What is the purpose of the Warn step in dealing with an NCV?

The purpose of the Warn step in dealing with a Non-Compliant Vessel (NCV) is to provide an unambiguous signal indicating consequences. This step is crucial because it clearly communicates the potential repercussions of the NCV's actions. When the crew issues a warning, it serves not only as a signal of the seriousness of the situation but also reinforces the authority of the Coast Guard and the requirement for the vessel to comply with lawful orders.

Providing a clear warning allows the NCV to understand the implications of its non-compliance and gives the crew an opportunity to de-escalate the situation before moving to more forceful measures. Effective communication at this stage can often lead to voluntary compliance by the vessel without the need for further enforcement action, which supports safe operations and minimizes the risk of confrontation.

The other choices focus on actions that take place either after a warning has been given or that do not specifically emphasize the communication of consequences associated with non-compliance.
