Abstract

In order to provide a flow guide surface for the stern of a single or multi-propeller ship, a guide surface nozzle 1 is provided in front of the propeller 5 at a horizontal spacing of up to one propeller diameter. The centroid of the enclosed cross- sectional area lies above the propeller axis 7. The nozzle may comprise two half shells which may have different axial directions or may be formed as brackets fixed to the hull of the ship. <IMAGE>
