This class is for yachts with a maximum size of 30 inches. Most are built from a
club produced glass fibre hull moulded from an old wooden yacht.
They can only use rudder control
and are not allowed to use a sail winch. If a winch is fitted it must be disabled before the race.
Yachts are raced around a triangular course, arranged to suit the wind direction. This is arranged such that one leg of the course is a beat into wind with another leg a run before the wind. The number of laps sailed are decided on the day to suit the wind strength.
