MARINE PROPELLER

Ducted Propeller

A ducted propeller, also known as a Kort nozzle, is a propeller fitted with a non-rotating nozzle. It is used to improve the efficiency of the propeller and is especially used on heavily loaded propellers or propellers with limited diameter. The Kort nozzle is a shrouded propeller assembly for marine propulsion. The hydrodynamic design of the shroud, which is shaped like a foil, offers advantages for certain conditions over bare propellers. The ducted propeller is made of copper and approved by CCS, BV, DNV, KR, NK, GL, ABS, etc. It is suitable for container ships, tankers, tug boats, trawlers, fishing boats and yachts, etc. Any question about our products, please be free to contact us, we will reply you as soon as possible.
