A device for absorbing the energy that is carried in waves on the surface of the sea formed of a beam 4 positioned across the top of a buoyant body 1 and supported at one end by a pivot 3 and at the other end by a power converter 6 and spring 5. The device is moored to the sea bed by a cable 7 from one end of the beam. On the opposite side to the mooring cable a weight 2 is attached, either to the beam or to a cantilever (8, Figs 3, 4) connected to the buoyant member. A series of waves passing the device will cause the buoyant body to rise and fall, thereby extending and compressing the power converter and absorbing power from the waves. In a further arrangement (Fig 5) the mooring line is extended so that the device sits at an angle to the mean level of the surface of the sea.
