CBKnot 7/64in Dyneema Rope 100/200/300 ft Hanks - Ultra Lightweight

In this review the CBKnot 7/64in Dyneema rope is evaluated for users who need a size-for-size replacement for wire rope with minimal weight penalty. The bottom line: this rope is ideal for rigging, winch and mooring applications where high strength, extremely low stretch and easy splicing matter most. Our review highlights how the Samthane coated Dyneema fiber delivers excellent abrasion resistance and floatation while remaining simple to inspect and handle for a wide set of marine, industrial and stage rigging tasks.

Key Features

• High strength-to-weight ratio: Provides wire rope strength at a fraction of the weight so it is much easier to lift and stow while maintaining load capability.
• Samthane coating: Enhances abrasion and cut resistance so the rope lasts longer in chafe-prone or split-drum winch applications.
• Low stretch and flex-fatigue resistance: Maintains line length and handling characteristics under load, improving control for winch and hoist tasks.
• Floats and is lightweight: The rope floats and is easy to manage on deck or in the field, reducing handling hazards and storage bulk.
• Easy to inspect and splice: The single-braid construction allows quick visual checks and straightforward splicing for terminals or custom rigging.
• Industry approvals: Type approvals and verifications mean this fiber meets standards expected for many marine and commercial uses.

Who It's For

This rope suits mariners, rigger crews, and industrial users who need a durable, lightweight line for winch, mooring, towing and lifting sling replacements where low stretch and high strength are essential. It is particularly useful on split-drum winches and for applications where ease of handling and spliceability are priorities.

Users who frequently need lines for H-bitts, capstans or cleats where heavy surging or rendering is required should consider alternative constructions, since this single-braid Dyneema is not recommended for high-surging capstan use. Those expecting heavy abrasion without protective fairleads may want to add sleeves or chafe protection despite the Samthane coating.

Pros & Cons

Pros

• Exceptional strength for size, replacing wire rope while weighing far less.
• Excellent abrasion and flex-fatigue resistance thanks to Dyneema fiber and Samthane coating.
• Easy to splice and inspect, which speeds repair and rigging tasks on site.
• Floats and has very low stretch, improving safety and control in many marine uses.

Cons

• Not recommended for H-bitts, capstans, or cleats when surging or rendering the rope is required.
• Non-jacketed construction may require external chafe protection in extremely abrasive conditions.

Frequently Asked Questions

Can this rope replace wire rope?
Yes, it is marketed as a size-for-size replacement with similar elastic elongation to wire rope but at about one-seventh the weight.

Is this rope suitable for winch drum use?
It is recommended for split-drum winch applications; avoid H-bitts, capstans or cleats if surging or rendering is required.

Does the rope need extra chafe protection?
The Samthane coating improves abrasion resistance, but external sleeves are recommended in severe chafe or sharp-edge situations.
