Patent ID: 7052205

Claim:
A method for forming an artificial reef for shaping the waves of the sea in which blocks are placed on the sea bed, comprising the steps of: providing a set of at least two blocks, each of the blocks having an internal cavity of sufficient volume to permit the block to float, at least one entry opening with a valve for the passage of air, in an upper region of the block, and at least one opening for the passage of sea water, in a lower region of the block; arranging the set of blocks in an interconnected relationship such that the set of blocks defines a structure in the configuration of an arrowhead, with the valves closed, on a surface of the sea, in suitable positions and arrangements above a location on the sea bed designated for receiving the artificial reef; and opening the valves in the blocks to permit the sea water to enter the blocks in a controlled manner through the openings for the passage of sea water, with the air being expelled through the openings for air, wherein the set of blocks sinks to the sea bed, at the designated location, to form the artificial reef.
