BOTH INTERNATIONAL & INLAND Which lights shall a 200-meter vessel exhibit when at anchor?

A In the forepart of the vessel, a 225-degree white light

B In the forepart of the vessel, a 112.5-degree white light

C Working lights to illuminate the decks

D In the after part of the vessel, a 112.5-degree white light

AI Explanation

The correct answer is C) Working lights to illuminate the decks. According to the International Regulations for Preventing Collisions at Sea (COLREGS), a vessel 200 meters or more in length when at anchor must exhibit, in the forepart of the vessel, a 225-degree white light. Options A, B, and D do not correctly describe the required anchor lights for a 200-meter vessel. Instead, a 200-meter vessel at anchor should display working lights to illuminate the deck, which is the requirement specified in answer choice C. These working lights help make the vessel visible and prevent collisions.
