Which watch station is specifically tasked with monitoring the safety of personnel boarding and leaving a vessel?

The Gangway Petty Officer of the Watch is specifically responsible for monitoring the safety of personnel as they board and leave a vessel. This role is crucial in maintaining security and ensuring that any movements in and out of the ship are conducted safely and efficiently. The Gangway Petty Officer oversees the gangway area, checks the identification of personnel, and ensures that proper protocols are followed to prevent unauthorized access and ensure the safety of both crew and visitors.

In addition to managing access to the vessel, the Gangway Petty Officer may also coordinate with other security personnel to address any potential risks or emergencies that might arise during the embarkation or disembarkation processes. This vigilance helps protect the vessel's crew, passengers, and overall operational integrity.

The other positions listed, while important within their own functions, do not have the specific duty of overseeing safety during personnel movements at the gangway.
