These boats are light, responsive and fun to sail. This is the most popular of the four international classes and is sailed at most MYA clubs. The class rule is ‘closed’ and many aspects of design, materials and construction are restricted in an attempt to promote close competition. However the rule is designed to allow the DIY enthusiast some freedom to construct an inexpensive and competitive boat. The important speed related criteria of length, draught, displacement and sail plan are limited to a maximum of 1000mm, 420mm, 4kg and 3 prescribed rigs.
