Watercraft propulsion system, and watercraft

A watercraft propulsion system comprising:

• a bow thruster provided at a bow of a hull to generate a first propulsive force laterally of the hull;
• a propulsion device provided on the hull to generate a second propulsive force anteroposteriorly of the hull;
• a steering to change a course of the hull;
• a joystick tiltable from a neutral tilt position in all directions, and twistable leftward and rightward from a neutral twist position about an axis of the joystick;
• and
• a controller configured or programmed to control the bow thruster, the propulsion device, and the steering according to an operation of the joystick;
• wherein
• the controller is configured or programmed to cause the bow thruster to generate the first propulsive force according to a lateral component of a tilt amount of the joystick, to cause the propulsion device to generate the second propulsive force according to an anteroposterior component of the tilt amount of the joystick, and to control the steering according to a twist amount of the joystick.
