What is a reason for calling the Commanding Officer?

The reason for calling the Commanding Officer relating to the status of watertight frames is critical due to the implications for ship safety and integrity. Watertight integrity is essential for preventing flooding and ensuring the vessel can withstand various maritime conditions. If there are any issues concerning the watertight frames, immediate communication with the Commanding Officer is necessary, as this information could affect the operational readiness of the vessel and the safety of the crew and passengers.

While on-deck training, routine maintenance checks, and general protocol questions are important matters, they typically do not require the immediate attention of the Commanding Officer unless there is a specific situation that directly impacts safety or could have significant operational consequences. The status of watertight frames, however, is directly tied to the vessel's structural integrity and overall safety, making it a priority to communicate any issues promptly.
