Abstract: The propulsion unit comprises a support frame (20), a nozzle (60) attached to the support frame, a propeller (40) within the nozzle, the propeller having an axis (X-X) of rotation and comprising propeller blades (41-44), and a support construction (50) on either axial side of the propeller, the support construction comprising vanes (51-57) extending inwards in a duct (65) formed by the nozzle. A minimum axial distance (A5) between the blades of the propeller and the vanes of the support construction is in the range of 0.5 to 10% of a diameter of the propeller.

Abstract: The vessel comprises a hull (20) having a bottom line (BL) and a bow (30). A recess (100) is arranged in the bow above the bottom line of the hull of the vessel, the recess comprising a bottom surface (110) forming a portion of the hull of the vessel. At least one thruster (60, 70) being rotatable around a vertical axis (Y1, Y2) is positioned within the recess so that a propeller (63, 73) of the thruster in a first position, is positioned below the bottom surface of the recess and in a second position, is positioned above the bottom surface of the recess.
