Abstract The present invention relates to a propeller device for a vessel. The propeller device comprises two propellers arranged to rotate on a common rotating shaft in opposite directions. The driving power is brought to the essentially horizontal shafts of the propellers by a vertical shaft and an angle gear . The propeller device is equipped with at least one annular propeller nozzle in such a way that at least one of the propellers of the pro- peller device is arranged to rotate within said propeller nozzle. In a favourable embodiment of the invention the first propeller , the front propeller, is arranged to rotate within the propeller nozzle and the second propeller is arranged as an open propeller. The propeller device is also favourably so arranged as to be turned around the vertical-shaft for steering the vessel.
