Abstract

A wave energy conversion device (1), for use in relatively shallow water, includes a base portion (2) for anchoring to the bed of a body of water. A flap portion (6) is pivotally connected to the base portion (2) and is biased to the vertical. The flap portion (6) oscillates backwards and forwards about the vertical in response to wave motion. The flap portion (6) includes an upper portion (8) upstanding above the pivot axis (7) for extracting energy from the wave motion and a lower portion (10) that has a biasing mass located below the pivot axis. The biasing mass provides a restoring force acting to bias the flap to the vertical when the flap portion (6) oscillates. Power extraction means is provided for extracting energy from the movement of the flap portion.
