If you are turning, then there is an angle of attack on the foils which may or may not be in the correct direction. If y ou were put off by the complexity and expense of the hydraulic stabilizers, this design would be a good candidate for stabilizer fish on the booms, fish boat style. Howdy Jonathon:

I assume the foils are giving lift so the stabiliser fins are actually helping keep Avatar from rolling. Is there a minimum speed at which they start to help this way?
