Are day signals required for vessels that are anchored?

The correct answer, which states that day signals are not required for vessels that are anchored, is based on the regulations that focus on navigation safety and effective communication of a vessel's status. When a vessel is at anchor, it is generally not in motion and thus does not pose the same navigational risks as a vessel underway.

The International Regulations for Preventing Collisions at Sea (COLREGs) establish specific signaling requirements aimed at preventing accidents. For anchored vessels, the regulations specify that they need to display anchor lights at night but do not necessitate the use of day signals during the daytime. This is because anchored vessels are not likely to confuse their status with vessels that are underway and may need to display their signaling requirements to convey information to other mariners.

Day signals are typically more important for vessels that are actively navigating or maneuvering in waters where other vessels could be present. In busy waterways, although additional visual signals may be good practice for safety, the regulations do not mandate day signals for anchored vessels. Similarly, the requirement based on the time of year is not applicable, as the rules governing anchored vessels remain consistent regardless of seasonal changes. Thus, the answer confirming that day signals are not needed for anchored vessels aligns with the standard practices and
