  • Patent number: 7497643
    Abstract: An artificial reef comprises at least one bag which is generally configured to define at least a portion of a reef and which is at least partially fillable with air. An anchor is attached to the bag for maintaining the bag at a desired location substantially underwater. A plurality of such bags may be attached to one another and configured so as to define a reef which enhances the suitability of waves for surfing or which mitigates beach erosion.

  • Patent number: 5833393
    Abstract: A wave forming generator which can repeatedly produce and launch singular waves across the surface of a body of water. The wave generator includes an air compressor interconnected with are a large air pressure holding tank. A hydraulic actuated valve is fitted onto the air pressure tank. Piping is then connected to the valve and ran out and down to join and connect to several main water tubes, cannons, pipes, or anything that can take the form of a long round elongated chamber. The elongated chambers are submerged just under the surface of the water, being anchored on an angle with the opened ends of the water chambers pointing upwardly. The opened ends of the elongated chambers face towards the artificial reef, shoreline, or the opposite end of the pool.
