The Asymmetric Sail has been
developed over the past few years
from sails used on some of the
modern Race Boats.

The Sail is of Tri Radial Construction
and really is multi-purpose, it can hold
its shape with the wind ahead of the
beam and powerful shoulders give
maximum projected area downwind.

There are 3 basic designs:-
a) Cruising with a maximum width of 170% of J
b) Cruiser racer at 175%
c) Race at 180%.
