Abstract

A device for converting wave motion into energy has one or more pontoons (10, 12) that are located at right angles to the wave propagation. The pontoons are spaced apart in substancially paralled relationship and one or more floating members (20) span the distance between the pontoons. The pontoons have pairs of articulated arms connected to the extremities of the floating members and that rise and fall with the motion of the waves relative to the rise and fall of the pontoons. The extremities of the arms are connected to energy converters located inside the pontoons.
