Which of the following is NOT a watch under the Officer of the Deck (OOD)?

The Chief Petty Officer position does not constitute a watch under the Officer of the Deck (OOD). The role of the OOD is primarily to oversee the safe and effective operation of the ship during their watch, with various roles reporting to them.

The Petty Officer of the Watch (POOW) and the Master-at-Arms of the Watch (MOOW) are specifically tasked with direct responsibilities under the OOD during watch conditions. The POOW assists by ensuring the watch-standing personnel are performing their duties, while the MOOW focuses on the security and safety aspects.

The Bag Checker, while a specific duty related to the watch, is also an appointed role under the supervision of the OOD during watch periods, ensuring that security protocols are followed. Thus, while the Chief Petty Officer plays an important leadership role and may support the OOD, they do not serve as a watch standing position under the OOD's command.
