What does a "starboard light" indicate on a vessel?

A "starboard light" indicates the right side of a vessel when viewed from the stern facing forward. In maritime navigation, vessels are required to display specific colored lights to communicate their position and orientation to other vessels, particularly at night or during poor visibility. The starboard light is green, and it plays a crucial role in ensuring safe navigation, allowing other vessels to determine the direction and movement of the vessel displaying the light.

This designation is part of the international maritime convention for safe navigation, which helps to prevent collisions by making it easier for mariners to understand which direction a vessel is heading. By having a standard color system—green for starboard (right) and red for port (left)—navigators can quickly assess a vessel's orientation relative to their own.
