Mooring Defender

The first lightweight braided mooring line with proven reduced risk of recoil upon seperation

Mooring Defender is a 12-strand mooring line made with Dyneema™ based on Samson’s unique, patented reduced recoil technology. Polyester fibers on the surface of the rope provide a high coefficient of friction, resulting in better grip. Dangerous "snap back," inherent to traditionally designed ropes, can cause severe injury to rope handlers and equipment in ship mooring operations. Engineered to meet the needs of our modern US military vessels, Mooring Defender is designed to absorb the energy released by the rope when it breaks, thus reducing the tendency of the rope to recoil. Like Samson’s other high performance mooring ropes, Mooring Defender has high strength, superior abrasion resistance and low elongation. Size for size, Mooring Defender is over twice the strength of traditional nylons and, unlike nylon, has no wet strength loss. When compared to 4-strand aramid rope, Mooring Defender is more flexible, has better UV resistance, is lighter weight and will not hockle.

When Mooring Defender is subjected to excessive tension loads, the lower elongating fibers will break first, transferring the load to the remaining specially designed control strands. This creates an indication of rope failure before the rope becomes completely separated. In a conventional rope, the rope will break without warning, causing unpredictable and potentially dangerous movements of the broken ends.
