Patent ID: 8287323

Claim:
A wave-powered water vehicle which comprises a float which (A) when it is floating in still water, has a horizontal length and a horizontal breadth, the breadth being at most 0.3 times the length, (B) comprises (i) a satellite-referenced position sensor, (ii) communications equipment for receiving signals, and (iv) communications equipment for sending signals, and (C) does not include any component for propelling the float forward, a swimmer, and a tether connecting the float and the swimmer, the float, swimmer and tether being such that, when the vehicle is in still water, (i) the float is on or near the surface of the water, (ii) the swimmer is submerged below the float, and (iii) the tether is under tension; the swimmer, when the vehicle is in wave-bearing water, interacting with the water to generate forces which move the float horizontally.
