Abstract
A watercraft propulsion system includes first and second propulsion devices attachable to a hull asymmetrically with respect to an anteroposterior center line of the hull, a lateral movement command generator to generate a first lateral movement command and a second lateral movement command to laterally move the hull rightward and leftward, and a controller. The controller includes a memory to store first and second lateral movement thrust ratios indicating ratios between a forward propulsive force and a reverse propulsive force in a first lateral movement control and a second lateral movement control. When one of the first and second lateral movement thrust ratios is set in a calibration mode, the controller is configured or programmed to set an initial value of the other of the first and second lateral movement thrust ratios to an inverse of the one of the first and second lateral movement thrust ratios.
