Which of the following is NOT one of the parameters for the Officer of the Deck?

The role of the Officer of the Deck (OOD) is critical in ensuring the safe and efficient operation of a vessel. The choice pertaining to being subordinate to the Executive Officer is not an accurate representation of the responsibilities of the OOD. The OOD is a position that operates independently during their watch, making immediate decisions about the safety and navigation of the vessel.

The OOD is responsible for the safety of the ship, which encompasses a wide range of duties from navigation to monitoring the condition of the crew and the vessel itself. They also play a vital role in executing performance of duty regulations, overseeing the crew to ensure compliance with these standards. Commanding all personnel, except for the Executive Officer, captures the aspect of the OOD's authority during specific watch periods, as they lead the crew and coordinate actions necessary for operation.

Thus, the statement about being subordinate to the Executive Officer does not accurately reflect the OOD's operational command responsibilities during their watch. Instead, the OOD leads the deck operations and is directly accountable for the vessel's conduct under their supervision.
