A duct (65) for water flow is formed through the interior of the annular nozzle (60). The propeller (50) pulls the vessel in a driving direction (S1). The vanes (71, 72) are positioned after the propeller (50) in the driving direction (S1) of the vessel, whereby the vanes (71, 72) are optimized for redirecting rotational flow components of the flow produced by the propeller (50) into axial thrust.
