ABSTRACT:
Apparatus for dynamic support and height control of a boat equipped for power or wind propulsion and adapted to be supported above the water by hydrofoils, including a control hydrofoil and a main hydrofoil pivotally mounted on the boat, the apparatus being constructed and arranged to enable the control hydrofoil to regulate the main hydrofoil's angle of attack. The innovation being that the control hydrofoil is structurally placed in a completely submerged position where it utilizes its load variation dependency upon depth of submergence to automatically seek and maintain the boat at a predetermined height range above the water surface.
