1. A marine vessel maneuvering system comprising:
a propulsive force generator to generate a propulsive force to propel a marine vessel;
a steering mechanism to steer the propulsive force generator; and
a controller configured or programmed to control the propulsive force of the propulsive force generator and steering by the steering mechanism based on a user's operation on an operator to maneuver the marine vessel; wherein
the controller is configured or programmed to control a steering speed to be a first steering speed when the operator is moved from a neutral position, and to control the steering speed to be a second steering speed that is lower than the first steering speed when the operator is returned to the neutral position and the propulsive force of the propulsive force generator is stopped or not completely stopped.
