Abstract: 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.
