What is the function of the anchor chain?

The function of the anchor chain is primarily to connect the anchor to the ship while also providing necessary weight. This weight helps to ensure that the anchor holds firmly on the seabed, preventing the vessel from drifting when at anchor. The design of the chain, particularly its links, allows it to lay on the bottom in a way that maximizes holding power by preventing the anchor from pulling free due to wind or tidal movement. The combination of connection and added weight is essential for the effective performance of the anchoring system.

Measuring the depth of water is typically done using other methods, such as soundings or depth sounders. The anchor chain is not designed for this purpose. While propulsion systems are critical for a ship's movement, the anchor chain plays no role in propulsion. Lastly, although storage of excess line can be a consideration in anchoring operations, it is not the primary function of the chain itself, which is focused on securing the anchor. Thus, the primary role of the anchor chain is connecting and providing weight to secure the vessel effectively when at rest.
