When is a lookout required on a vessel?

A lookout is required on a vessel at all times to ensure the safety and navigation of the vessel. The presence of a lookout enhances situational awareness, allowing for the early detection of hazards such as other vessels, navigational obstacles, and changing weather conditions. This is particularly important because the visibility can vary greatly depending on factors like time of day, weather, and location.

Having a lookout at all times is a fundamental principle of safe seamanship governed by the international regulations for preventing collisions at sea (COLREGs). It is essential for maintaining the safety of not only the vessel itself but also other vessels and navigational interests in the area. By requiring a lookout in all conditions — whether it is day or night, clear or foggy — the regulations emphasize the need for constant vigilance while navigating waters.
