Abstract
A Ship Propulsion Arrangement A ship propulsion arrangement is provided in which a mechanical drive shaft (3) extends through a hull (9) of a ship (1) to an external body (7). The external body incorporates an electric motor. The mechanical drive shaft (3) is driven when required by either a prime mover (2) located within the ship (1) or by the electric motor in the external body (7). This arrangement provides the benefits of hybrid operation without necessary accommodation of the electric motors within the limited hull space available in a ship (1).
