a combination floating breakwater and wave energy collecting system in which a pair of joint floating spread wings are provided between which a vessel can be moored . the spread angle of the wings is adjustable and the wings can be jointly swung about their juncture so as to extend from the juncture generally in the direction of wave and wind travel so that the vee - shaped area between the wings is on the lee side . the wings have rows of improved wave energy collecting cells used to drive air turbines coupled to electric generators without intermediate compressed air storage and this energy conversion assists in dampening the wave action in the moorage zone between the wings .
