ABSTRACT:
A mobile, buoyant breakwater structure is disclosed having a plurality of wave reflecting surfaces alternatingly offset from each other by a distance approximating one-half the wave length of impinging waves to decrease the motion of the structure and the transmission of wave motion past the structure. An anchoring system is provided which is connected to the breakwater structure and adapted to act substantially through an action center of the structure, the location of which is defined by the intersection of the plane of action of the resultant buoyant force on the structure and the plane of action of the resultant horizontal force on the structure for a selected designed wave.
