Propeller Mounted Ship Cutters

Description

Spurs Line Cutter Systems use the propeller’s rotation and inertial force to power the cutting action. As the offending line enters the propeller vortex, it is wound toward the propeller hub. (NOTE: It is at this point that, without SPURS installed, the line would wind itself tighter and tighter, entering into the space between propeller hub and rope guard, where it can damage the oil seals.) Instead, the line is engaged by the rotating cutter blades and delivered to the stationary cutter blade. The sudden resistance sensed by the stationary cutter forces a cam action which causes the blade to be pushed outward, meeting the rotating blade and severing the obstruction.
