A ship anchor is more than just a heavy object dropped overboard—it’s a carefully engineered tool that uses weight, shape, and seabed interaction to keep a vessel stationary. When deployed, the anchor digs into the seabed, and tension in the anchor chain helps it maintain grip. The type of anchor and the nature of the sea floor—mud, sand, rock—determine how well it holds. For large ships, proper anchoring is essential for safe docking, loading, emergency stops, or riding out storms at sea.
