When is a lookout required on a vessel?

A lookout is required on a vessel at all times to ensure the safety of navigation and to avoid collisions. The role of a lookout is crucial as it provides the vessel's operator with additional situational awareness. A lookout helps in monitoring the surrounding waters, spotting other vessels, and identifying navigational hazards, which is essential regardless of the time of day or specific circumstances.

Having a lookout actively contributes to maintaining a safe watch, allowing for timely actions if a potential danger arises. This duty is especially important as it supports the principles of “safe speed” and “proper lookout” outlined in the navigation rules. While a lookout may be more visibly emphasized in situations like crossing busy channels or during docking maneuvers, the requirement stands firm that vigilance must be maintained at all times on the water.
