Feathering Controllable pitch propellers
Controllable pitch propellers (CPP) for sailing vessels, or other vessels that need feathering have the same properties as a conventional controllable pitch propeller, but in addition they are designed to have fully feathering mode, but be aware that they have limited reverse. For smaller propeller they are not delivered with reverse at all and then a gearbox with reverse must be used. For the bigger propellers it is optional if a gearbox with reverse or not is used.
The pitch under sailing in combination with motoring can be adjusted to optimize both the engine and the wind to achieve a higher speed and less fuel consumption.
During sailing the propeller blades are fully feathered to stop the propeller shaft from rotating and to minimalize the drag from the propeller.
Our high-performance propellers are specially designed and fine-tuned to comply with the highest tolerance classes. The propellers are supplied with 3 or 4 blades and diameters up to approx. 2200 mm.
Be aware that the controllable pitch propeller must be combined with a complete system.
