The invention relates to the extraction of energy from waves and comprises a linear array of several Salter's Ducks set roughly perpendicular to the oncoming wave crest. The Ducks are each rotatably connected through a power take-off device to a rigid space frame. The Ducks are spaced and designed to have an optimized natural frequency of each Duck and the array and space frame as a whole and the response characteristics of each Duck may be further modified by controls on the power take-off in response to signals from the whole array of Ducks, particular the lead Duck, but possibly also each other Duck and the space frame motion as a whole. The whole space frame and Duck array can be moored by any means appropriate, but most likely to a single point catenary moor, though other mooring systems are possible.
An apparatus for converting the energy of waves in water to other useful forms comprising a multiplicity of floating ovoid bodies with a center of rotation horizontal and approximately perpendicular to an oncoming wave, said bodies being configured with an asymmetric shape about said axis of rotation so as to cause said cams to rotate about said axes of rotation when excited by said wave, said cams being arrayed in columns approximately perpendicular to the direction of travel of the wave, said bodies being rotably attached to an elongated rigid structure that fixes said bodies in position relative to each other, said rotable attachment being equipped with means to convert the rotation of said bodies to other forms of energy, and said elongated structure floating horizontally near the surface of the water, supported by said bodies.
