What lights and shapes must vessels at anchor display in a traffic separation scheme?

Vessels at anchor within a traffic separation scheme are required to display proper anchor lights and shapes to ensure their visibility and to communicate their status to other vessels. The rules dictate that these vessels should show an all-round white light or one ball shape during the night or in poor visibility. This is crucial as it distinguishes them from vessels under way and helps prevent collisions, particularly in congested areas like traffic separation schemes where many vessels operate.

Displaying the appropriate anchor lights and shapes enables other mariners to ascertain that the vessel is at anchor rather than under way, thereby enhancing safety and navigational awareness in busy shipping lanes. Recognizing these signals is a key part of safe maritime operation, reflecting the importance of adhering to established navigation rules.
