a strong block attached to the boom. The wire runs through another block shackled to the base of the mast, back up to the first block (that had the becket), and ends on a triple block. A double block and two single swivel blocks are shackled to the mast, a little above the second wire block. A thin Marlow line is threaded through the blocks, starting and ending with the swivel blocks. The use of swivel blocks allows you to turn the ends of the control line to thru-deck blocks installed in the bulkhead, next to the hull/tank join, and from there, aft along the hull/tank join to cheek blocks mounted in the tank, which turn the control lines up to the cleats bolted into the seat tanks.

Mast Bend Adjustment

Modern North American 505s use mast struts, fixed on the foredeck above the watertight bulkhead and fastened to a “car” sliding on a track riveted or bolted to the mast, roughly at gooseneck height. Pulling down on the car forces the mast aft at gooseneck level while pulling it up forces the mast forward inducing bend. This system works very well, but the same effect can be had by using wooden blocks in front and behind the mast at deck level. The mast is forced aft to straighten it for more power, is allowed to bend forward to depower, and is forced forward to pre-bend for flatter sail shape in light air. In addition, the mast is prevented from being pushed too far aft by pressure from the spinnaker pole on a heavy air reach. This last point is important when tight reaching in heavy air. If you do not have the means to prevent the pole straightening – or even inverting – the mast, when a puff hits, the spinnaker pole will start bending around the forestay and the main will become fuller, both undesirable.

Main Cunningham

The cunningham is an important sail shape and depowering control. An elegant solution is a hook made from a shackle with part of one arm sawn off, swaged to a 2:1 mechanical advantage, which ends in a thin control line and a cleat on the centerboard cap. Installing a single block behind the cleat, allows you to pull on the cunningham line from any direction and have it cleat automatically.

Replacing Centerboard Slot Gaskets

Slot gaskets prevent water from swirling around – and out the top of – the centerboard trunk. Old gaskets that have stretched out do not do this well. Gaskets also “fair” the hull/centerboard join. Most top North American 505s use slot gaskets made of two strips of folded over sailcloth tape. Mylar is inserted in-between the two layers of sailcloth, for the back half of the centerboard trunk. The two gaskets are sewn along the long open edge and are sewn together for about 1/2 inch at the front. Most 505s have two long and one short aluminum strip that holds the slot gaskets to the hull.

Remove the aluminum strips, then mount the new gaskets at the front of the centerboard trunk with a couple of screws. I punch a hole in the back of each of the gaskets – behind where it will be cut off to fit the trunk – and use some line to stretch the gaskets – I tie them to the rudder fittings. Then drill through the existing holes in the aluminum strips, and put screws in all the holes. If your gaskets were over-wide – most are as delivered – you can cut them flush with the aluminum rails after they are installed.

You cannot turn an old boat into a superboat, but you can probably make it a lot easier to sail, and faster, by making necessary repairs, setting it up according to the tuning sheets, and making sure that you have the basic control systems in place.

You may have heard that 505’s are some of the most well-made dinghy’s around. Many 505’s can stay competitive for an indefinite period of time when well cared for. Some older 505’s were not built as well, and may not be worth spending time and money on to get back on the race course. This page is organized in a way to help you determine which boat is right for your own 505 sailing goals. Visit the list of builders for more information on all the various 505 builders throughout the years. Also, hull numbers are sequential, and are issued upon initial measurement after the boat is built. The minimum weight of a 505 (weighed with all equipment required for racing except sails) is 127.4kg or 280.9 pounds. Many boats have lead corrector weights (50% located at front of CB trunk, 50% located at rear of CB trunk) to bring the boat up to this minimum weight.

The used boat ads on this page are organized based on the following classification scheme:

The Surtees Service Award was dedicated at last year’s NA’s to commemorate outstanding service to the American Section. The inaugural award was presented to Ali Meller.

It is a pleasure to introduce the 2003 winner of the Surtees Service Award – Jesse Falsone.

