Санфиш: История и особенности парусной швертботки

Personal size type of dinghy

The Sunfish is a personal size, beach launched sailing dinghy. It features a very flat, boardlike hull carrying an Oceanic lateen sail mounted to an un stayed mast. Sunfish was developed by Alcort, Inc. and first appeared around 1952 as the "next generation" improvement on their original boat, the Sailfish. In contrast, the Sunfish has a wider beam for more stability, increased freeboard and the addition of a foot well for a more comfortable sailing position. Sunfish began as a wood hull design and progressed to fiberglass construction just a few years after its introduction. Having a Lateen sail with its simple two line rigging makes a Sunfish simple to learn sailing on and to set up. Upgrades can be added to enhance sail control for competitive sailing, making the boat attractive to both novice and experienced sailors alike. Due to the broad appeal of the Sunfish, in 1995 it was commended by The American Sailboat Hall of Fame for being "the most popular fiberglass boat ever designed, with a quarter million sold worldwide" (at that point in time). Early in 2016, manufacturer Laser Performance moved production from Portsmouth, Rhode Island, US to China and boats were supplied to the 2016 World Championships. In 2017, Laser Performance (LP) announced the creation of a new governing body to manage the Sunfish Class, the International Sunfish Class Organization (ISCO), after the International Sunfish Class Association (ISCA), governing body since 1969, refused to sign a trademark agreement. In response the ISCA, still the World Sailing recognised Class Association, have announced rule changes which permit alternative suppliers to Laser Performance for some components. Today, the Sunfish brand name has become so widely known it is often misapplied generically to refer to any brand of board style boat sporting the characteristic crab claw sail. The design is currently manufactured by Laser Performance.

The distinctive low aspect ratio Lateen sail gives the Sunfish an anachronistic appearance compared with today's more familiar high aspect ratio Bermuda rig sailboats. However, this sail plan is not as old world as it might first appear. Using a lateen rig for this style boat shifts the advantage toward better performance in lighter air (less than 4 on the Beaufort scale) and contributes to it having good down wind characteristics. The hull’s very mild "V" bottom and hard chine make Sunfish a most stable boat for its size, along with enabling it to sail on a plane (hydroplane). Planing allows the boat to achieve a speed greater than theoretical hull speed based on length at waterline (LWL). Having a down wind performance advantage helps the Sunfish to achieve a planing attitude at lower wind speeds than its high aspect ratio sail plan counterparts. Designed as a water tight, hollow body pontoon, a hull like the Sunfish is sometimes referred to as "self rescuing" because the boat can be capsized and its cockpit swamped without threat of the boat sinking.

In 1945, Alex Bryan and Cortlandt Heyniger created the Alcort company to produce their first boat design, the Sailfish. Originally framing carpenters by trade, these two entrepreneurs began their sailcraft endeavors building iceboats as a sideline. A proposal to build a lifesaving paddleboard for the Red Cross came their way. They determined the concept unfeasible as it stood. An improved design sporting a sailing canoe sail rig did however strike a spark as a possible profit making venture. From that humble beginning the Sailfish was born. After Bryan's wife, Aileen Bryan suggested a boat with a small cockpit where she could put her feet, the design was updated to the Sunfish.

The first Sailfish were offered in the form of detailed drawings for the backyard builder or as a finished, ready to sail boat, built by the Alcort shop. In the course of growing their business, Cortlandt and Alex had the revelation to kit the boat by supplying pre cut pieces, all the necessary fittings, and inclusion of the sail thereby making backyard construction more appealing to an even wider range of would be boat builders. Sunfish first appeared as either a DIY kit or a finished boat. Of the two designs, only the Sailfish was originally a blueprint plan boat.

For the 1960 model year, Sunfish became available in a fiberglass version for the first time. Alcort shop built wood boats were phased out around the same period, however, the Sunfish kit boat remained available through the late 1960s. 1971 found a storage compartment added to the rear of the cockpit. 1972 model saw a revision of the rudder blade's shape, the rudder's gudgeon and pintle, a new shape daggerboard, and a switch to a Sunfish designed cockpit bailer. This was a turning point for those pieces of equipment, thereafter referred as "New Style" by owners of Sunfish from that era. Every few years, hardware and sometimes cosmetics and/or sail colors evolve, adding a piece or two of something more contemporary to replace outdated technology or style. In 1969, when AMF took over Sunfish production from Alcort, Inc., one of the expansion strategies was to form the Sunfish (racing) Class Association in order to qualify to race in sanctioned events. Recreational use boats may be modified as the owner chooses and need not conform to anything more than the local boating safety regulations in effect where the boat is sailed. In 1989 the fused deck to hull joint was changed from a ½" flat lip protected by an aluminum trim strip to the increased surface area of a rounded gunwale, now more securely bonded using a methacrylate adhesive specially suited for fiberglass. Sail geometry has changed on a couple of occasions, most significantly in 1989 when the "Racing Sail", still 75 ft2 "sail area", but with deeper draft, was made available as an option. In 2010 the last of the Sunfish's wood attributes were superseded when first the rudder and now this year the tiller were changed from wood components to fiberglass and aluminum respectively. The Sunfish was inducted into the American Sailboat Hall of Fame in 1995. Since its introduction in 1952, Sunfish has come under the stewardship of seven successive builders (see Sunfish Builder Chronology below).

For most One Design Class eligible boats, the number of boats built and the number of boats registered in the racing class are closely related. This makes the boat and the racing Class practically one and the same. The Sunfish is an anomaly to this more familiar symbiotic relationship. The Sunfish Class Association reported in 2001, Sunfish production had exceeded 300,000 boats. The registrar for One Design sailing in the United States, US Sailing, reported in a 2004 survey, Sunfish Class membership numbered 1,573. This does not mean Sunfish isn’t a preferred race boat. On the contrary, at 1,573 Class members, Sunfish ranks in the upper percentile of boats involved with organized racing in the U. S. It does, however, demonstrate the boat’s above average versatility to suit a broader range of sailing applications.

Recreational, "friendly competition" played a key role in establishing the renowned popularity of the Alcort boat designs. Events of past and present, such as the Connecticut River race, Seattle's Duck Dodge, and the Hampton Roads Sunfish Challenge & Dinghy Distance Race, now in its 10th year, serve as examples of the sort of fun Sunfish sailors have without getting too serious.

Sunfish sailors who are more serious about sailing competitions, but who do not have the advantage of a nearby Sunfish fleet, can race their boat against nearly any other make and model of sailboat in "Open Class" events using a handicap system. Sunfish have a base line Portsmouth handicap of 99.6.

One Design racing uses nearly identical boats so the competition is based purely on sailing skill. One Design Classes are watched over by a governing body who assure conformity. efn|ISCA Racing is in accordance with the Sunfish Class Rule Book
