Abstract
A marine vessel includes a hull, left and right propulsion devices attached to a stern of the hull, left and right drive units to change a rotation angle of the left and right propulsion devices about left and right tilt shafts, and to set an angle at which a position of a lower portion of the left and right propulsion devices becomes highest as a maximum rotation angle, left and right lift mechanisms to change a vertical position of the left and right propulsion devices with respect to the hull, and a controller configured or programmed to function as a judging unit to judge whether or not a displacement in a roll direction of the hull has occurred, and a control unit to control the left and right drive units and the left and right lift mechanisms.
