ABSTRACT:
A breakwater system comprising a generally plate-like structure disposed offshore and having an upper face which defines a raised sea floor above the natural bottom. Incoming waves are crested offshore over the breakwater where there is little or no damage caused by the cresting and subsequently formed waves are smaller because of the reduced water depth afforded by the false sea floor of the breakwater. Open spaces are provided in the upper face of the breakwater so that water pressure on the breakwater is equalized thereby minimizing the structural requirements of the breakwater. A plurality of false sea floors, each disposed at a different distance from the natural bottom may be utilized in forming the breakwater system of the invention. Because the breakwater is raised off the bottom there is no interference with the normal tidal and other near shore currents.
