What is the lighting requirement for large vessels in a "special anchorage area"?

In a "special anchorage area," large vessels are required to display all navigation lights that are typically mandated for their size and type. This requirement ensures that the vessels are clearly visible to other mariners and helps prevent collisions. The purpose of having comprehensive lighting at anchorage is to maintain safety and situational awareness in areas where vessels may be at rest. By displaying all navigation lights, vessels contribute to the overall safety of navigation in the vicinity.

The other options do not align with established regulations for anchorage areas. Restricting lighting to red lights would limit visibility and could pose safety hazards. Showing no lights would make the vessel virtually invisible, increasing the risk of accidents. Requiring a minimum of three white lights would not be sufficient or appropriate, as vessels might have specific configurations that necessitate different lighting arrangements beyond just a minimum number of lights.
