The rig stands at 942mm off the deck. You
could consider this a B-rig as the class rules
permit a mast that is 1100mm from the
deck. With a maximum sail area of 2250
cm2. This boat is designed for heavy wind
sailing, this gives it a wide range of
conditions with one set of sails. Different
sized rigs can be added by the individual
who wants to take it a step further,
which is encouraged by the designer.
The hull must be 650mm or shorter.
The hull must have a bowbumper
for racing.
These plans should produce a