As all of you know, Jesse is the epitome of the “go-to guy” for our Class. When a valuable role within the American Section needs to be filled, Jesse has never been afraid to put his money where his mouth is and step up to the task.

In the eight years that he has been in the Class, Jesse has served as both Class Secretary/Treasurer, and President of the American Section.

Upon “retiring” as Class President, Jesse took on the role of Tank Talk Associate Editor, and over the past few years, no one has contributed more material to Tank Talk than Jesse.

Jesse is an incredibly focused competitor who has always found time to pass his knowledge along. After working for years to become one of the top 5o5 crews in North America, Jesse published a compendium on “High Performance Dingy Crewing,” utilizing both his knowledge and that of other top NA 5o5 crews. This pamphlet runs 33 pages, and is literally a textbook of how to climb the learning curve for a 5o5 crew. Any skippers out there up to the challenge?

Jesse has set the bar for 5o5 class members, dedicating a superhuman amount of time & effort into making the American Section the solid organization that it is today.

Although he is taking a well-deserved break from the 5o5 and cannot be here today, let’s have a big round of applause for Jesse.

Ted Ferrarone

I’m very proud to have commissioned this new service award bearing the name of one of our most distinguished members: Dennis Surtees’. Dennis is a legend in this class, both for his outstanding performance and for his superlative service. I’m equally proud to have Ali Meller as the first recipient. Ali has served in so many capacities for this class, most of which many of you don’t know about or may have forgotten. Ali has been fleet captain in the US for two different fleets (maybe more in Canada?). In one of these he was largely responsible for the creation of this fleet at a new club. He served as VP of the American Section, Editor of Tank Talk, VP of international (an office created for him), and is now completing his term as President of international. As webmaster, Ali took the 505 web page and made it the most informative class page on the Internet. US Sailing used our web page as an example of what a great class web page should look like. Ali was also instrumental in introducing countless people to the 505 through personal communications and through sailing time.

Ali’s leadership came along at a crucial time for the 505 class. In the early 90’s we were a class teetering precariously on the seesaw of success and failure. Our numbers in the US had steadily declined, and the class lacked direction. Ali was the catalyst for our resurgence, and a large reason why we all enjoy fine competition today.

Simply put, nobody in the world has put more into the 505 class in the past decade than Ali Meller.

Ali, on behalf of the 505 American Section, it’s my honor to present you with the Dennis Surtees Service Award for 2002.

“I nominate Bill McKinney and Stine Cacavas for the Cahn award. Bill has been with the San Diego for over ten years, and is the guy who always spends regattas in good spirit, with lots of humor, humbleness and grace. And style. After coming in from the race course early one day in Santa Cruz, while sitting in his chair, he greeted every sailor at the ramp with a cold Corona with lime. Yes, his regatta kit includes chairs, a cooler on wheels, and a cutting board. Stine has been sailing with Bill for a few years now, and while she shares Bill’s positive attitude, she also brings a new level of competition to the team. They competed in the 2010 worlds in Denmark sailing Fever Pitch, Dave Cahn’s own Lindsay. For the 2012 worlds in France they upped their game, buying a newer Waterat. I take this as a good sign that they will continue to favor us with their company for many years to come.”

Aaron Ross, USA 7156

Nominated and presented by: Mike Martin

The Dave Chan award goes out to the individual or team that expresses sportsmanship in the unique way of 505 sailing because they love 505 sailing. The award is not necessarily for the guy that wins all the races, but the guy you would most like to have a beer with at the end of the day.

These guys fit that description perfectly. They both came into the 505 picture from illustrious lead mining careers. After the first day of proper breeze in a 505 they were hooked. Since then they have enjoyed attending many of the events in northern and southern California. At the end of the day they are always thrilled with whatever they experienced and learned on the water. They are always willing to lend a helping hand despite the fact that they are usually involved in some major repair project themselves. It is always a pleasure having these guys around both on and off the water and we would all have more fun if we adopted their attitude. That is why this year the Dave Cahn award should go to Brad Wheeler and Bill Mais.

