Abstract

The present watercraft operating system (100) includes a marine propulsion device (3) and a watercraft operating controller (30). Under a compass direction keeping control for keeping a watercraft (10) oriented in a target compass direction, the watercraft operating controller (30) turns a propeller (14) between a first steering position and a second steering position at a predetermined time interval. The first steering position is a position where the thrust is applied to the watercraft (10) 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 (30) controls the magnitude of the thrust and a rotational direction of the propeller (14) such that the watercraft (10) performs bow turning toward the target compass direction when the propeller is located in each of the first and second steering positions. The watercraft operating controller (30) controls the rotational direction of the propeller (14) such that a direction of the thrust in the back-and-forth direction generated at the first steering position and a direction of the thrust in the back-and-forth direction generated at the second steering position are opposite when the watercraft (10) is caused to perform bow turning in the same direction at the first steering position and the second steering position.
