Sunfish is a 13 ′ 10 ″ / 4.2 m monohull sailboat designed by Alexander Bryan/Cortland Heyniger/Carl Meinart and built by AMF Corp., Alcort, Pearson Yachts, and LaserPerformance starting in 1952.

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)

Although the earliest models were built of wood and offered as kits, the fiberglass version, first introduced in 1960, became the most popular recreational sailboat in history. As a result, there were many imitators.

Sunfish Builder Chronology 1952 - 1969 Alcort, Inc. (founded 1945) 1969 - 1986 AMF 1986 - 1988 Loveless & DeGarmo, dba, Alcort Sailboats Inc. 1988 - 1991 Pearson Yacht Co. 1991 - 1997 Sunfish/Laser, Inc. 1997 - 2007 Vanguard 2007 - Laser Performance Change in class rules permitted a new, slightly deeper daggerboard in the mid-1990’s.

Sunfish Class History

The Sunfish has its roots planted firmly in 1947 in Waterbury, Connecticut. Friends Alexander “Al” Bryan and Cortlandt “Cort” Heyniger (the Al and Cort in Alcort) pondered, “How to put a sail on a surfboard?” The answer involved a rejected design for American Red Cross waterfront rescue surfboards, leading to the Sailfish – a lateen rigged, flat-decked, plywood marvel. In 1951, Bryan’s pregnant wife found its flat deck somewhat uncomfortable. The addition of a cockpit and widening of the hull created the Sunfish. The logo was created by Heyniger, who traced a nickel and added fins, the tail and an eye. Early wood Sailfish and Sunfish were available assembled or as kits.

In 1959 the introduction of fiberglass and the low cost and ease of production led to the proliferation of Sunfish everywhere. Other improvements included aluminum spars replacing spruce, Dacron sails replacing cotton, ash replacing mahogany for tillers, resulting in increased speed, performance and reliability. Sunfish racing started almost as quickly as two or three boats came together – the first North American Championship was 1963, the first Midwinters was 1965. Bryan and Heyniger sold “Alcort Sailboats” to American Machine and Foundry Company (AMF) in 1969.

AMF/Alcort Division hired Steve Baker, and later Lee Parks, to organize events and racing leading to establishment of a Class Association. For almost 20 years Sunfish racing and AMF/Alcort were synonymous. In 1971 the original brass rudder fittings were replaced by the spring-loaded kickup system developed for the Minifish. Two daggerboard shapes were introduced in the 1970′s: the “new” style, which was swept back, had less area, and proved unpopular with racers, and the “Barrington” style, developed by the frostbite fleet, which proved equally popular as the original “round” style. As the Class matured, it applied to the then – International Yacht Racing Union and gained International Class status on January 1, 1984.

In mid-1985, Irwin Jacobs of Minstar Corporation of Minneapolis, Minnesota, bought AMF, intending to spin Alcort off, and saw no benefit in continuing to support the Class organization. On July 18, 1985 the International Sunfish Class Association assumed Class management from the manufacturer. On February 14, 1986 David Loveless and Jerry DeGarmo purchased the business, naming it Alcort Sailboats, Inc.

In October, 1986, Alcort Sailboats, Inc., agreed to work with Hans Fogh, then with North Sails, to develop a consistent and ultimate sail shape. At the same time, ultimate daggerboard and rudder shape development was launched. Due to many complaints from Alcort dealers to update the antiquated Sunfish hull design, a new modernized deck was also introduced. The improved deck configuration featured a 3 1/2 inch wider and 1/4" longer cockpit; a rolled flange gunwale (ala Laser) replacing riveted aluminum rails; non-skid on the deck on either side of the cockpit; and a standard hiking strap. In 1988 Loveless and Degarmo sold the company to Pearson Yachts of Portsmouth, Rhode Island, led by J. Gordon Clayton. Pearson acquired rights to the Laser separately.

By January 1989, today’s aerodynamic Racing sail was approved. It is approximately 10% larger in area with shaping fullness, has a 20% bigger window, a Cunningham cringle, is made of longer-lived and more evenly stretching cloth, and reduced equipment differences. the daggerboard had further design attention in 1989. In 1991, Pearson filed for bankruptcy protection. SunfishLaser, Inc., led by Peter Johnstone, was formed in 1991 from the small boats assets of Pearson, with primary funding from North Marine Group, parent company of North Sails.

