When anchored in a special anchorage area, what must vessels less than 20 meters do?

In a special anchorage area, vessels that are less than 20 meters in length are not required to display navigation lights or sound whistle signals. This regulation allows for a more relaxed standard for smaller vessels in these designated areas, distinguishing them from general anchoring areas where more stringent requirements are in place.

The purpose of special anchorage areas is often to provide safe haven for small vessels, particularly in locations where they might be less visible to larger ships or in zones where navigation is simplified. By not requiring lights or sound signals, the regulations help minimize confusion and the potential for accidents, especially in areas where vessel traffic is limited and visibility is already enhanced due to the nature of the anchorage.

Other options, while relevant to general navigation safety, do not apply specifically to the requirements for small vessels in special anchorage areas, highlighting the unique considerations given to smaller crafts in these designated locales.
