An anchor chain is a type of chain used to connect an anchor to a vessel, providing stability and security when the vessel is at anchor. Made from high-strength steel, anchor chains are designed to withstand the forces of waves, wind, and currents, and to securely hold the vessel in place. Anchor chains come in a range of sizes and configurations to suit different types of vessels and anchoring conditions. The links of an anchor chain are typically made from a high-strength steel alloy that is resistant to corrosion, abrasion, and wear. The links are designed to interlock securely, creating a strong and reliable chain that can withstand the stresses of being at anchor. The thickness of the chain and the size of the links are critical factors in determining the strength and durability of the chain.
