What is the characteristic of a light vessel at anchor?

A light vessel at anchor displays appropriate anchor lights, which are essential for signaling its presence to other vessels. These lights are typically a combination of navigation lights to ensure visibility in various conditions and to convey its status as a stationary vessel. The specific configuration of these lights usually includes a white anchor light positioned at the masthead or in a similar location, which can be seen from a distance.

This is crucial for safety on the water because it helps prevent collisions and allows other vessels to navigate safely around the anchored light vessel. The appropriate use of anchor lights reflects adherence to the International Regulations for Preventing Collisions at Sea (COLREGS), which set forth the required lighting for vessels at anchor to communicate effectively with other surface traffic.
