What are the primary duties of the Officer of the Deck (OOD)?

• A. The safety, security, and proper operation of the unit
• B. Maintaining deck logs and weather reports
• C. Conducting crew evaluations
• D. Coordinating external port calls

Answer: (A)

The Officer of the Deck is responsible for the safety, security, and proper operation of the unit during their watch. They act as the commanding officer’s on-scene representative, maintaining overall situational awareness, directing deck operations, and ensuring navigation, movement, and systems are managed according to approved procedures. The OOD monitors for hazards, enforces standing orders, coordinates with the helm and other watchstanders, and has the authority to order corrective actions, initiate alarms, and lead emergency responses as needed until relief arrives. The core aim is to keep the ship safe, secure, and capable of performing its mission.

Logs and weather reports, while important, are duties more specific to the deck leadership and specialists (like the Quartermaster and weather observer). Conducting crew evaluations is a leadership and training task, not the primary watch-standing function of the OOD. Coordinating external port calls involves broader planning and operations coordination, not the immediate on-deck responsibility of leading the watch to maintain safety and proper operation.
