4.14 Messages
You may transmit and receive messages via the VHF link, to a specified
destination (MMSI) or all ships in the area. 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.
