Abstract

A wave energy converter (WEC) utilizing one or multiple floats together forming an elongated wave front parallel (EWFP) float rotatably connected by at least one swing or drive arm to a floating or shore or seabed fixed body or frame, such that the swing arm is rotating about a submerged pivot point on such body or frame and constraining the motion of the float(s) relative to the body or frame. Relative to the direction of oncoming wave fronts and relative to the still water line (SWL), the at least one EWFP float is substantially forward of, and above, the pivot point such that the float concurrently moves both upward and rearward on wave crests and returns both forward and downward on ensuing wave troughs. The rear surface of the EWFP float is substantially arcuate and concave with a radius approximating Its distance from the pivot point.
