A propulsion device of a ship is provided with a port side propeller, a starboard side propeller, a port side propeller axis and a starboard side propeller axis. The port side propeller axis extends backwardly from the hull stern and is connected with the port side propeller. The starboard side propeller axis extends backwardly from the hull stern and is connected with the starboard side propeller. When the propeller diameters of the port side propeller and the starboard side propeller are Dp, the distance between a propeller wing tip of the port side propeller and a propeller wing tip of the starboard side propeller is equal to or more than 0 and equal to or smaller than 0.5 Dp. |
