1. A marine vessel comprising:
a marine vessel propulsion control system including:
a display;
at least one memory to store a set of instructions; and
a controller configured or programmed to execute the set of instructions to control movement of the marine vessel, and to execute a fixed point holding control to restrict movement of the marine vessel to keep the marine vessel at a predetermined position; wherein
when a target position is newly set during execution of the fixed point holding control, the controller is configured or programmed to execute a control to move the marine vessel to the target position;
the display is operable to display a remaining distance from the marine vessel to the target position as the marine vessel is moving to the target position;
the controller is configured or programmed to change, according to a movement state of the marine vessel to the target position, a thrust level to be generated by a propulsion device of the marine vessel during execution of the fixed point holding control;
when the marine vessel is moving to the target position, the display displays a deviation of a current bow direction of the marine vessel with respect to a bow direction of the marine vessel at a time point when the target position is set; and
the fixed point holding control causes the marine vessel to stay at the predetermined position, or causes the marine vessel to stay at the predetermined position and maintain a bow direction of the marine vessel in a predetermined direction.
