Why is it recommended to attach 7-8 feet of chain to an anchor?

Attaching 7-8 feet of chain to an anchor is recommended because it helps lower the angle of pull, which effectively increases the holding power of the anchor. When the chain is connected to the anchor, it lies flat on the seabed, creating a horizontal pull that allows the anchor to set securely in the sediment. This positioning reduces the risk of the anchor pulling free from its hold, especially in rough conditions or strong currents.

Additionally, the chain serves to protect the anchor line from abrasion. When an anchor is deployed, the chain acts as a buffer between the anchor line and the seabed, minimizing wear and tear on the rope. Considering these factors, the advantage of using chain is primarily to enhance the overall security and stability of the anchoring system, which is essential for safe boating practices.
