Foil Board

Abstract

A foil board with two hydrofoils is described. A first version has a single mast supporting both a leading hydrofoil wing and a trailing stabilizer wing connected to each other with a fuselage. A second version has two masts, with a front mast supporting a stabilizer wing and a rear mast that supports a hydrofoil, or with the front mast supporting the hydrofoil and the rear mast supporting the stabilizer wing. Both versions have a removable propulsion unit, which allows the user to easily remove the propulsion unit for cleaning, maintenance, repair, or even to remove it temporarily so that the foil board can be used for non-motorized applications.
