Brad,

	Your article dealt with sail shape.  Have another article in your
hip pocket that deals with centerboard, diamond board and keel shapes and
areas?

Fred,

Last winter I shopped around for a new mainsail for my
S2 and got quotes from a half-dozen or more lofts. 
AirForce sails, part of SailNet, had the cheapest
price by a wide margin.  Cruising Direct -
www.cruisingdirect.com - came in second at a $100 or
so higher.   Eventually I sent it off to SailCare and
they cleaned it and made extensive repairs for about
half the cost of new.  Much less than half when you
consider the "features" the original Doyle sail had
the replacements didn't.  I've used them twice and
have been very happy with the results.  Get your sail
there early in the off season though, they are slow on
turnaround.

For those who are running a quart low on Bernoulli and
Newton, go to

http://onedesign.com/articles/article6.html

You have to give them some info to get the whole
article, just remember to uncheck the box asking for
e-mail updates from North Sails.  The seven-page
article on how sails work has just the right amount of
info and little math, both necessary to keep the
average attention deficit disorder pilot awake.
