Abstract: A motorized hydrofoil watercraft using auto-balancing technology to dynamically balance the watercraft using acceleration in response to pitch changes, and to automatically maintain the watercraft at a desired elevation. The speed of the watercraft can be controlled by shifting of the rider's weight, or by fore-aft translation of the hydrofoil relative to the hull.
