What color light is designated for the Starboard side of a vessel?

The color light designated for the starboard side of a vessel is green. This is part of the standard navigation lights that vessels are required to display to indicate their position and orientation to other vessels, particularly at night or in poor visibility conditions.

In the International Regulations for Preventing Collisions at Sea (COLREGs), vessels are required to show specific colored lights: a green light on the starboard side (right side when facing forward) and a red light on the port side (left side when facing forward). This color-coding helps other vessels determine the orientation of the vessel, thus aiding in safe navigation and collision avoidance.

Additionally, the meaning behind these color designations is important for understanding how vessels communicate their direction. If a vessel is showing its green light, it is approaching from the starboard side, which is crucial information for operators of other vessels to know in order to make safe navigational decisions.
