What is the primary responsibility of the Quartermaster of the Watch (QMOW)?

The primary responsibility of the Quartermaster of the Watch (QMOW) is to maintain the deck log. The deck log serves as the official record of all significant navigational and operational events that occur while the ship is underway or at anchor. This includes documenting the ship's position, course, speed, weather conditions, and any navigational hazards encountered, among other important details. The QMOW is crucial in ensuring that this log is accurate, timely, and compliant with Navy regulations.

Maintaining the deck log is essential for a variety of reasons, including maintaining situational awareness on board, providing historical records for future reference, and assisting with any investigations or inquiries regarding navigational incidents. This responsibility is pivotal for the safety and operational effectiveness of the ship.

The other options, while involving important roles in the Navy, do not pertain to the primary function of the QMOW. The responsibilities of commanding engineering, managing flight deck operations, or assisting the Tactical Action Officer belong to different roles within the ship’s command structure and do not align with the specific duties assigned to the Quartermaster of the Watch.
