Abstract:
1. 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 ( wherein at least one of the hull elements ( wherein energy for operating the movement devices ( the sinusoidal pattern of movement is created by means of angular changes between the hull elements ( that the row of hull elements ( the row comprises at least 4 hull elements ( 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 (
