More sailmaking terminology on the form than I am familiar with: dihedral angle...? And a good bit of technical detail on things like the sail shape that could result in really nasty sails
if the right numbers weren't input. (GIGO!) It looks like it might work, but I'd have to ask my sailmaker
friend first. Then he'd get upset at my taking the bread off his table, and I'd have to buy a new jib
from him, at least. (Getting a sailcover would add insult to injury.) If you have the machines to handle the material, it might be worth a try. You are right to see if someone actually IS using the software before spending on sailcloth.
