How many turns of wire normally mark either side of the detachable link 45 fathoms from the anchor?

Correct Answer: Option C — 3

Marking systems for anchor chain are standardized to ensure safety. At 45 fathoms, the detachable link is marked with three turns of wire on the third stud from each side. This provides a clear, durable, and easily identifiable reference point for the crew to monitor the amount of chain veered.
