4.16 AIS Messages
You can send and receive messages via the VHF link, to a specified destination
(MMSI) or all AIS-equipped ships within communication range of your ship. Messages
can be sent to warn of safety of navigation, for example, an iceberg sighted. Routine
messages are also permitted. Short safety-related messages are only an additional
means to broadcast safety information. They do not remove the requirements of the
GMDSS.
