The invention provides a device which can reduce the drag and assist the steering of the ship, mainly to set up a 3-way pipe in the bow where is below the water level. The 3-way pipe leads to three openings at the stem, the port side and the starboard side respectively. At least one control valve (or deflector) can be provided in the 3-way piping system. The valve (or deflector) can be controlled from the bridge, with a diversion device. When the ship sails forward, water flows into the 3-way pipe from the forward pipe, distributed to both side pipes and then outflow, so that it can reduce the pressure drag to the stem, improve the ship's speed and save bunker. When the valve (or deflector) is set as neutral, the water will be distributed evenly to both side pipes, which will not affect the ship's heading. When the valve (or deflector) deflects more water to either side's pipe, the ship will turn to the opposite side.
A device for reducing the sailing drag and assisting the steering of the ship is provided with a 3-way piping system in the bow below water level, of which is in the form of “inverted Y-shape” structure leads to the opening at stem and both sides of the hull, the axis of each opening at side of hull being normal to the long axis of the ship, at least one valve is equipped in the 3-way piping system, which can control the flow direction;
