Spurs Ensures Fleet Protection Through Superior Cutting Performance!

The Cutting Edge Propeller Entanglement Solution
Enhance Your Bottom Line with Spurs. Our Cutter Systems, Trusted by the U.S. Navy and Global Commercial Fleets, Offer Unmatched Efficiency and Cost-effectiveness in Eliminating Propeller Entanglements. Instant Line and Net Cutting by Spurs Prevents Unforeseen Dry-docking Expenses Arising from Aft Seal Damage.
Protect The Environment and Avoid Fines
A propeller’s rotary screw action draws lines and nets directly to the hub where they are wound tighter and tighter, until they are forced into the oil seals and, in many cases, damage and destroy the sealing capabilities, releasing oil into the sea.
With Spurs cutter system, as the propeller rotates either toward or reverse, the lines or nets are grabbed by the rotating cutter and directed toward a waiting stationary cutter blade where, with each propeller revolution, they are instantly cut away before entanglement occurs.
Don’t take a chance!! Avoid expensive fines and down time from oil leakage resulting from line and net intrusion into aft oil seals (as shown here).

How Does It Work?
A Spurs cutter system comprises two primary assemblies: rotating cutting blades affixed to the vessel's propeller hub and a stationary cutting blade mounted on the rope guard or strut. Upon entanglement of lines or debris with the propeller, they are promptly severed with each shaft revolution.

How Does It Work?
With every Spurs installation you can count on step by step assistance - on site if needed - to ensure that your entanglement clearance system is properly installed.
Spurs cutters can stand up to the most severe cutting conditions and last for years. Spurs maintains a large inventory of cutter systems for vessels with short-notice dockings. We will present complete drawings of each installation, along with a quote, within a day of receiving 4 vital dimensions:
- 1Forward propeller hub and stern tube diameters
- 2Model and make of aft seal, etc. (see required measurements here)
We also provide drawings of the rope guard, where a minimum thickness of ¾” (or 19 mm) is required. The heavy rope guard will support the cutting of large nets and hawser lines when necessary.
