Mates: About 8 months has past since I started the sail trim forum. Probably, in that time, new beginners and intermediates have joined this great web site provided by sailboatowners.com. Sail trim is a very limiting subject. In other words, its not like nuclear research, which goes on and on. Once you understand the principles of sail trim, that's it. All you do after that is perfect your technique. With that in mind, I'm starting all over again from scratch with an explanation of draft depth, draft position, twist and angle of attack. So, if your interested in learing more about how to get 100% efficiency from your main and jib then hop on over to the sail trim forum and see what is going on. After all, we all have sail boats and while it is nice to know how to fix and repair them, wouldn't it also be nice to know how to sail them!?! Wasn't that why we bought them?
