Abstract: A ship is disclosed which can include a hull, at least one propulsion unit having a propulsion engine, transmission, at least one propeller connected via the transmission to the propulsion engine, and an oscillation sensor situated in a vicinity of the at least one propeller in order to sense cavitation of the at least one propeller. A control unit can control the propulsion engine, the oscillation sensor being connected to the control unit, whereby the output signal of the oscillation sensor is analyzed in the control unit to detect and indicate that a worse degree cavitation is emerging on a display unit at the navigation bridge and/or regulate the rotation speed and/or the power of the propulsion engine.

Abstract: A support strut has an upper end rotatable supported at a bottom of a vessel and a lower end supporting a casing. A first electric motor within the casing drives a propeller via a first shaft. An annular nozzle surrounds an outer perimeter of the propeller and is fixedly supported on the casing, with a support construction comprising at least three vanes extending in the radial direction between the outer perimeter of the casing and the inner perimeter of the nozzle. A duct for water flow is formed through the interior of the annular nozzle. The propeller pulls the vessel in a driving direction. The vanes are positioned after the propeller in the driving direction of the vessel, whereby the vanes are optimized for redirecting rotational flow components of the flow produced by the propeller into axial thrust.
