International One Meter (IOM) Racing

Model sailboats with white sails sailing on calm water.

The International One Metre (IOM) is a class of Radio Controlled Yacht used for racing under World Sailing Racing Rules of Sailing. It is a measurement-controlled box rule originally created by the ISAF-RSD, now the International Radio Sailing Association (IRSA), in 1988 in an attempt to harmonise the various one meter rules created around the world. The IOM Class Rules specify a standardized sail plan and control of the other major performance dimensions (displacement, length, and draught) while allowing some freedom in hull design. The IOM is now the largest and arguably most competitive of all radio sailing classes.

Races are on Sunday Morning at the clubs private water details will be supplied on the venue, starting at 10:00am and finishing by 1:00pm
