Sailboat racing is a major sport in the Detroit area. Lake Saint Clair is home to many yacht clubs which host regattas. Bayview Yacht Club, the Detroit Yacht Club, Crescent Sail Yacht Club, Grosse Pointe Yacht Club, The Windsor Yacht Club, and the Edison Boat Club each participate in and are governed by the Detroit Regional Yacht-Racing Association or DRYA. Detroit is home to many One-Design fleets including North American 40s, Cal 25s, Cuthbertson and Cassian 35s, Crescent Sailboats, Express 27s, J 120s, J 105, and Flying Scots. The Crescent Sailboat, NA-40, and the L boat were designed and built exclusively in Detroit. Detroit also has a very active and competitive junior sailing program.
