What color is the starboard navigation light?

The starboard navigation light is green. This color coding is a standard used internationally to indicate the right side (starboard) of a vessel. When viewed from the front of a boat, the green light helps in determining the direction of movement of other vessels at night and in conditions of reduced visibility.

Understanding the purpose of navigation lights is crucial for safe navigation. The starboard light is typically paired with a red light on the port side, which helps to easily identify the position and heading of a vessel. When approaching another boat, seeing a green light indicates that the other boat's starboard side is facing you, which is critical to understanding right-of-way rules on the water.
