Disclosed is a wave energy conversion device (1) , for use in relatively shallow water, which has a base portion (2) for anchoring to the bed of a body of water and an upstanding flap portion (8) pivotally connected (12) to the base portion. The flap portion is biased to the vertical and oscillates, backwards and forwards about the vertical in response to wave motion acting on its faces. Power extraction means extract energy from the movement of the flap portion. When the base portion is anchored to the bed of a body of water with the flap portion facing the wave motion, the base portion and the flap portion extend vertically through at least the entire depth of the water, to present a substantially continuous surface to the wave motion throughout the full depth of water from the wave crest to the sea bed. The flap portion is sufficiently buoyant in the water so as to be biased to the vertical in use. The flap portion has a high centre of buoyancy and a low centre of mass.
