Anchor Chains for Boats
Anchor chains are a critical part of a boat’s ground tackle, connecting the anchor to the boat. Chain weight, strength, and durability all contribute to safer anchoring by improving holding power and reducing shock loads from wind and waves.
Fisheries Supply stocks a broad range of marine-grade anchor chains and accessories used by boaters.
Key Takeaways
- High Test, BBB, and Proof Coil chains serve different boat sizes and loads.
- Material choice affects corrosion resistance, cost, and longevity.
- Chain stoppers and snubbers help protect windlasses from shock loads.
Types of Boat Anchor Chains
Different boats and anchoring systems call for different chain styles. The most common anchor chain types used in marine applications include:
- High Test (HT) Chain – High-strength chain designed for larger boats and heavier anchoring loads.
- BBB Chain – Short for “Triple B,” this chain offers a balance of strength and flexibility and piles neatly into chain lockers.
- Proof Coil Chain – A general-purpose option suited for lighter anchoring needs and smaller boats.
Materials Used in Anchor Chains
Marine anchor chains are manufactured from several materials, each with specific advantages depending on the environment and application.
- Galvanized Anchor Chain – Zinc-coated steel that provides strong corrosion resistance and is widely used in saltwater environments.
- Stainless Steel Anchor Chain – Offers excellent corrosion resistance and a polished appearance, typically at a higher cost.
- Vinyl-Coated Chain – Adds surface protection for specific uses but may require more frequent replacement over time.
Importance of Chain Stoppers
A chain stopper secures the anchor chain when the boat is moving. Its primary role is to relieve strain on the windlass. For proper alignment, the chain stopper should be installed in a straight line between the bow roller and the anchor windlass.
When anchored, using a snubber instead of the chain stopper is recommended to reduce shock loads and protect the windlass from sudden forces.

Frequently Asked Questions
What is an anchor chain called?
The nautical term is anchor rode. The anchor rode connects the anchor to the boat and may be made of chain, rope, or a combination of both. Larger boats and long-range cruisers often use all-chain rode.
How much is a shot of anchor chain?
Anchor chain is measured in shots in the United States and shackles in England. One shot equals 15 fathoms, or 90 feet (27.5 meters), of chain.
What are common anchor chain accessories?
Common anchor chain accessories include shackles, swivels, quick links, and snubbers. These components help prevent twisting and reduce shock loading in the anchoring system.
