How many copies does the 4100 form include for tracking purposes?

The 4100 form includes two copies for tracking purposes. One copy is retained by the boarding officer, while the other is issued to the vessel being boarded. This system allows for accurate tracking and documentation of boardings, ensuring that both the Coast Guard and the vessel have a record of the encounter. This dual-copy system facilitates communication and accountability between the Coast Guard personnel and the mariners they interact with, thereby enhancing operational efficiency and transparency during boardings.
