When are boats required to display navigation lights?

Boats are required to display navigation lights from sunset to sunrise and during periods of low visibility to ensure their visibility to other vessels and to avoid collisions. This regulation is essential for safety on the water, particularly during times when natural light is insufficient for observation.

During the hours of darkness or in conditions such as fog, rain, or heavy overcast skies, navigation lights help other boaters identify the type and position of a vessel, which is critical in preventing accidents. The specific lights required can vary depending on the length, type of boat, and the specific regulations in place, but the fundamental requirement is to communicate the vessel’s presence to others effectively.

Safety measures in busy harbors or when anchored for short periods may have different requirements, but the overarching rule is that if visibility is low or it is nighttime, lights must be displayed. Therefore, it is crucial for all vessels to be properly equipped with functioning navigation lights to maintain safe navigation practices.
