<p>A device is described for propulsion, stabilisation and steering of a vessel (12), comprising an elongated first power transmission rod (20) which is rotatable fastened to the vessel and which extends down into the surrounding water, an elongated second power transmission rod (22) connected to an upper end of the first power transmission rod (20), and at least two oar blades (26a, 26b) that can pivot outwards and are arranged to the lower part (20a) of the first power transmission rod (20). The first power transmission rod (20) is arranged to be rotated and pivoted outwards about its point of anchorage to the vessel (12), about both a vertical axis and a horizontal axis, and that the oar blades (26a, 26b) are fastened, at the lower part (20a) of the first power transmission rod (20), as the side surfaces of the oar blades (26a, 26b) extend in a plane that corresponds to the longitudinal axis of said power transmission rod (20).</p> |
