The invention relates to a device for reducing the driving power requirement of a watercraft, comprising a flow guiding surface from which at least one first fin projects. A first end of said first fin is fixed to the flow guiding surface, and a second end of the first fin is embodied as a free end.

Device for improving the water influx towards a propeller of a watercraft

A drive system for a watercraft has a water inlet opening, a water outlet opening, and a fin system. A propellerless pre-nozzle for the drive system is configured rotationally asymmetrically in order to further improve the drive efficiency.

Pre-nozzle for a drive system of a watercraft to improve the energy efficiency

A device is provided for reducing the drive power requirement of a watercraft includes a fore-nozzle, wherein at least one outer fin projects outwards from the fore-nozzle.

Device for reducing the drive power requirements of a watercraft

A device for reducing the drive power requirement of a ship and even for not very quick ships of all types, in particular for slow, wide ships, such as tankers, bulkers and tugboats, and for improving the propeller blower stream as well as for producing a pretwist includes a front nozzle fixedly installed on the hull with fins or hydrofoils placed in the inner space thereof.

Device for reducing the drive power requirement of a ship

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&#xb0;, on a horizontal transverse axis that extends through the centre of the fore-nozzle.
