Check Sail Shapes
Asymetricals can be made in different shapes to better fit the type of sailing you anticipate, that is, wind angle and strength. Last spring I was considering an asymetrical to supplement our symetrical and the one I like was called the Whomper by North Sails. It is not my intent to plug any particular sailmaker but to make a point here. Their web site for the Whomper showed the various sail cuts available which ranged from fairly close on the wind to broad reaching, and in a variety of weights to accomodate various wind strengths. If you've been watching your wind angles in the areas you sail then it would make selecting a sail for your use easier, in this case, at least.The Whomper is not cheap and I investigated some other lofts and found information on their sails, in some cases, to be very lacking. Several lofts had kind of a "one size fits all" sail cut and it was hard to get info out of them. Maybe this winter I'll look some more.When flying a chute be shure to have a bosuns chair handy in case the sail hourglasses! It can happen.
