What does the term 'hostile boarding' refer to in vessel security?

The term 'hostile boarding' in vessel security specifically refers to a situation where unauthorized personnel board a vessel with the intent to confront or challenge the crew, often for purposes of theft, piracy, or other criminal activity. This type of boarding is typically aggressive and poses a direct threat to the safety and security of the ship and its occupants.

Understanding this concept is crucial for maritime security, as it helps distinguish between legitimate boardings that are conducted by authorized personnel—such as law enforcement or security agencies—and those that are threats to the vessel's integrity. The distinction helps in developing appropriate responses and security measures to protect against such events.
