What should be done when the OOD assumes the watch on the bridge?

When the Officer of the Deck (OOD) assumes the watch on the bridge, logging the change of watch in the deck log is a critical procedural step. This action serves several important purposes: it ensures accountability, maintains a chronological record of events, and provides a reference point for ongoing operations. The deck log is an official record that documents the activities and conditions of the ship, and accurately reflecting the personnel on watch helps in maintaining an accurate history of the ship's operations.

While informing crew members is important for coordination and safety, and conducting safety drills or sending updates to the captain can be vital in certain situations, documenting the assumption of watch in the deck log is a fundamental requirement that formalizes the shift and contributes to effective command continuity and operational integrity.
