Built for the Demands of Anchoring
This 3/8 in. x 100 ft. three-strand twisted nylon anchor line is engineered to handle the dynamic shock loads that come with holding a boat at anchor. The nylon construction stretches under load and recovers, acting as a natural shock absorber that protects your cleats, bow eye, and anchor hardware from sudden surges caused by wind, wake, or tide.
The line arrives with a professionally spliced galvanized steel thimble at one end, ready to connect directly to your anchor shackle or chain leader without additional rigging work. Three-strand construction is easy to inspect, splice, and handle — a practical choice for everyday anchoring on boats up to approximately 25 ft.

Parts Desk Insights
Best use case: Everyday anchoring on recreational powerboats and sailboats up to approximately 25 ft. in protected to semi-exposed anchorages. The 3-strand twist is the traditional choice when shock absorption is the priority — ideal for overnight stays, lunch hooks, and locations with variable wind or tidal surge. For high-cycle use or boats where line handling speed matters, consider upgrading to a double-braid line.
Sizing note: 3/8 in. diameter is the standard working size for boats in the 18–25 ft. range. Pair with a minimum 4–6 ft. galvanized chain leader to reduce seabed chafe and improve anchor set.
Thimble compatibility: The pre-spliced galvanized thimble accepts standard 3/8 in. anchor shackles. Verify shackle pin diameter before connecting.
