A vessel less than 20 meters in length at anchor at night in a "special anchorage area designated by the Secretary" must show what lights?

A vessel that is less than 20 meters in length and at anchor in a special anchorage area designated by the Secretary is not required to show any lights at night. This regulation allows for reduced lighting requirements in specific areas where safety and navigational awareness can be managed in a different manner than in more congested or regulated waterways.

This rule recognizes the unique circumstances of special anchorage areas and provides flexibility for smaller vessels. In these designated areas, the risks of collision and navigation issues are lower, allowing vessels to anchor without the need for the usual lighting requirements that apply in other situations. It’s important for mariners to be aware of these regulations to ensure compliance and maintain safety.
