What distinguishes special anchorage areas in terms of lighting requirements for smaller vessels?

In special anchorage areas, the lighting requirements are indeed different for smaller vessels, specifically those under 20 meters in length. These areas serve to accommodate smaller vessels and provide certain navigational benefits. One of the primary distinctions is that vessels under this length typically are not required to display navigation lights while at anchor in these designated locations. This regulation is designed to simplify the requirements for smaller boats and reduce the potential for interference with other vessels while they are not underway.

The focus on easing navigation requirements is crucial for smaller operators who may not have the same access to resources as larger commercial vessels. Additionally, this exception maintains safety by minimizing confusion that could arise from unnecessary lights, since the environmental conditions in special anchorage areas often warrant simplified navigation.
