What should the POOW do if they encounter an unidentified vessel?

When a Petty Officer of the Watch (POOW) encounters an unidentified vessel, the appropriate action is to notify the Officer of the Deck (OOD) and monitor the vessel. This is crucial because the OOD has the overall responsibility for the safety and navigation of the ship. Monitoring the unidentified vessel allows the POOW to assess its behaviors and actions, which is important for maintaining situational awareness.

By keeping the OOD informed, the ship can take necessary measures to ensure safety, such as adjusting course, establishing communications with the vessel, or preparing for potential evasive actions. This prudent and cautious approach emphasizes the importance of communication and coordination in maritime operations, ensuring that any unidentified or potentially suspicious vessel is handled appropriately without escalating the situation unnecessarily.
