Marine vessel maneuvering system, and marine vessel

A maneuvering system for a marine vessel, the maneuvering system comprising:

• a propulsion device to propel a hull;
• a steering device to pivot a direction of a propulsive force generated by the propulsion device laterally of the hull;
• a forward/reverse drive switch to switch the direction of the propulsive force generated by the propulsion device between a forward drive direction and a reverse drive direction;
• a steering wheel pivotable about a pivot axis in a predetermined full operation angle range clockwise and counterclockwise by a user of the marine vessel to manipulate the steering device;
• a forward drive operator that is pivotable together with the steering wheel about the pivot axis;
• and
• a controller configured or programmed to control the propulsion device and the forward/reverse drive switch according to operation of the forward drive operator;
• wherein
• the controller is further configured or programmed to:
• perform a forward drive propulsion control when the forward drive operator is operated to switch the direction of the propulsive force generated by the propulsion device to the forward drive direction, and control a magnitude of the propulsive force generated by the propulsion device according to an operation amount of the forward drive operator;
• and
• enable the forward drive propulsion control when the operation angle of the steering wheel falls within a forward drive operation valid range in the full operation angle range, and disable the forward drive propulsion control when the operation angle of the steering wheel falls outside the forward drive operation valid range.
