In the after part of the vessel, a 135° white light
B
In the forepart of the vessel, a 225° white light
C
In the fore part of the vessel, a 135° white light
D
Any available working lights to illuminate the decks
AI Explanation
The correct answer is D) Any available working lights to illuminate the decks. According to the International Regulations for Preventing Collisions at Sea (COLREGS), a vessel at anchor over 200 meters in length is required to exhibit "in the fore part, where it can best be seen, a white light in the shape of a cone, apex downwards." There is no requirement for a 135° or 225° white light. The key is to use any available working lights to illuminate the vessel's decks, rather than displaying specific navigation lights, in order to make the vessel visible to other vessels in the area.
