Who is responsible for maritime security on board a vessel?

The ship's master holds the ultimate responsibility for maritime security on board a vessel. This role is crucial in maintaining the safety and security of the ship, its crew, and cargo. The master is in charge of implementing security protocols, ensuring compliance with international regulations such as the International Ship and Port Facility Security (ISPS) Code, and making critical decisions in response to security threats.

While other roles on the ship, such as the crew members and the Chief Engineer, contribute to maintaining security, they operate under the authority and direction of the master. The crew is tasked with observing and reporting any suspicious activities and following the established security procedures, but it is the master who is ultimately accountable for the overall security strategy and its execution.

The port authority does play a role in maritime security, particularly concerning the security of port facilities, but once the ship is underway, responsibility shifts primarily to the ship's master. Thus, the master’s leadership is essential for effective maritime security management during a vessel's operations.
