Abstract
A watercraft propulsion system includes a propulsion unit to apply a propulsive force to a hull, and a controller configured or programmed to control the propulsion unit in response to a lateral movement command to cause the hull to move in a zig-zag pattern in a direction indicated by the lateral movement command between two parallel reference lines extending laterally of the hull and spaced apart from each other anteroposteriorly of the hull while maintaining an azimuth of the hull. The propulsion unit may include a bow thruster at the bow of the hull to generate a propulsive force laterally of the hull, a propulsion device on the hull to generate a propulsive force anteroposteriorly of the hull, and a steering to change the course of the hull.

A watercraft propulsion system comprising:
- a bow thruster at a bow of a hull to generate a propulsive force laterally of the hull;
- a propulsion device on the hull to generate a propulsive force anteroposteriorly of the hull;
- a steering to change a course of the hull;
- and
- a controller configured or programmed, in response to a lateral movement command, to set two parallel reference lines extending laterally of the hull and spaced a distance apart from each other anteroposteriorly of the hull, and to control the bow thruster, the propulsion device, and the steering to cause the hull to move in a zig-zag pattern in a direction indicated by the lateral movement command between the two reference lines while maintaining an azimuth of the hull.
