[alberg30] Full Hoist Head Sail?

[sunstone]

From: sunstone <sunstone at idirect.com>

Listen to your sailmaker.  You will be pleased with the results.
As for rating, PHRF does not measure luff length and the base rating is
for a 150-152.9% besides.  A 135 would be a number 2 which will sparkle
in heavy air with the full hoist.   If you want to splurge on a great #3
get a 100% full hoist and you'll demolish the competition who are still
using the old working sail #3.

I do speak from experience, but have the sails cut fairly flat as there
is a lot of head stay sag to compensate for regardless as to how hard
you put on the backstay.   The biggest mistake modern sailmakers make
with these boats is to cut the sail too full and a large part of it is
because of the headstay sag factor.

Go for it.
