System for controlling watercraft, method of controlling watercraft, and watercraft

Abstract

A watercraft operating system includes a marine propulsion device and a watercraft operating controller. In a compass direction keeping control to keep a watercraft oriented in a target compass direction, the watercraft operating controller is configured or programmed to turn a propeller between a first steering position and a second steering position at a predetermined time interval. The first steering position is where the thrust is applied to the watercraft in a back-and-forth direction and a right-and-left direction. The second steering position is obtained by reversing the first steering position in either the back-and-forth direction or the right-and-left direction. The watercraft operating controller is configured or programmed to control the magnitude of the thrust and a rotational direction of the propeller such that the watercraft performs bow turning toward the target compass direction when the propeller is located in each of the first and second steering positions.
