Marine vessel maneuvering supporting apparatus and marine vessel including the same

A marine vessel comprising:

• a hull;
• a propulsion system and a steering mechanism attached to the hull;
• and
• a marine vessel maneuvering supporting apparatus that is arranged to determine target values for the propulsion system and the steering mechanism;
• the marine vessel maneuvering supporting apparatus including:
• a first operational unit arranged to select a forward drive position for forward drive of the propulsion system, a reverse drive position for reverse drive of the propulsion system, and a neutral position for an inactive state of the propulsion system;
• a second operational unit arranged to command rightward and leftward movement of the marine vessel;
• and
• a target value computing unit arranged to determine target value including a target propulsive force for the propulsion system and a target steering angle for the steering mechanism, such that the marine vessel undergoes parallel or substantially parallel movement in a direction that is in accordance with an operation position of the first operational unit when rightward or leftward movement is commanded by the second operational unit.
