An anchor chain's main purpose is to keep a ship from drifting and to allow it to stay put in different water conditions. It also transfers the anchor's holding force to the ship's hull.

A marine anchor is used on a ship to securely hold it in place in a body of water by attaching itself to the seabed, preventing the vessel from drifting due to wind, currents, or tides; essentially acting as a "brake" to keep the ship stationary in a desired location, particularly when at rest in a harbor or anchorage.
