ABSTRACT:
A machine for making waves on the free surface of a body of liquid comprises a member which is buoyant in the liquid, driving means mounted on and supported above the free surface of the water by the buoyant member to cause a periodic motion thereof relative to the surface of the liquid between a raised position and a lowered position, such relative motion causing substantial variations in the liquid displacement of the buoyant member, said buoyant member comprises a longitudinally elongated wave making plunger, floatation means underlying said wave making plunger for supporting said wave making plunger with its longitudinal extent horizontally disposed at a level with respect to the free surface of the water when in use such that the plunger displacement is substantially zero when in said raised position.
