Controllable pitch propellers are convenient when vessel the speed needs to be changed frequently, for example- entering or leaving port, leaving shore, or docking. In the case of an emergency stop, this type of propeller can immediately respond from full forward to full reverse movement.
- Enables the required vessel speed or thrust force to be obtained, even on vessels where load conditions vary greatly such as trawlers and towing vessels
- Minimises fuel consumption through efficient operation
- Avoidance of overtorque condition of the main engine by reducing the propeller pitch angle during operation in rough weather