As most of you know, the Dave Cahn trophy was created in 1998, in memoriam of Dave Cahn, and his special brand of sportsmanship. Past winners have included Eric Willis/Wendy Herzburg, Barney Harris, Dan Merino/Bill Jenkins, Henry Amthor, and in 2002, Stuart Park.

Please give a big round of applause for the winner of the 2003 Dave Cahn Trophy: Paul Von Grey.

Paul’s nomination for this award was so excellent, that we will just read it to you:

“I would like to Nominate Paul Von Grey of the Pacific Northwest Fleet for the Dave Cahn Trophy. Paul has virtually single-handedly (no pun intended) been the motivation for the resurgence of the 505 fleet in Washington. He has helped push attendance at regattas from an average of three boats to a recent high of 16. He regularly rounds up sailors following races to debrief on successful and unsuccessful strategies and rigging tips. He serves as the unofficial parts warehouse for most of the sailors in Washington and probably has contributed parts, time or rigging advice to a majority of boats in Washington, Oregon, and British Columbia. He helped obtain a container of highly competitive boats that have raised the quality of racing dramatically. Whether you are a current 505 owner who needs to locate crew or a prospective 505 competitor who wants to go for a test ride, Paul is the guy who helps make the connection. He successfully poaches new 505 sailors from other fleets at regattas and every new sailor in the local fleet has probably been pointed to Paul as the guy to talk to about 505’s.

The Pacific Northwest fleet is a knowledgeable, friendly and helpful group of people and the description above could apply to every person in the fleet, however, no person embodies all of those qualities as completely as Paul.”

Let’s give another round of applause for Paul Von Grey!!

Nominated by Dave Stetson

Jesse, I wish to nominate Graham Alexander for an honorary life-membership in the class.

Graham first became a 5-oher around about 1967 and he has been one ever since. I know only a few on this side of the pond with that kind of longevity in the class. He has owned at least six boats, beginning with a 2XXX series boat; he currently owns two, a 45xx Rondar rigged to race with other classics, and Parker 7685. Not only has Graham been loyal to the class with his presence, he has been one of the class’ most ardent recruiters here in the Midwest. Within two weeks of the day I moved to Columbus in 1985, he was in my kitchen pushing me into the fray, getting me onto the boat, and helping me to find a crew slot. He has introduced dozens of people to the boat during the 17 years I have been around to watch.

In addition to recruiting, Graham has been the organizer of the class in Region 3 for as long as anyone can remember. Ki Kaiser and Graham have worked together ensuring a variety of regattas and spreading the word. He was the formal Midwest coordinator for most of the years since 1970.

Graham has been extremely generous with his time helping people to buy boats, helping them to rig them well, and helping to repair them when they broke. He has loaned his garage, his tools and equipment, his hands, and his expertise for fiberglass work, vacuum bagging, and rigging. Each winter, he has taught Sunday-evening courses on racing rules and tactics, crewing and helming skills to groups of local sailors, including newbees and hardened veterans.

Graham has been one of the true fixtures in the class and he has been one of its best public-relations specialists. Through his energy and love of the boat and the class, he has kept 505s in the Midwest and has kept Fleet 17 alive at Hoover Yacht Club. He may not be the most jolly of 505 sailors because he takes his sailing very seriously. It is integral to his core as a person and his love for the class is infectious. Because of his dedication and generosity, I believe he is as close to a life member as one could come.

Nominated by: Mike Martin and Ryan Cox Presented by: Dennis Surtees

Most of the time when we think about an award for service to a class we think about class officers or people that have volunteered their time in a very broad manner. Howard has served this way in the past by being an international class president but that is not why he deserves this award. Everyday Howard provides service to the class on a much more personal level.

The services that he provides range from straightening a mast, to loaning out his coach boat out free of charge, or letting people use his tools or even his entire garage. If you don’t know how to fix something on your 505, you need a tool or a part, who is the first person that you ask?

