The objective of the present invention is to provide a ship maneuvering device that can easily maneuver a ship by rotating a propeller at a lower rotational frequency than the rotational frequency of the minimum idling speed of an engine. A control device 4 has a crawling speed navigation mode; a crawling speed navigation mode button 28 that selects whether or not to execute the crawling speed navigation mode is connected to the control device 4; when the execution of the crawling speed navigation mode is selected, when the amount of operation of a joystick lever 20 is at or beneath a baseline amount of operation Ms, the control device 4 causes the rotational frequency N of the engine to be the rotational frequency Nlow of the minimum idling speed, and in accordance with the amount of operation of the joystick lever 20, varies the duty ratio D, which is the fraction of time T1 that a main clutch 23 is engaged in a predetermined cycle T, within a range of no greater than 100%.
