A steering device having two rudder plates vertically suspended at a distance from an outer edge of a propeller. The rudder plates are biaxially arranged and symmetrically rotate around a screw shaft within a propeller radius from a screw shaft center, on a propeller rotation plane, and are turned from aside the propeller to downstream of the propeller by rotation of the steering shafts, each of which is driven independently by two hydraulic driving mechanisms. The steering action of the steering device has two modes: the two-independent mode, where the plates rotate in the same direction, and the two-same direction modes, where the plates move in different directions. A method for steering the same to enhance a thrust flow by increase in a propeller rate is also provided.
