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.

A high-speed watercraft comprising:
- a hull having an exterior that is substantially the shape of an airfoil, said hull having a front and a rear;
- a pair of struts being located at said rear of said hull, a pair of nacelles being secured to said pair of struts, each one of said pair of nacelles including a rear facing propeller, each of said propellers including variable pitch, said propellers enabling in-place rotation of said watercraft;
- a pair of elevators extending from a rear edge of said hull;
- a fly-by fiber control system for isolation of electrical noise from other control systems in said watercraft;
- and
- a V-shaped hydrofoil wing being mounted to a bottom of said hull, said V-shaped hydrofoil wing having an adjustable center depth and two hydrofoil segments with a cross section having a airfoil cross section, said V-shaped hydrofoil wing being lockable at any extension position, said V-shaped hydrofoil extending substantially a width of said hull.
