No matter what foils you put on, straight put on at an angle or curved with or without twist the thing I don't get is how do you control the foiling (even if it is only partial foiling).

It seems to me you need a way to dynamically control the stance of the boat to avoid the F20 carbon "jump", or the "dive dive dive" if by mistake you start to pitchpole. I understand that weight placement and how far you put the board down will help but it will never be as reactive as the combination throttle tiller/active wand of the moth, the trifoiler palpers or the self regulating foils from the hydroptere/white dragon.

IMHO the next chapter in multihull foiling is not in curved boards, it's on how you control them. The more speed you have, the less angle you need, so as you accelerate something has to change somewhere to keep the lift under control.

Anyway, I'm not even sure why this discussion is in the F16 forum: F16 rules prohibit foiling in multiple way so if you want a foil fix hit the gym first then get yourself a moth or a rs600 (foiling on the wire!).
