Passenger and Crew Count
The purpose of the Passenger and Crew Count message is for a ship to report the number of persons on board separated into passengers and crew, e.g., upon request by a competent authority.
- This message is addressed only; sent to the competent authority requesting the information.
- The total number of people onboard the vessel is the sum of the crew (anyone not a passenger) and passenger numbers.
- The Message Linkage ID can be used to link additional text (e.g., a separate text message). However, the same source MMSI needs to be included in both the Passenger and Crew Count and Linked Text messages).
- The UTC day and time fields reflect the time the message is prepared; the number of crew and passengers in the message shall be whatever they were at this time.
- If a message is received with a more recent day/time, then the older message should be discarded and the newer data used.
