Yacht Classes
INTERNATIONAL ONE METRE CLASS (IOM)
The International One Metre Class (IOM) is one of the most popular radio sailing class and has a strong International following. The International One Metre - International Class Association has taken over responsibility for management of the class and Australia was the first National Class Association recognised by the International body.
The class rules are very tight with three one design rigs permitted and restrictions on construction materials, overall and ballast weight, and draft. There is a maximum overall length of one metre and a minimum weight of 4 Kg. These rules are aimed at controlling costs and enabling the amateur builder to produce a competitive yacht.
The IOM is sailed in all Australian States and is Australia’s fastest growing class with over 500 boats registered.

DF95
The Dragon Flite DF95 is a new, relatively cheap, radio yacht that offers remarkable performance in a One Design Class. The "Big Brother" to the DF65 above, this class is an excellent starting point for those new to radio sailing, and offers more experienced skippers the opportunity to race in a One Design fleet. The complete boat with No. 1 Rig, almost ready to race (some assembly is required), including transmitter and receiver can be purchased online for around $500 from www.hobbywarehouse.com.au.
A CLASS
The Radio A class is the largest and most majestic of all the main stream radio controlled yachts sailed and raced in this country. The design dates back to the nineteen twenties when the boats would have been sailed free or later on with basic vane gear. The modern designs have used the changes in materials and equipment to produce lighter and faster yachts. The size can be up to around two meters long with a mast up to two and a half meters. Each hull has to be measured and the draft and weight recorded before the sails area can be worked out and made.
