One Metre

The International One Metre (IOM) class is a 1m long hull with 1.7m mast height and a minimum weight of 4kg. The class rules are very tight and limit yachts to 2-function control and 3 one-design rigs. Hull, ballast, draught and construction materials are also limited. There is sufficient freedom to allow different hull and fin/rudder shapes to be developed.