Production control implemented by “SLI” resulted in hull weight consistency of 128-130 pounds. On January 1, 1994, today’s 3-3/4″ longer and foil shaped daggerboard debuted. It is liked for being forgiving to bad tacks, quicker, with less side slipping, at a cost of the sailor having to work a little harder in a breeze. This saved racers from constant build up and refinishing of wooden boards to get them up to tolerances. Sail America inducted the Sunfish into The American Sailboat Hall of Fame in 1995 in recognition of “a boat that has earned lasting recognition by fostering new enjoyment and growth in the sport of sailing through excellent design and production ingenuity.” In March 1997, Sunfish Laser, Inc. sold the Sunfish to Vanguard Sailboats Inc., led by Chip Johns and Steve Clark.  In 2007 Performance Sailcraft Europe and Vanguard merged to create Laser Performance.  The boat continues to be manufactured by LP to this day.

In 2001, with over 300,000 boats worldwide, the Sunfish’s 50th birthday was celebrated at Newport, Rhode Island. An out-of-the-box Sunfish was sailed at the regatta to the win.

The International Class organization continues its development. Sunfish gained Pan American Games status in 1999 and has been in the Games since. This has caused significant development in Pan American countries.  There are three continental and nine national championships regularly.  Efforts are ongoing for events for cruisers and racers alike, including a continuing commitment to an annual World Championship. Sunfish sailors stay dedicated to the “fun in the sun” mantra! – Gail M. Turluck

Sunfish Hull Speed...?

• Thread starter Simon Sexton

Hey Everyone, Good evening! Earlier this week, a friend and I had an interesting conversation about Sunfish. He says the hull speed is theoretically 6 knots, but I've gone quite a bit faster than that before on a Sunfish before a storm rolled in. Typically, when a sailboat exceeds its maximum hull speed, it runs the bow into the water and causes the boat to pitchpole or potentially sink. I suppose the force of the wind-filled sail could push the bow of the boat under the water if the sailor's weight wasn't situated properly aft. Any thoughts?

The hull speed of a displacement hull is 1.34 x the square root of the waterline length. If the loaded waterline length of your sunfish is about 13' (LOA is 13'9") then the hull speed is under 5 knots. However, a sunfish will go up on plane, so it's not really limited by the hull speed. It takes some extra energy to get a hull out of displacement mode, but it can be done. Many racing keelboat designs will do this as well, often under Spinnaker in a decent breeze.  

I think the HULL speed of a Sunfish is way lower than your friend says. BUT, the Sunfish is a PLANING hull and will exceed hull speed easily. David beat me. LOL

A Sunfish will ride the bow wave especially down wind. I raced a Sunfish against a 32' on the New River in NC. Anything north of a broad reach the 32 beat the pants off of me. But downwind, the 32 could not keep up. So is the SF capable of speeds in excess of "hull speed"? Oh heck yeah. But since the SF is such a small boat, speed perceived is perceptive at best. Unless one has some kind of measurement device then one can say the SF flies like an eagle. I think downwind the SF could reach 6+ knots. JMOH  

Will Gilmore

As everyone is pointing out, the term "hull speed" isn't a limit. It actually refers to a condition where the wake generated by an object's progress through the water is equal to the length water line (LWL). It is at that point that the efficiency of force to speed ratio begins to change dramatically. Any faster and the boat is having to sail up hill because it will be climbing its bow wake. This requires much more force than lower speeds when the hull is essentially riding flat. Hull speed is incorrectly referred to as theoretical. It's not a theory, it's a definition. The wave dynamics behind the term are well understood and consistent. Once enough force is applied that the hull makes the top of the bow wave, the hull is mostly out of the water and efficiency drastically goes up again. You can feel it in a powerboat. As the boat climbs her wake the engine labors. When she reaches the top of her bow wake, she flattens out and takes off. You have to pull back on the throttle to keep her from bursting suddenly into high speed. This is an indication of the increased efficiency of both reduced wetted surface and not having to expend energy displacing water, moving a volume of water out of the way. Sunfish are light for the sail area they have and they are flat bottomed. They are also a crab claw rig, which are one of the more efficient rigs. Exceeding hull speed should be fairly easy for them. They do best where the hull remains flat to the water. On a heel, they lose their planing shape. If using a GPS to measure speed, be sure to account for current because hull speed strictly refers to speed through the water, not speed over the ground. -Will (Dragonfly)