His services are organizational as well. Howie is always thinking of ways to better himself and always passes what he learns on to the fleet, even if it is one boat at a time. The Long Beach fleet would simply not exist without Howie. Every year howie takes the lead in organizing our weekly practices. A few years ago Team Tuesday was 1 or 2 boats, this year we often see 7 or 8.

Howie has also provided a huge service to the development of the equipment that we use today. 25 years ago he built molds and long lasting Honeycomb Kevlar boats that are still competitive today. Howies funding of the blade development program resulted in production centerboards that cost every one else much less than the developmental price that he paid.

There is no one more valuable to our fleet than Howard. So whether or not he wins this award, next time you see him, just say “Thanks Howie”!

505 Deck Layout

To get the most out of the 5o5 in lighter air, teams have begun to pull the boom to windward. Pulling the mainsheet bridle across is now an additional step you need to master. This simple system helps makes it easier to have perfect tacks. There is nothing to cleat or uncleat. As you roll tack, pull the center of the bridle control line where it crosses the centerboard trunk. When you get to the new high side, you'll find the bridle is now offset on the windward side. Friction contributed by the bridle's travel over the side tank, combined with the tension from the shockcord between the two T-18 blocks in the back, lock it into its new position. The system is easily adjustable as hand tension will overcome the shockcord and that friction.

Dual Pole System

Gybing the 5o5 has never been easier now that most boats are running two poles. To begin the gybe, pull one of the two pole-out lines (cleated under the gooseneck on a pivoting exit block) until the inboard end hits the mast. When it's time to gybe, simply uncleat that pole-out to snap the pole back into place alongside the boom. Then gybe the boom, give the new weather pole-out line a pull, and you're off and running.

Shroud System

The 5o5 rig is highly adjustable, allowing the boat to perform at optimum speed in all conditions. For more shroud tension, the crew pulls a single line and both shrouds tighten equally. Top teams are also attaching Small Boat traveler cars to the shrouds. The cars mount to tracks on the rail, allowing the shrouds to be eased to get the mast tip further forward for extra drive on the runs.

Class History

A powerful sail plan and easy-to-adjust rig that can be adjusted while racing ensures this challenging doublehanded trapeze dinghy performs superbly—from 30 knot smokers to light-air breezes. Designed in 1954 by Englishman John Westell, the 5o5’s sail plan and hull shape are strictly controlled, but rigging layout, spars, and the foils are more liberal, allowing the boat to be set up in a number of ways to suit racing preferences. Physically demanding in a breeze, most combined crew weights average around 340 lb.

Hanse 505 is a 50 ′ 2 ″ / 15.3 m monohull sailboat designed by Judel/Vrolijk & Co. and built by Hanse Yachts starting in 2012.

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)

Hull length: 14.85 m / 48.75’ Shallow draft: 6.6’/1.98m Displacement with shallow keel: 14900kg / 32,849lbs.

This Chinese Luxury Hybrid SUV Combines a Tank, a Bentley, and a Boat

What do you get when you cross a Land Rover Defender, a Bentley, and a boat? The answer is the Yangwang U8, an enormous hybrid SUV from the upmarket sub-brand of Chinese electric car giant BYD that can drive on—yes, on , not in—water.

The Land Rover bit is obvious thanks to the U8’s chunky styling, massive scale (at 5.3 meters, it’s as long as the Defender 130), and claimed ability to drive just about anywhere due to four electric motors and clever hydraulic suspension.

The Bentley factor also doesn’t take much explaining, since the U8’s cabin takes a big step up from the plastics and synthetic leathers used in BYD’s lesser cars like the Seal and Atto 3 . Here there are acres of napa leather, plush headrests, massage seats with heating and cooling, and open-grain Sapele wood veneer. There’s even a storage cubby beneath the central armrest that can be cooled to –6 degrees Celsius or heated to 50 degrees Celsius (21 to 122 degrees Fahrenheit).

