A ship includes a ship's hull which is intended for accommodating cargo and/or people, and at least one rotatable steering propeller as a propulsion unit. The rotatable steering propeller is arranged in a connection unit in the form of a box in the stem of the ship's hull. Electrical and mechanical components for supplying power to and controlling the steering propeller and its electric motor are at least partially combined in functional modules which are in the form of a transport container. The container is designed such that it can be functionally tested, can be accepted at its point of manufacture, and can be installed in this form at any desired location in the ship based upon the container base structure.
