it's stil amazing to me that you get good drive with a sail as flat as you described since on my monohull dinghy, when I flatten the sail (DH, OH, and vang) in higher winds the boat is SLOW
Jerry,
I had an interesting conversation with Glenn Ashby when I was having him make me a sail. One of the things he kept saying was that he was trying to make sails with low drag. Once you're fully powered up and then trying to depower, drag (from having too full of a sail) is what slows you down. After a certain windspeed, you're trying to decrease lift and increase aerodynamics to decrease drag.
