A device for reducing the power demand for the propulsion of a ship, and for broad-built or non-broad-built not-very-fast ships of any type which is affixed to the hull at a short distance upstream of the propeller, comprises a fore-nozzle with fins or hydrofoils that are arranged within the fore-nozzle, wherein the fore-nozzle, at the top, can be tilted forwards by up to 8°, on a horizontal transverse axis that extends through the centre of the fore-nozzle. |
