Abstract

A training hydrofoil system for connection with a watercraft comprises a first wing including at least one adjustable surface and a second wing including at least one adjustable portion. The system further includes a fuselage extending longitudinally and the first and second wing connected to the fuselage and extending latitudinally relative to the fuselage, the fuselage including an attachment feature for attaching to the watercraft. The system further includes an electronic control unit capable of actuating at least one of the adjustable surface and adjustable portion to modify a course of the watercraft, and a power source. Both the power source and the electronic control unit are positioned in the fuselage.

IPC Classes  ?

• B63B 1/28 - Hydrodynamic or hydrostatic features of hulls or of hydrofoils deriving additional lift from hydrodynamic forces of hydrofoil type with movable hydrofoils

Abstract

A personal watercraft comprising a body having a seat and a hull, the seat configured to support a user with the body floating in water, a plurality of hydrofoils extending outwards from the body and coupled to a positioning system, the plurality of hydrofoils being configured, in combination, to raise the hull of the personal watercraft above a waterline in the water when the personal watercraft is in use and under the influence of a propulsion force, one or more sensors that provide sensor data of the watercraft during use, a computer-readable medium having a processor and a memory having instructions that, when executed by the processor read the sensor data, and based on the read sensor data, send a signal to the positioning system to adjust the position for at least one of the plurality of hydrofoils.

Abstract

A passively stable personal hydrofoil watercraft that has a flotation device, wherein a user can ride in a prone, kneeling, or standing position. The watercraft includes a strut having an upper end interconnected with the flotation device and lower end connected with a hydrofoil. The hydrofoil greatly reduces the power required to travel at higher speed. The watercraft also includes a propulsion system connected to the hydrofoil. Both longitudinal and directional control of the watercraft is via weight shift, eliminating the need of any movable surfaces. The flotation device, strut, and hydrofoil may be permanently interconnected or may be detachable.
