Abstract
A watercraft operating system includes a marine propulsion device and a watercraft operating controller configured or programmed to execute a position keeping control to control the marine propulsion device such that a watercraft is kept at a target spot. The position keeping control includes a first bow turning control to control an output of the marine propulsion device, a rotational direction of a propeller, and a rudder angle to be within a predetermined angular range based on information regarding the target spot of the watercraft and information regarding a position of the watercraft, and a second bow turning control to control the rotational direction of the propeller and the rudder angle to be a first angle greater than a maximum rudder angle of the predetermined angular range based on the information regarding the target spot of the watercraft and the information regarding the position of the watercraft.
