BOTH INTERNATIONAL & INLAND A vessel engaged in mine clearance operations shows special identity lights. Which is a requirement of these lights?

Correct Answer: Option A — in addition to the lights required for a power-driven vessel

Rule 27(f) mandates that a vessel engaged in mine clearance must display three green all-round lights in a triangle or three balls in a triangle, in addition to the lights or shapes prescribed for a power-driven vessel. These indicate that other vessels should not approach within 1,000 meters.
