ABSTRACT:
A line cutting device for use with a hydrodynamic propeller has a blade (5) fixed to a vessel having the propeller. Three rotating blades (22) extend from a hub fixed around the propeller's shaft. The fixed and rotating blades are arranged for line shearing action. Each of the rotating blades has four apertures (21) extending from front to back through the blade for passage of water therethrough towards a respective blade of the propeller. The apertures are arranged to alleviate cavitation on the propeller blades.
