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 (ISCA) 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. The International Sunfish Class Association – development In 1969 AMF was instrumental in forming the Sunfish (racing) Class Association. In 1984 the Sunfish Class became recognized by the International Yacht Racing Union, today known as the International Sailing Federation (ISAF). A year later the Sunfish Class went independent as the International Sunfish Class Association (ISCA) Sunfish gained Pan American Games status in 1999 and has maintained recognition in following years International Masters was held outside the United States, in the Netherlands, for the first time in 2005. There are three continental and nine national championships regularly. Sunfish fleets are active in 28 countries around the globe. Sunfish 60th Anniversary To celebrate 60 years of Sunfish, current builder Laser Performance designed a 60th Anniversary edition of the Sunfish to celebrate the diverse history of the boat and the sailors that love it. LaserPerformance also hosted a Sunfish 60th Anniversary Celebration at Noyes Pond in Massachusetts, the home of Sunfish designer Al Bryan, that gathered over 100 people sailing old and new Sunfish. Super Sunfish In the 1960s, a member of the New Canaan, Conn. Sunfish Fleet, John Black Lee, independently experimented with a conventional sail rig for the Sunfish. He developed a high-aspect ratio sail that worked on the Sunfish hull and christened his design the Formula S. The high aspect ratio sail plan has better upwind performance characteristics over the lateen sail, changing the boat's handling to point more like other Bermuda rig sailboats in its size. With this configuration, complexity of sail control is elevated by the addition of dynamic outhaul, downhaul, and mainsheet traveller lines. Lee's concept didn't interest Alcort, Inc. as a production model so he refit conversion boats independently and sparked organization of Formula S fleets. A few years after their 1969 purchase of Alcort, Inc., AMF revisited the idea of a high aspect ratio rig for the Sunfish. AMF did not choose to adopt Lee's Formula S design, they did however,
