To provide a large-sized multiple screw ship in which the speed range is increased and the fuel efficiency is improved.

This multiple screw ship includes a first shafting device 50 to which a power is transmitted from a first propulsion engine 20 and a second shafting device 30 to which a power is transmitted from a second propulsion engine 10. The first shafting device 50 includes a first front shaft 51 joined to the first propulsion engine 20, a first rear shaft 52 to which a first propeller 54 is joined, and a first gear device 53 which receives, from the first front shaft 51, the power transmitted from the first propulsion engine 20, and transmits the power to the first rear shaft 52 or disconnects the power.
