What primary function does the vessel manifest serve?

The vessel manifest primarily serves to list all crew members and cargo aboard the vessel. This document is essential for ensuring accurate record-keeping and accountability during maritime operations. It helps authorities and port officials understand what is being transported, where it is coming from, and its destination. The inclusion of crew members' information is crucial for safety and security reasons, allowing for a complete overview of who is on board.

Having a comprehensive manifest is vital not only for operational logistics but also for compliance with international shipping regulations and customs laws. It provides the necessary information for customs officers at both the departure and arrival ports to facilitate inspections and enforcement of trade laws. This makes it clear why the primary function of the manifest centers around documenting the makeup of cargo and personnel onboard.
