BOTH INTERNATIONAL & INLAND If you anchor your 25-meter vessel in a harbor, what lights must you show?
AI Explanation
The correct answer is A) One all-round white light.
When a vessel is at anchor, the International Regulations for Preventing Collisions at Sea (COLREGS) require the display of an all-round white light at or near the bow of the vessel. This is to indicate the vessel's position to other vessels in the area and help prevent collisions.
The other answer choices are incorrect because a red light is not the appropriate color for an anchored vessel, two white lights are not necessary, and displaying only the deck house lights would not meet the COLREGS requirements for an anchored vessel.
