What should be done if a person without proper authorization is found onboard a vessel?

If a person without proper authorization is found onboard a vessel, isolating the individual and informing appropriate security authorities is crucial for maintaining maritime security. This action protects not only the vessel’s crew and passengers but also the integrity of sensitive information and equipment onboard. Unauthorized individuals can pose security threats, such as espionage, sabotage, or potential criminal activity.

By isolating the individual, you create a secure environment where the risk of potential harm can be minimized while awaiting further response from security authorities. This approach ensures that trained professionals handle the situation appropriately, determining the individual's intentions and threats while also preserving evidence if needed. The involvement of security authorities is essential, as they have the necessary resources and procedures to deal with unauthorized personnel effectively, thus reinforcing overall maritime security protocols.
