VERSION v1.0
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
race ready boat. For detailed
measurement rules and
information visit:

Note: these plans are very
new and untested, at your
own risk. But it should be
sweet! and sail like a
rocket. cheers. Bryn.

This faint pink line indicates the difference in hull shapes. I’ve
scaled the 65 up to 75 and overlayed the outlines. You can see
there’s more buoyancy in the front and the back. The keel and
mast step back a cm or so. The 65’s rudder would also be a bit
longer than a 750 to scale. This allows for the similar electrics
layout as in the book, simply change measurements hatch positions
need to change. These plans show the option to have conventional
wire stays or a swinging rig supported by a tube in the hull.
