1. A steering control system for a marine vessel, the steering control system comprising:
a controller configured or programmed to perform a control to turn the marine vessel so as to change a target orientation in an automatic marine vessel maneuvering mode that holds a course in which the marine vessel is moved; and
an operator to receive a predetermined operation to cause the controller to turn the marine vessel; wherein
the operator includes a joystick that is able to be rotatably operated and tiltably operated;
the controller is configured or programmed to perform a control to increase a turning amount of the marine vessel according to an operation duration time in which a predetermined operation state of the joystick continues;
the controller is further configured or programmed to perform a control to offset the course of the marine vessel to a left side or a right side by a predetermined distance while continuing movement of the marine vessel based on a leftward tilting operation or a rightward tilting operation on the joystick in the automatic marine vessel maneuvering mode; and
the controller is configured or programmed to move the course of the marine vessel the predetermined distance to the left or the right for each tilting operation of the joystick.
