A chain consists of interlocking steel links designed to bear extreme tension and resist chafing. In seafaring, it is primarily used as anchor rode, where its immense weight creates a catenary curve that absorbs shock loads and helps the anchor dig into the seabed. Ship anchor chains are sized by the diameter of the link metal and often feature a central stud in each link to prevent kinking.

Insider tip
Sailors measure anchor chain in shots or shackles, which are typically 15 fathoms (90 feet) long, rather than by total feet.
