BOTH INTERNATIONAL & INLAND Which vessel, when anchored at night, would NOT be required to show anchor lights?

Correct Answer: Option C — A vessel dredging

Rule 27(d)(v) states that a vessel engaged in dredging or underwater operations, when at anchor, shall exhibit the lights or shapes prescribed in Rule 27(d)(i) instead of the anchor lights prescribed in Rule 30. This ensures the vessel's operational status remains clearly visible to other traffic.
