Patent ID: 6923693

Claim:
A system for utilisation of a sinusoidal pattern of movement for propulsion comprising a plurality of rigid hull elements ( 1 ), at least partly submerged, arranged in a row, rotatably interconnected for rotation about parallel axes of rotation across the longitudinal direction of the row of hull elements, and movement devices ( 2 ) for rotating substantially the whole row of hull elements relative to one another, wherein the row of hull elements ( 1 ) comprises a vessel ( 3 ), and wherein at least one of the hull elements ( 1 ) comprise a watertight chamber, and wherein energy for operating the movement devices ( 2 ) is provided by an internal energy source, whereby propulsion of the vessel ( 3 ) is achieved completely or partly by induced rotation of the hull elements ( 1 ) relative to one another, and further wherein the sinusoidal pattern of movement is created by means of angular changes between the hull elements ( 1 ) and is in a plane substantially parallel to the surface of the water, and that the row of hull elements ( 1 ) forms a complete sinus wave, and the row comprises at least 4 hull elements ( 1 ) behind one another and that the hull elements have a substantially constant cross sectional area over the length of the row of hull elements, and where the hull elements ( 1 ) have rigid sides with an open space inside, thus forming a shell structure.
