Deck General USCG Question #4001 (Set 128)

You are arriving in port and are assigned to anchor in anchorage circle B-4. It has a diameter of 550 yards and your vessel's LOA is 449 feet. If you anchor in 9 fathoms at the center of the circle, what is the maximum number of shots of chain you can use and still remain in the circle?

Official USCG Answer & Rule Citation

Correct Answer: Option D — 4 shots

The circle radius is 275 yards (825 feet). Subtracting the 449-foot LOA leaves 376 feet for the chain's horizontal reach. At 9 fathoms (54 feet) depth, 4 shots (360 feet) provides a safe scope ratio of approximately 6.6:1, ensuring the vessel remains within the circle while the anchor flukes maintain a secure hold.
