ABSTRACT:
A watercraft capable of operating in hydrofoil mode or ground-effect mode with self-righting retractable V-shaped foil, fiberoptic control systems, and a plurality of aircraft style engines with variable pitch propellers for speed and direction control. The V-shaped foil can be fully retracted into the hull allowing operation in shallow water, and the ability to execute a beach landing. Propeller pitch can be reversed allowing the craft to backup. Each engine and propeller can be controlled individually allowing rotating in-place for precise maneuvering control. The hull is a flying wing, airfoil shape for efficient high-speed operation. Engine nacelles are located on airfoil shaped struts, angled in a V-shape, for self-righting effect at high speed. Fuel tanks are within the nacelles, thus outside the main hull for safety.
