Mooring

Multi-strand line

represent the industry benchmark for single-braid, plait, and twisted rope constructions engineered for marine mooring, towing, and rigging applications.

8-strand plait and 12-strand single-braid geometries inherently eliminate rotation and hockling under extreme tension, preventing dangerous snapping and fatigue.

Open single-layer braid design allows rapid, tool-free visual inspection of internal fibers and simple field splicing for gasas (eye splices) and line repairs.

Surface-treated with high-durability polyurethane coatings to dramatically reduce internal fiber friction, withstand deck abrasion, and resist UV degradation.

Engineered across a full range of high-performance materials—from buoyant HMPE (AmSteel®-Blue) to energy-absorbing Nylon (Pro-Set™) and heat-resistant Aramid (Tech-12™).

Design

Uncovered single-braid (12-strand), braided plait (8-strand), and conventional twisted (3-strand) torque-balanced synthetic lines designed for direct surface grip, smooth winch drum spooling, and maximum strength-to-weight performance.

Application

Primary & Secondary Mooring: Dock lines, spring lines, and permanent mooring pendants for recreational boats, superyachts, and commercial vessels.
Tug & Barge Operations: Heavy-duty tie-down lines, lock lines, and towing strops for inland river towboats and ocean tugs.
Anchor & Fender Lines: High-elasticity twisted and braided lines for anchoring systems and fender tie-downs.
High-Load Rigging & Winch Lines: Wire rope replacement using ultra-lightweight HMPE lines for winches, cranes, and heavy lifts.

Type Key

Construction Type	Strand Count	Structural Geometry	Primary Performance Benefit
3-Strand	3 Cordones	Traditional Twisted Lay	High elongation/elasticity; easy knotting and economical general mooring.
8-Strand Plait	8 Cordones	Square/Plait Braid	Fully torque-free; highly flexible; flakes compactly into chain lockers.
12-Strand	12 Cordones	Single Braid (Hollow Core)	Maximum strength-to-weight ratio; zero rotation; ultra-fast field splicing.

Materials

HMPE (Dyneema®): Ultra-High Molecular Weight Polyethylene delivering strength equivalent to steel wire at 1/7th the weight with zero water absorption.
High-Tenacity Nylon: Superior elasticity and energy absorption, ideal for absorbing shock loads in surge-heavy moorings.
Polyester & Blends: Excellent UV resistance, low stretch, and high wet-strength retention for permanent dock lines and halyards.
Polyolefin & Co-Polymer: Lightweight, floating synthetic fibers offering cost-effective strength for river and commercial workboats.
Aramid (Technora®/Kevlar®): Extreme heat, cut, and abrasion resistance for high-friction winch and capstan applications.

Construction

Non-Jacketed Single Braid: Direct load-bearing strand alignment without external jacketing, reducing weight and overall line diameter.
Factory Pre-Spliced Eyes: Available with factory-certified soft eyes, heavy-duty thimbles, or protective chafe sleeves on request.
Color-Coded Identification: Molded-in color coatings and tracer threads for rapid diameter, material, and load rating verification on deck.

Scope of delivery

Custom Length or Full Spool: Delivered in pre-cut custom lengths with spliced ends or standard 600 ft / 1200 ft master spools.
Certificate of Conformance: Samson factory test certificate verifying breaking strength (ABS / DNV certified options available).
Splicing & Maintenance Manual: Official Samson field splicing instructions and inspection guide.
