Abstract
A wave riding surfing board with a pair of transversely oriented hydrofoils, each attached to respective front and rear struts, for supporting a surfer in a prone or kneeling position. In operation, the front canard hydrofoil is arranged for piercing the surface of the water and partially supporting the weight of the rider and the board, while the fully submerged rear hydrofoil is arranged for supporting the remaining 90–100 percent of the weight. The rigging angle of the front canard hydrofoil can be adjusted. The surfing board can be maneuvered by banking the board. In a preferred embodiment, a pair of control handles and a control mechanism give rider a control over the front canard hydrofoil and the flap surfaces on the trailing edge of the rear strut to enable precision maneuvering.
Claims21
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.
