4.16 How to Use AIS Messages
You can transmit and receive messages via the AIS, to a specified destination (MMSI)
or all ships in the area. Messages can be sent to warn of safety of navigation, for ex-
ample, an iceberg sighted. Routine messages are also permitted.
Short safety related messages are only an additional means to broadcast safety infor-
mation. They do not remove the requirements of the GMDSS.
