If an unauthorized vessel approaches, what action should the POOW take?

When an unauthorized vessel approaches, it is vital for the Petty Officer of the Watch (POOW) to follow established protocol to ensure the safety and security of the area. Notifying the Officer of the Deck is an essential step because it allows for a coordinated response to the potential threat. The Officer of the Deck has the authority to implement further security measures and directs the overall action, which may include preparing for boarding procedures, alerting security forces, or determining a course of action based on the vessel's behavior and proximity.

Additionally, ensuring compliance with protocols can help in assessing the threat level and responding appropriately, safeguarding not only personnel but also the assets under watch. Engaging in a well-structured response based on established protocols is foundational in naval operations, where communication and following hierarchies are crucial for maintaining order and safety.
