Stewart, nobody stops you from building a wing and putting it on your F-16. I bet most F-16 sailors would love to go up against your winged F-16, I know I would. The only "but" in the equation is that you would not be allowed to race (or be scored, if evaluation was wanted) in F-16 class events. Open events would be just that, open. The F-16 class is a controlled development class. Intention is to control the arms race so cost is kept down. If the A-class goes ballistic with affordable and durable wings, we could always discuss the matter again. Nobody is against development, just control the costs of playing the game. The movable rudder finlet ban discussion was fronted by a very small group.. There will always be such discussion, unless you sail in a strictly one design class.
Timbo, I agree full heartedly with you. Having individuals spending time and money on experiments like this is fantastic.
