MESSAGES
17.1 AIS Safety Messages
You can send and receive messages via the VHF link, to a specified destination (MM-
SI) 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 mes-
sages 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.
