A security message contains information associated with the safety of vessels at sea.
It is sometimes used by the coastguard to draw people’s attention to a new navigational warning or gale warning. In which case they will send a All Ships Safty Alert and then broadcast the message on a working channel.
In fact it is far more likely that the coastguard would make a security message than any other station. This is because if a vessel was to come across a situation which they wish to pass on to other vessels (a navigational mark breaking free, a shipping container floating below the surface etc…) it is better to pass this information to the coastguard for them to transmit. This is as they have a much greater range and can continue to warn vessels into the future.
The sheet below highlights the procure for sending a Safety Alert followed by a Securite message.
Simply this is the only situation when you send a safety alert.
On the Icom this is done by:
– Press MENU
– Scroll using the ARROWS to All Ships Call
– Press ENTER
– Scroll using the ARROWS to Safety
– Press ENTER
– Press ENTER again to confirm
– The Alert has been sent.
The alert is a digital message which includes your MMSI number but NOT your position.
If this does not make it clear, see the video below (DO NOT DO THIS ON A NORMAL RADIO):
Once the alert is sent you should wait approximate 10 seconds for the alert to be acknowledged and people to grab a pencil.
The alert is followed up by a verbal Securite call and message.
