A buoyant wave energy device is disclosed that incorporates an open-bottomed tube (1304) of substantial length in which is partially enclosed a first body of water that oscillates in response to wave action. The device incorporates a buoy (1302) to which an upper end of the tube is connected and inside of which is trapped a second body of water (1329) of substantial mass. A differential phase in the oscillations of the water trapped in the tube, and the oscillations of the buoy of augmented mass, result in the periodic compression of a pocket of air (1325) trapped at the top of the tube. The pressurised air passes through valve (1327) into an accumulator (1326) partially formed by the body of water (1329) within the upper part of the buoy (1302) and the subsequent expulsion of pressurized air through a turbine (1322) in a duct (1308) thereby generates electrical power. A second valve (1331) allows for the return of air to the top of the column as the pressure of the pocket of air is periodically reduced.
