The term "Mooring Chain Assembly" in marine navigation refers to a critical safety
practice involving the securing of anchor chains. In this context, the forelock is a
small pin or bolt that prevents the anchor chain from accidentally disengaging. The
chain, vital for anchoring stability, is threaded through the anchor shackle, and
the forelock is then inserted to lock it in place. This precautionary measure
ensures the anchor remains securely attached to the vessel, preventing unintended
drifting or dragging. Adhering to the "Chain N Forelock" principle is paramount in
maritime operations, emphasizing the importance of meticulous attention to detail
for the safety of both crew and vessel.
