A marine vessel includes a hull including a cabin, an imager that images a field-of-view shielded region, which is a region in which a marine vessel operator's field of view is obstructed when the marine vessel operator located on an operation seat provided inside the cabin looks around an outside of the marine vessel in a horizontal direction, and a display provided at a position visible from the operation seat and that displays a field-of-view complement image, which is an image of the field-of-view shielded region captured by the imager.
