"Environmentally Responsible SPURS Line and Net Cuter Systems is meeting the challenge by preventing oil seal damage from line and net intrusion in the seal and bearing area of medium and large vessles. Since the Oil Pollution act of 1990 (imposing heavy penalties for oil leaks), the US Coast Guard has been ordered to advise vessels that " the source of the leak must be immediately secured." Whether long line, drift netting, floating tow lines or dock lines, SPURS propeller mounted Large and Medium Vessel Line and Net Cutter is designed to cut away lines, nets, etc. before entanglement begins. This minimizes costly diving charges, bearing the seal damage, and idle dry-dock time. As line is grabbed by the propeller, it is wound toward the propeller hub and picked up by the rotating cutter blade, where it is instantly cut, forward to reverse, and washed away, clearing the propeller with each revolution.
