摘要

Fin drive and active steering system for a watercraft with two vertically extending fins (21) of elastic material, behind the stern of the watercraft on both sides of the central longitudinal axis of the vehicle are arranged at a distance from one another, and to operate independently of one another according to need for drive - or steering purposes can be used, wherein the fins (21) in each case at one end of a fins arm (14) are mounted, whose other end about a vertical axis (16) at the rear of the watercraft is pivotably mounted and the flossenarm (14) with a 90 degrees to the latter to the central longitudinal axis directed lever arm (15) is fixedly connected, at the free end of a train - and the connecting rod (8, 13) is articulated, and with a driver''s seat (12), from which the fins (21) are operable,characterized by the,in the direction of travel of the watercraft that a front a two-sided lever (5) is provided, of the centrally around a vertical axis (4) is rotatable and on the one end region of the a train - and the connecting rod (8) is articulated, wherein the lever (5) at its ends, foot rests (6) for the transmission of the muscular power of the legs on which a fin (21), one behind the front lever (5) further, which is mounted so as to be increased rear a two-sided lever (11) is arranged, the centrally around a vertical axis (4 '') is rotatable and on the one end region of the other tension - and the connecting rod (13) is articulated, wherein the lever (11) at its ends, handles (10) for the transmission of the muscular power of the arms on the other fin (21) comprises,the driver''s seat (12) is arranged in such a way that leaves it with a view in the direction of travel the foot rests (6) and handles (10) of a convenient and can be operated while sitting position anda tensioning device (7, 18, 19) for regulating the angle of incidence of the fins (21) by means of spring - or rubber voltage from the driver''s seat (12) is provided for.