Less Bentley but more BMW is the amount of tech onboard, including three displays spread across the dashboard and two more to entertain rear-seat occupants. The central 12.8-inch OLED touchscreen is curved vertically and flanked by a pair of 23.6-inch displays facing the driver and passenger. There’s 50-watt wireless phone charging and a 22-speaker sound system with support for Dolby Atmos.

Works on Water …

Now for the boat bit. Ready? BYD says the U8 can wade through water up to 1 meter deep—100 millimeters more than a Defender—and then after that, should the wet stuff get deeper, it floats.

You could, of course, argue that any car temporarily becomes a boat when unexpectedly introduced to water, but the Chinese company actually means it.

Instead of promptly ingesting a few gallons, flooding the cabin, and expiring, the U8 calmly shuts down the engine, closes its windows, switches the air conditioning to recirculate, opens the sunroof as an emergency exit, and keeps right on going. There’s no rudder or outboard motor, but BYD says the U8 can sail at 1.8 mph by simply spinning its wheels.

Watch the U8 being tested sailing through watch in boat mode. Be warned, it can only do this for 30 mins.

Boat mode is only intended for use in an emergency, like flash flooding, and BYD says the U8 is designed to do this for just 30 minutes. It isn’t clear what happens on extended voyages.

Drivers/skippers are also urged to take the U8 to a workshop for an inspection after unintentionally (or perhaps intentionally) taking their luxury electrified 3,460-kilogram car/yacht into the water. This might make the U8's bathing abilities sound like an unnecessary feature, but in countries prone to extreme rainfall and flooded roads, building a car capable of floating back to safety isn’t as strange as it sounds.

… and on Mountains

Back on dry land, the U8 promises to be a seriously capable off-roader. Intelligent drive modes send power and torque to whichever corner needs it, and because there’s an electric motor for each wheel, the U8 can perform a tank-turn, spinning on the spot by turning its left and right sides in opposing directions. On asphalt it’ll create enough friction to buy the Michelin Man a new holiday home, but it’s a smart way of negotiating tight spots while off-roading.

We mentioned earlier how this is a hybrid, but its drivetrain doesn’t work in the conventional sense. While there's a turbocharged, 2-liter petrol engine, it isn’t connected to the wheels. Instead it acts as a range-extending generator and sends its power to the U8’s modest 49-kWh battery pack.

BYD says the U8 will manage 112 miles on electricity alone or 620 miles when the engine gets involved. The four electric motors combine to produce a frankly absurd 1,200 horsepower, making the U8 the world’s most powerful SUV. And BYD says the near 4-ton car accelerates to 0-62 mph in just 3.6 seconds.

Tech Specced

The flagship U8 Premium Edition supports fast DC charging up to 110 kW. Now, that doesn’t sound like much in a world of 320-kW Porsches , but the Yangwang’s relatively small battery means charging from 30 to 80 percent takes a claimed 18 minutes. The engine can be used as a vehicle-to-load (VTL) generator, delivering up to 6 kW for charging electricals and powering appliances.

As you’d expect in 2024, the U8 is packed with driver assistance tech, too. Those three taxicab-like bumps on the roof are lidar units for creating real-time 3D scans of the road ahead. There’s also 5-millimeter wave radars, 14 ultrasonic sensors, and 16 cameras. BYD says semiautonomous driving on highways and City Navigation Autopilot will arrive via future over-the-air updates.

The U8 is priced from the equivalent of £120,000 (around $149,000) in China, where it is available right now. Sadly, BYD has not yet committed to selling the car in Europe and the UK, or even to bringing its premium Yangwang brand here. But when you consider European drivers' newfound willingness to try novel car brands, paired with a plush SUV market already offering the BMW iX , Mercedes G-Class, and Range Rover , the thought of U8s tank-turning in tight city streets or wading with confidence through flooded fords either side of the Atlantic doesn’t feel far from reality.
