What is the role of navigation lights on a boat?

The role of navigation lights on a boat is primarily to indicate the boat's position to other vessels. Navigation lights are essential for safe boating, especially during low visibility conditions such as nighttime or inclement weather. They help other boaters see your craft and understand its direction of travel and whether it is moving or anchored.

Each type of navigation light has specific meanings; for example, a red light on the left side and a green light on the right side of the boat signify its orientation. This visual information helps to prevent collisions on the water, allowing mariners to determine what other vessels are doing, assess potential risks, and navigate safely.

While navigation lights can indirectly assist with docking and mooring by making the boat more visible, their primary function is to provide important positional information to enhance safety on the water. Other options listed do not accurately reflect the primary purpose of navigation lights.
