The Tornado class, use to dial in a sailcut to the predominate wind and wave conditions, has this started in the F18's ?
Are there any differences in sailshape between the sailmakers? Such as some sailmakers prefer flater sails than others? Sailcloth? Vertical distribution of draft/location? Maybe the sailmakers have come to a point where they are all generally the same shape?
If that kind of work is going on it's probably being done at the pro level in Europe. The US is still playing catchup when it comes to the F18 class (In my opinion).
The the biggest change I've seen in sail shape is the new fat head main as opposed to the traditional square top. I haven't seen any paneled or molded sails in the F18 class yet.
I'm not all that plugged into what the sail makers or the pro teams are thinking so take the above opinion with a grain of salt.
