Question: 1 / 400

Which of the following is required to be shown by a vessel at anchor during the night?

Only a sternlight

Sidelights and sternlight

An all-round white light

When a vessel is at anchor during the night, it is required to display an all-round white light. This regulation is put in place to ensure that other vessels can easily see the anchored vessel and avoid potential collisions. The all-round white light should be positioned where it is visible from all angles, allowing other mariners to recognize that the vessel is not under way and is securely anchored.

While it may seem reasonable to think that sidelights or other configurations could suffice, those lights are intended for vessels that are navigating and underway, not for those at anchor. By using an all-round white light, not only is visibility maintained, but it also conveys clear information about the status of the vessel, which is crucial for safety in maritime navigation.
