Abstract
The marine vessel propeller has vanes or blades containing outer edges which are bounded by circularly domed outer surfaces which coact with a spherical zone of a spherical surface formed at the inner surface of the nozzle. The common central point of the spherical zone and of the circularly domed outer surfaces of the vanes or blades is located at the intersection point of the vane axes and about each of which vane axis the related propeller vane or blade is pivotable. The intersection point of such vane axes is located on the propeller axis.
