Which of these is NOT a phase of boarding activities?

The phase of boarding activities that is not recognized as a standard component is the one related to arrest procedures. Boarding activities typically consist of several key phases that guide the process and ensure that it is conducted safely and effectively.

Pre-boarding is crucial as it involves planning and preparing for the boarding operation, which includes gathering intelligence, assessing risks, and ensuring that all team members understand their roles and the mission objectives. The introduction phase follows, where the boarding team establishes initial contact with the vessel and communicates their presence and intentions to the crew.

Disembarkment is also a significant phase, occurring after the boarding operation is complete. It involves safely exiting the vessel and returning to the boarding platform or vessel, ensuring that all personnel and equipment are accounted for.

Arrest procedures, while they may occur in the context of law enforcement during a boarding operation, do not constitute a distinct phase of the overall boarding activities themselves. Instead, they would be part of the protocols or actions taken should security threats arise and further action need to be taken. Thus, they do not fit within the standard phases outlined for typical boarding operations.
