The racing of radio-controlled yacht racing is governed by the same International Sailing Federation - Racing Rules of Sailing that are used for full-sized crewed sailing boats (with the inclusion of Appendix E, that introduces special rules to govern the radio-controlled sport). Vane controlled boats sail under their own rules. There are four international classes of radio sailing boats recognized by the International Radio Sailing Association (IRSA) who are recoignised by the International Sailing Federation are: (from smallest to largest). International One Metre (IOM) The IOM class rules specify a monohull of maximum length 1000 mm, with maximum draught 420 mm. There is a minimum weight of 4000 g, which makes homebuilding of competitive boats possible. The IOM has three one-design rigs. To keep costs down, hull materials are restricted to either wood or glassfiber, while masts and booms are restricted to either aluminium or wood. (International One Metre Class Association) International Marblehead A Marblehead has a maximum length of 1290 mm and a maximum draught of ca 700 mm, but no minimum displacement. Up to six rigs are allowed, the tallest being about 2200 mm. International Ten Rater International A Class (A), the largest of the international radio sailing classes. Other classes of international significance include the CR-914 the RC Laser, the Micro Magic, and the RG-65. The Bottle Boat is a low-cost alternative to these classes. Largely constructed from waste items (bin bags for sails and soft drink bottles for the body), it represents an environmentally friendly entry to the sport.
