Abstract
A vessel includes a first propulsion mechanism, at least one second propulsion mechanism, and a hull. The first propulsion mechanism is arranged to generate thrust by an internal combustion engine. The second propulsion mechanism is arranged to generate thrust by an electric motor. The first propulsion mechanism and the second propulsion mechanism are disposed in the hull. The first propulsion mechanism and the second propulsion mechanism are mutually independent. A direction of the thrust generated by the first propulsion mechanism and a direction of the thrust generated by the at least one second propulsion mechanism are the same as each other.
