A combined rudder and propeller device for propelling, steering and manoeuvring a ship or other vessel. The device comprises a rudder 1, which is rotatable in relation to the vessel about a vertical axis of rotation. A propeller unit 2 is built together with the rudder 1, the said propeller unit comprising a propeller 6, which is fitted on a horizontal propeller shaft, which is mounted for rotation in a propeller unit housing 9. The unit is also mounted for rotation in relation to the ship about a vertical axis. The axes of rotation of the rudder 1 and the propeller unit 6 coincide, so that the rudder and the unit can be rotated in relation to one another. The rudder 1 can be connected to a steering machine 11, 13, 14 for rotation of the rudder, whilst the propeller unit 2 can be selectively locked either to the ship in a fixed position or to the rudder for rotation together therewith.
