In some vids, it looked like they had a canting mast, but I'm not sure. I am fairly sure that the main hydrofoils are engineered with tapered chord and possibly some foil twist to naturally control the rise and fall of the plane thru the water (e.g. when the plane goes up, less lift is generated by the foil and so it goes back down). Also, the orientation of the foils (inward at 45 deg or whatever) tends to create stability because, when the boat heels to one side, that lowside's foil becomes more horizontal thru the water and produces more upward lift while the highside's foil becomes more vertical reducing upwards lift essentially self leveling the boat. It looks like there is no analagous structure to an aileron. I don't know if the entire foil itself is adjustable/repositionable so as to be able to change the angle of incidence of the foils.
