When a vessel is displaying normal navigation lights, what should you assume about its status?

When a vessel is displaying normal navigation lights, it indicates that the vessel is actively navigating. Navigation lights are used to signal a vessel's presence and its movement during times of reduced visibility, such as at dusk, at night, or in adverse weather conditions. Each type of light serves a specific purpose, helping to convey the vessel's status and intentions.

For example, specific light configurations can indicate whether a vessel is under power, sailing, or restricted in its ability to maneuver, but the presence of these lights generally communicates that the vessel is on the move. This assumption about the vessel being in navigation is crucial for the safety of other vessels in the area, as it informs them to exercise caution and maintain a safe distance. The presence of navigation lights does not typically correlate with being stationary, engaged in fishing, or moored, thus reinforcing the understanding that the vessel is operating and likely navigating through the water.
