Mooring

Double Braid

represent the industry standard in dual-layer rope construction, engineered to deliver exceptional energy absorption, low stretch, and superior abrasion resistance across marine docking, mooring, and heavy rigging applications.

Features a precision-braided outer jacket surrounding a braided core, providing dual-layer protection, smooth handling, and superior snag resistance over chocks and cleats.

Counter-balanced inner and outer braid geometries completely eliminate line rotation and hockling under tension, ensuring seamless operation on winches and capstans.

Available in high-stretch nylon for maximum surge damping, or ultra-low-stretch HMPE/Polyester for rigid, wire-replacement stability under heavy load.

Factory-treated with proprietary coatings to seal out marine grit, reduce internal strand-on-strand friction, and enhance external abrasion resistance.

Design

A 2-in-1 double braided construction consisting of a braided inner core enclosed within a braided outer cover. Depending on the fiber composition, the load is either shared equally between the core and jacket (pure Double Braid) or carried entirely by a high-modulus core with the jacket acting as protective armor (Core-Dependent Double Braid).

Application

Mooring & Docking: Primary dock lines, spring lines, and mooring pendants requiring high energy absorption or high breaking strength.
Superyacht & Aesthetic Rigging: Premium color-matched and black polyester/nylon lines for clean deck visuals and smooth winch handling.
Tug, Towing & Escort: Heavy-duty escort lines, face lines, and towing strops exposed to high-friction rendering over fairleads.
Winch & Crane Operations: Core-dependent HMPE double braids utilized as wire-rope replacements for heavy-lift cranes and deck winches.

Type Key

Construction Type	Core Material	Cover Material	Primary Performance Benefit
Standard Double Braid	Nylon or Polyester	Nylon or Polyester	Equal core/cover load sharing; excellent flex fatigue & shock damping.
Hybrid Double Braid	Polypropylene Blend	Poly/Polypropylene	Lightweight floating construction with good wet strength and economy.
Core-Dependent Double Braid	HMPE or Aramid	Polyester, HMPE, or Blend	Core holds 100% of working load; cover provides thermal and abrasion shielding.

Materials

High-Tenacity Nylon: Maximum energy absorption and elastic stretch, ideal for buffering heavy surge loads in harbor moorings.
Marine-Grade Polyester: High wet-strength retention, low elongation, and superior resistance to sunlight and chemicals.
HMPE (Dyneema®): Ultra-high molecular weight core fiber providing extreme strength-to-weight ratios with minimal stretch.
Aramid (Technora®/Kevlar®): Heat and cut-resistant fibers designed for extreme friction environments and thermal exposure.
Polypropylene & Blends: Buoyant, economical fiber blends designed for floating line requirements.

Construction

2-in-1 Braid-on-Braid: Coordinated core and cover pitch angles ensure balanced stress distribution and high flexibility.
Coated vs. Uncoated Options: Available with Samthane™ color-coded polyurethane coatings or soft-hand uncoated finishes.
Factory Splice Terminations: Pre-spliced with soft eyes, thimbles, or custom heavy-duty chafe protection upon request.

Scope of delivery

Custom Lengths & Master Spools: Delivered in pre-cut custom lengths with certified eye splices or standard 600 ft / 1200 ft spools.
Certification: Factory test certificate with verified breaking strength (ABS / DNV type approval available on request).
Maintenance & Splicing Manual: Includes official Samson double-braid splicing guidelines and deck inspection procedures.
