You are in the middle of the ocean and spot a green light 2 points to starboard. Knowing that the light is not from a buoy, what can you assume that you are looking at?

Correct Answer: Option D — The starboard side of another vessel

Under COLREGS, a green light indicates the starboard side of a power-driven vessel. Since the light is 2 points to starboard, you are viewing the starboard side of another vessel. This identification is crucial for determining the 'give-way' or 'stand-on' status during potential crossing or overtaking situations at sea.
