If you only see a green light while boating at night, what might you be approaching?

Seeing only a green light while boating at night indicates that you are approaching a sailing vessel. In nautical navigation, the color of the lights displayed by vessels is crucial for understanding their orientation and type. A sailing vessel under sail at night will exhibit a green light on its starboard side (the right side when facing forward) and a red light on its port side (the left side).

If you only see the green light, it suggests you are looking at the starboard side of the vessel, confirming that it is indeed a sailing vessel moving in the opposite direction. Understanding these light configurations is essential for safe navigation at night, as they help you identify the type of vessels you're encountering and their relative positions.
