The Sunfish is a personal-size, beach-launched sailing dinghy. It features a very flat, boardlike hull carrying a crab claw ("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.
