Good points Marcus.

In looking at how I sail my boat, the platform angle of attack changes constantly with the conditions. Up wind from a medium condition with flat water, I will drop the nose and try to drive it, while in a blow I will be back with the knuckle out going for speed and foil lift or keeping the beams clear when it is very rough. Foils as currently allowed try to keep a constant attitude. All changes is attitiude including normal wave pitching add drag to the platform. Even if adjustemnts were allowed no human is fast enough to to keep it perfectly alligned while sailing at the speed we go. I have some experience with this and have worked with a number of people who have tried them on larger boats and the reomendation from all is, "good luck if you decide to try"

Wouter, I have to disagree with your push on this issue. Insinuating that the F16 is not optimized without T-foils is BS. I am not saying that they do not work to some extent when developed properly like on the AO14 or the Stealth. I would hazzard to bet though that the fact John was sailing smoother than everyone else in Zaandvort's waves was due to his his sailing skill much more than the fact he had foils on his boat.

For the new sailor anything that is not off the shelf or automatic is a huge distraction to thier learning curve. These boats are complicated enough to drive. You would be a lot better off worrying about driving the boat than constant tinkering with appendages of questionable benefit.
