Talk to the guys at Nuclear Sails in Tampa if they are still around.
Like I said, I tried sailmakers including the one that made the sails, U.K.Who made the sails?
That would be where to start, they could tell you things like prebend and mast sag.
This is why I always say, pick the sailmaker that is going to give the best service to you.
Finally, someone with some numbers. Thanks!I recall base of 34 for the uppers and 30 for the lowers - good to about 12 knots
