When is a vessel less than 7 meters in length, anchored in an area where other vessels do not normally navigate, required to show anchor lights?

Answer: B — It is not required to show any anchor lights.

A vessel that is less than 7 meters in length and anchored in an area where other vessels do not normally navigate is not required to show anchor lights. This is in accordance with the regulations that recognize the size and operational conditions of smaller vessels. Since the vessel is in a location where there is minimal traffic and other boats are not expected to be present, the requirement for showing anchor lights is waived for safety and practical reasons. Larger vessels and those in areas with significant navigation must display anchor lights to ensure visibility and prevent collisions. In contrast, small vessels in isolated areas are exempt because the risk of encountering other vessels is low. Thus, any notion of displaying lights, whether it be a white light only or lights visible from all directions, does not apply to them in this specific context.