Hunter216 said: Will Thanks for that synopsis, I’ve read a few technical descriptions of this before but always got lost in the detail. Check this out if you want to think about “monohulls” planing!! Can’t wait until these become available on EBay <grin> Click to expand

Will There is an urban myth that there is a large cache of beer on the bottom of Lake Ontario where I grew up. One of the possible sources might be that there was a bunch of guys from a high school football team on a pontoon boat one day and a couple of the bigger guys decided they should run forward just as the captain went for a full plane to neutral. Of course I don’t have any first hand knowledge of said event!!!

Actually not a myth (well the story I told was!) In prohibition there was a steady flow of alcohol from Canada (Ontario) to USA (upstate NY). They used to hang the bottles over the side in grain sacks and when the Coast Guard would approach too close they would just cut them loose and let them sink. Such a waste!!!! Just saying  

Will Gilmore said: By the way, this is not typical. There are instances of old Clipper ships driving themselves under the water, but it usually takes much more than a building bow wave and heavy winds to sink a mono-hull. Catamarans are a little different story. They don't have as much forward flotation, but still, it would require heavy winds and a large wave to do that. Maybe catching a lobster pot on a fin keel could "trip" the boat under the right conditions. Surfing down a big wave into the trough with the wind really driving the sail could potentially do that to any boat. I sailed my hobie 18 into a 6' sea in 20 knot winds once. I had to put on a dive mask so I could see. We were under water almost as much as on top of it. However, never did we come close to pitch poling even though we were definitely exceeding her 5.6 knot hull speed. -Will (Dragonfly) Click to expand

All these years this discussion has persisted and still so much confusion. Back in the day, the theoretical hull speed formula was commonly used to determine optimal steam engine size for a given size boat. It's predicated on the fact that full displacement hulls move through the water, not over it.. they must push aside the water to make progress. This movement creates a wave that essentially traps the boat within its length. The phenomenon places a predictable limit on speed through the water that cannot be exceeded without an exponential increase in propulsive power, requiring massive increases in fuel consumption, weight and lost cargo space to accommodate them. A small flat bottom boat with a dagger board, such as the Sunfish, has no relevance to the theoretical hull speed discussion... it's designed to move over the water, rather than through it.

Sunfish – Race Version

$ 6,150.00

“The Sunfish is pure sailing—the sail in the wind, the board in the water, and you in the hull in between—one hand on the tiller, the other on the sheet and the wind in your hair. Pure sailboat racing, too. For the racing sailor, it is the essence of yacht racing. It was the first truly one-design boat, rigidly controlled by the manufacturer, with even the sails limited to one loft (for measured sails) and very little that could be done in the way of adding expensive go-fasts. No need for a new set of sails every year. No need to keep buying or changing expensive hardware to keep up with the latest sailing theory.” – Will White

Shoreline Sailboats is proud to be an authorized dealer for the Sunfish from Laser Performance.

LaserPerformance is the only builder of the original Sunfish.  We especially like the Sunfish for its versatility as a kid-friendly family boat, and an all out racing machine. We recognize the Sunfish as an amazing boat because it has such a long and rich heritage. Sunfish sailors are an incredibly diverse group who share a passion for one of the most popular boats ever conceived.

Most popular sailboat ever built:

Sunfish This is the classic boat you grew up with. World class racers such as Dennis Conner, of America’s Cup fame, and Gary Hoyt, who developed the Freedom class and won the first Sunfish worlds in 1972, learned to sail at the tiller of the Sunfish.

In Vermont clean water is a  paramount  issue as with other states. Conservation and reclamation  of resources keeps toxic materials from entering the environment. My Water reclaiming system reuses the water I use for wet sanding while the by-product is captured through a multi  filter medium . This ensures nothing will be going down the drain and into the ground or sewer systems. While I still enjoy being outside during the warmer months to do my initial washing and prep work, I still keep the heavy sanding  work inside in my containment wash booth. Also recycling these sailboats in many cases keeps them out of the landfills and on the water for many more years to come.
