ABSTRACT:
The propeller comprises a propeller shaft mounted so that its position in relation to the ship's hull can be varied both at stopovers or in transit. The propeller shaft carries propeller blades of such a configuration that, while going into the water, they position their face sides normally to the longitudinal center plane of the ship. According to the invention the propeller blades can change position relatively to the longitudinal center plane or to the midship section plane or simultaneously to both the planes, thereby increasing speed, maneuverability, efficiency, and safety.
