PROBLEM TO BE SOLVED: To provide a frictional resistance reduced ship capable of effectively reducing an energy consumption during cruising by reducing a frictional resistance with less energy consumption. SOLUTION: This frictional resistance reduced ship comprises a negative pressure forming body 20 disposed so that at least a part thereof is projected from the dipped surface 12 of a hull 10 so as to form a negative pressure position 41 lower in pressure than an air space under water, an outlet 25 provided in the negative pressure forming body 20 to discharge air bubbles 42 into the negative pressure position 41 under water, a fluid passage 30 having one end opened to the air space to lead air from the air space to underwater and the other end opened to the underwater through the outlet 25 and a position adjusting mechanism 22 movably supporting the negative pressure forming body 20 in a specified direction and adjusting the projected height of the negative pressure forming body 20 from the dipped water surface 12 of the hull 10.
