The anchor chain should be kept moderately taut during a Mediterranean moor to __________.

Correct Answer: Option C — prevent damage to the stern in the event of a headwind

In a Mediterranean moor, keeping the anchor chain taut is vital to prevent the vessel's stern from striking the pier. If the chain goes slack, wind or current can push the stern into the quay, causing structural damage to the vessel's transom or the pier's fendering system.
