Document Type and Number:
WIPO Patent Application WO/2014/009683
Kind Code:
A3
Abstract:
A water-borne vessel for propulsion by incident waves is provided, the vessel comprising a hull, the hull of the vessel comprising an elongate bow portion having a length greater than its width at its widest point; an elongate stern portion having a length greater than its width at its widest point; and a central portion between the bow portion and a stern portion, the central portion having a width greater than the widths of the bow and stern portions, the central portion comprising a first flared region at the junction with the bow portion, the first flared portion having a width greater than the width of the adjacent region of the bow portion, and a second flared region at the junction with the stern portion, the second flared region having a width greater than the width of the adjacent region of the stern portion, the central portion having its widest point between the first and second flared regions and greater than the widths of the first and second flared regions; wherein the bow and stern portions act to cut through an incident wave; and wherein the central portion acts to induce the hull to pitch and roll under the action of an incident wave; the vessel further comprising a foil assembly for generating movement of the vessel through the water under the action of an incident wave. A foil assembly for a wave-powered, water-borne craft is also provided, the foil assembly comprising a substantially rigid leading edge assembly having a first end and a second end; a flexible foil extending from the leading edge assembly, the flexible foil having an inner edge and a trailing edge; and a tensioning assembly for tensioning the flexible foil, the tensioning assembly applying a tension to the flexible foil in the direction away from the leading edge assembly and towards the trailing edge of the flexible foil, the tension be provided to the flexible foil at an angle between the inner edge and the trailing edge of the flexible foil.
