Abstract: A motorized hydrofoil apparatus may include a sailboard having a top surface and a bottom surface; a first hydrofoil assembly having a first hydrofoil and a first support unit; a second hydrofoil assembly having a second hydrofoil and a second support unit; and a propulsion system. The hydrofoil apparatus may also include one or more sensing units disposed on predetermined locations on the first support unit to operatively communicate to a plurality of actuating units on the first hydrofoil assembly and second hydrofoil assembly to automatically generate corrective responses to various destabilizing hydrodynamic effects to stabilize the hydrofoil apparatus.
