Which position handles the ship's deck log entries certification for correctness before commanding officer's signature?

The navigator is responsible for maintaining the ship's navigational records, including the deck log. This position involves ensuring that all entries in the log are accurate and complete, as these records are crucial for operational accountability and decision-making. The navigator verifies the correctness of the log entries before they are presented to the commanding officer for signature, signifying that they are accurate representations of the day's operations.

In contrast, the engineer typically focuses on the mechanical and operational readiness of the ship. The quartermaster assists in navigation and watch standing duties but does not primarily handle the final verification process of the deck log. The command duty officer oversees the ship's operations during their watch but relies on the navigator to ensure the log's correctness. Thus, the navigator's role is critical for ensuring the integrity of the deck log prior to the commanding officer's signature.
