What was the problem as a light air sail? I should think a 150 would be
primarily for light air use.

My sail is 150%, for use in 0 to 15 knots of wind. What is a kappa cut

likely to be getting a Twaron (like Kevlar) laminate genoa, straight
cut panels, and for a reasonable price in comparison to having a
similar sail (With Kevlar-branded Kevlar) for about £200 more.


Sounds like a pretty good compromise. If the panels are
heavy enough to stand up to 15 knot winds, you'll be giving
up a bit of performance in very very light airs. But nothing
is perfect even if you carry two 150 genoas.


My original question surrounded the use of straight cut panels (I know
they have 'draft' cut into them!) vs. a radial cut, which to my
uneducated eyes would seem to allow more of a 3d-type shape to be cut
into the sail. The sailmaker seems to think it makes little difference
in this material.


It can make a difference in the weight of the sail... a
radial cut can use a lighter weight cloth. In a boat less
than 30' LOA or 9.2 meters, the weight saved is probably not
worth the cost. But radial cuts don't respond as well to
tuning either, their shape is mostly locked in. So if you
are an active type sailor then you would probably be happier
with the cross cut.
