Because mooring a Navy ship to a pier is not always possible or desirable, anchors often are used to secure a vessel in place. The equipment associated with anchoring is called ground tackle and includes the anchors themselves, the chains used to attach them to the ship, and the windlasses used to weigh anchor (lift them back on board).
An anchor is a type of hook that embeds itself into the sea bottom. The body of the anchor is called the shank, and the flukes are the “teeth” that actually bite into the bottom. Older-style Admiralty-pattern anchors have a stock, which is a crossbar that prevents the anchor from lying flat, thus making it easier for the flukes to dig into the sea floor.
The hawsepipe serves as a passage for the anchor chain, leading from the forecastle deck to the outer surface of the ship’s hull closer to the water. Modern anchors are stored in the lower end of this tube. The unused portion of the anchor chain is stowed belowdecks in a large compartment called the chain locker.
