Which light color indicates a port side vessel light when navigating at night?

In nighttime navigation, vessels are required to display specific colored lights to indicate their position and direction of travel to other watercraft. The red light indicates the port side, which is the left side of the vessel when facing forward. This convention is crucial for safe navigation during limited visibility conditions, as it allows vessels to identify each other’s course and make safe maneuvers.

The use of the red light is standardized in maritime navigation. When a vessel exhibits a red light on its side, it signifies that the vessel is approaching from the left side for another vessel. This helps prevent collisions by allowing each vessel to adjust its course accordingly.

Understanding these light color conventions is fundamental for anyone involved in boating activities, as recognizing the port side light can significantly enhance safety on the water.
