According to one embodiment of the present invention, a ship has a friction reducing device on a hull, wherein the friction reducing device includes: a compressor arranged on the hull; a gas spray hole arranged on the hull and spraying gas for reducing frictional resistance between the hull and seawater; a main pipe and an auxiliary pipe connecting the compressor and the gas spray hole; a bypass pipe connected to the compressor; and a control part operating opening and closing of the main pipe, the auxiliary pipe, and the bypass pipe in accordance with a control signal. Therefore, the ship can prevent the seawater from being introduced into the compressor through the gas spray hole of the friction reducing device in advance.
