When should navigation lights be activated on a boat?

Navigation lights should be activated at sunrise and sunset, or in conditions of bad visibility, such as fog, rain, or snow. This is crucial for the safety of both the vessel and other water users. During twilight or adverse weather, the lights make a boat more visible to others, reducing the risk of collisions. The regulations regarding navigation lights are designed to ensure that all vessels share the water safely, particularly in low-light conditions where visibility is poor.

While it may seem logical to activate navigation lights only at night, visibility issues can occur throughout the day. Bad weather can significantly impair visibility, making it essential to have lights on regardless of the time of day. Similarly, turning on lights before departing the dock might not be necessary unless you are setting out during low visibility or at dawn/dusk. Thus, the answer emphasizes the importance of using navigation lights in specific visibility conditions to promote safety on the water.
