The vessel display device includes an information acquirer that acquires the same type of information on a plurality of propulsion machines included in the vessel, a display information generator that generates, based on the information acquired by the information acquirer, display information which displays information on the plurality of propulsion machines on a single scale, and a display that displays the display information generated by the display information generator. The display information generator may generate display information which displays the same type of information on the plurality of propulsion machines in a different format on a single scale. The display information generator may generate display information which sequentially displays the same type of information on the plurality of propulsion machines on a single scale.
