As well as the previously described propeller types, SPW also manufactures propellers for free-fall lifeboats in the commerical shipping sector. There are three major manufacturers of this type of special ...
... using a steerable nozzle no rudder is required Up to 30% efficiency increases Improved steering characteristics Fuel savings Less noise and vibrations Smaller propeller diameter possible Less draft Protection ...
Today, Masson-Marine are able to provide nozzles fitting their range of both fixed pitch and controllable pitch propellers. Using a nozzle can increase the propeller ...
... thrust at low speeds is important for you, then a nozzle is the best solution. The lifting action of the nozzle profile tends to pull the nozzle forward. How does this work? On rudder ...
Advantages of the Becker Nozzle: Increased bollard pull Increased thrust Better propulsion efficiency Better steerage capacity Reduced vibrations Protection of propeller from damage Reduced operational ...

Suitable for all prime movers Our wide range of reduction rations allows the ACG system to be connected to: low, medium and high speed diesel engines electric motors
... condition. Ducted propellers and nozzles can be designed and analysed using specific in-house lifting surface programs and CFD to assure highest efficiency of the entire system. MANUFACTURING Impellers ...
The nozzles are designed and delivered to fit the actual vessel where it shall be fitted. The nozzle kan be delivered either fixed or steerable. They are normally produced in steel with a stainless steel ...
Main advantage of the nozzle is that it increases the thrust of the propeller. A propeller in nozzle provides approximately 25% of total thrust more than a propeller ...
A propeller nozzle is a cylinder surrounding the propeller. It accelerates water flow, increasing propeller efficiency.
ApplicationsSuch devices increase propeller output by providing additional thrust.
TechnologiesThese nozzles increase the velocity of the water flowing over the propeller and reduce disturbance at the tips of the blades. The higher water speed creates a pressure difference, increasing thrust.
How to chooseNozzle and propeller should be chosen together. Criteria include engine power, propeller diameter and related factors.
- Increased output
- Creates drag at higher speeds
