抵抗軽減型船舶。 The bottom of the bow of a single-shaft ship is equipped with a bubble generator to reduce frictional resistance to generate bubbles to cover the bottom of the ship, and the main bottom concave surface that guides the bubbles generated from the bubble generator toward the bottom of the stern is the center line of the ship. At the same time, a diagonal concave bottom surface is connected to the rear end of the main concave bottom surface to guide the bubbles diagonally rearward to the left and right to avoid the bubbles from flowing into the stern propeller. A friction-reducing ship characterized by:
