Watercraft running system, and watercraft including the same

A watercraft running system comprising:

• a propulsion device to apply a propulsive force to a hull of a watercraft;
• a steering device to change a course of the watercraft;
• a course changing operator operable by a user to change the course of the watercraft;
• a port-side attitude control plate and a starboard-side attitude control plate provided on a port side and a starboard side, respectively, of the hull to control an attitude of the hull and to move up and down on the port side and the starboard side, respectively, of the hull;
• a port-side actuator and a starboard-side actuator to actuate the port-side attitude control plate and the starboard-side attitude control plate, respectively;
• and
• a controller configured or programmed to include a first control mode in which the steering device is controlled according to the operation of the course changing operator, and a second control mode in which the port-side actuator and the starboard-side actuator are controlled according to the operation of the course changing operator;
• wherein
• the controller is configured or programmed to determine whether or not a steering position of the steering device is a neutral position, to prohibit shifting from the first control mode to the second control mode if the steering position is not the neutral position, and to permit the shift from the first control mode to the second control mode if the steering position is the neutral position.
