The one-design C Scow class created by Johnson Boatworks of White Bear Lake, Minnesota began sailing in 1905. Original, the boat and masts were made of wood and the gaffe-rigged mainsails were made of cotton. Through the years, hull shapes and materials have changed, but the critical formula remains the same: One hull, one large sail, two bilge-boards, and one helluva ride!
Until 1981, a total crew weight of 475 lbs during racing was strictly enforced. Today, there are no such restrictions, but the magic number for total crew weight remains around 500 lbs in the heaviest of winds, and less weight in lighter conditions.

The International Fireball was designed to meet a need – to the bridge the gap between the small “family” centre boarders and the larger more expensive classes. The designer, Peter Milne, an Englishman, had these motives: cheapness, simplicity to build, unequalled performance potential, price and waterline length, individual appearance.
The international laser, an Olympic Class sailboat, is quite likely the worlds most popular single-handed one-design dinghy, rivaled in numbers only by the sunfish.
The club 420 is the essential 2 person training dinghy used my the majority of youth sailing programs across the country. The boat is stable, fast, and this class association is very strong. The Club 420 features a single trapeze and spinnaker rig, while the club/collegiate 420 eliminates both for simplicity.
Fleets and regattas are widespread, especially on the east coast, and the 420 is also the choice of many high school & college sailing programs, including top teams like Boston College, Brown University, Yale, and more.
Originally launched in 1953, the 5o5 has withstood the test of time and is considered by many to be the best performing high performance planing dinghy ever built. This international class routinely attracts the world’s best sailors, and world championship events, held annually, almost always attract over 100 boats. A physically demanding single trapeze boat, the 5o5 rewards sailors who are smart, in shape, and love to tune. The boat offers those “who like to tinker” almost unlimited opportunities. The class rules, while strict, are fewer in number than most one design classes, allowing different foil and hull designs, mast sections, etc. Most all of the top sailors still go the same speed though, and that speed is fast.
