In what scenario is the deck log maintained by the Quartermaster of the Watch (QMOW)?

The deck log is a critical record that documents the ship's activities, positions, and other significant events throughout the operating day. It is specifically maintained by the Quartermaster of the Watch (QMOW) during underway operations. This period is when the ship is actively navigating and conducting operations at sea, allowing for the most detailed and timely entries regarding maneuvers, communications, and observations.

While at anchor, in maintenance periods, or in dry dock, the need for continuous and detailed logging by the QMOW diminishes. During these times, the operations are generally more stable or limited, which means the deck log may not require the same level of detail or frequency in entries as seen when the vessel is actively underway. Therefore, the correct scenario where the QMOW is responsible for maintaining the deck log is during underway operations, ensuring that all navigation and operational assessments are well-documented for reference and accountability.
