Thanks Dave

Great work on the foilers .

4 extra hands or an on board comp/ system to control foil pitch and flap control and amount of lift does seem a bit expensive

Agree with the fixed concept , are asymetric canted foils -boards the answer ,-or are the sym. sections best .

What is the lattest development on foil section -

found this ,but it seems dated already .
