What is the primary purpose of navigation lights on a boat?

The primary purpose of navigation lights on a boat is to help prevent collisions at night. These lights serve as a crucial safety feature, providing visual signals to other vessels regarding the boat’s position, direction, and activity. Each navigation light has a specific color and placement that convey vital information to other boat operators. For instance, a red light indicates the port (left) side of the vessel, while a green light signifies the starboard (right) side. A white light indicates the stern (rear) and is visible from all directions.

By displaying these lights correctly, boaters can communicate their movements and intentions, significantly reducing the risk of accidents during low visibility conditions such as night or fog. This adherence to proper navigation lighting is vital for safe boating practices and is often mandated by maritime regulations.
