What is the primary function of a ship's anchor chain?

• A. To rotate propeller
• B. To provide a secure mooring
• C. To lift the ship onto dry dock
• D. To measure depth

Answer: (B)

Anchor chains provide a secure mooring by linking the ship to its anchor and transmitting the pull from wind, waves, and current into the seabed. The chain’s weight helps the anchor set and stay buried, and the length of chain (scope) relative to water depth gives enough leverage to keep the ship from drifting and to absorb shocks. This is the primary function—keeping the vessel in a fixed position while at anchor. The other options describe propulsion, lifting for dry docking, or depth measurement, which aren’t the chain’s purpose.
