ABSTRACT:
An elongated floating device connected via flexible means to the bottom of the water in such a manner that the floating device can undergo displacements through the action of wave forces while a structure is provided for redressing such displacements. At least one heavy plate extends in a vertical plane transversely to the length of the floating device, and is situated at a level below water level at least as low as the bottom of the floating device, and is suspended from the floating device so as to be freely pivotable about a horizontal axis which extends transversely to the length of the floating device. The plate has flat vertical opposite surfaces that are unconfined and are freely exposed in all horizontal directions to the ambient water.
