Claim:
A non-powered wave riding watercraft adapted to support a surfer above a surface of water, the craft being controlled solely by the surfer in a prone or kneeling position, said craft being propelled solely by the efforts of the rider and by the force of gravity acting in conjunction with the sloping forward face of a progressive gravity wave, said craft comprising: a low buoyancy hull, the hull having forward and rear ends and a longitudinal axis extending between the forward and rear ends; a forward strut assembly mounted at substantially the forward end of the hull, the forward strut assembly comprising at least two forward struts positioned about the longitudinal axis of the hull and extending generally downwardly from a bottom of the hull; at least one rear strut extending generally downwardly from the bottom of the hull; a canard hydrofoil attached to the forward strut assembly and oriented transversely to the longitudinal axis of the hull, the canard hydrofoil having at least right-side and left-side foil segments; a main hydrofoil attached to said at least one rear strut, the main hydrofoil extending transversely to the longitudinal axis of the hull and positioned below the bottom of the hull; wherein the main hydrofoil is adapted to be submerged below the water surface and end segments of the canard foil are adapted to pierce the water surface when the craft is traversing across the face of a wave.
