VHF Marine Radio Protocols
Emergency Messages and
Distress Procedure
Marine Distress Procedure
Speak slowly — clearly — calmly .
1.
Make sure your radio is On .
2.
Select Channel 16 .
3. Press Talk button and say:
“MAYDAY — MAYDAY — MAYDAY .”
(Or “PAN — PAN — PAN,”
or “SECURITE — SECURITE — SECURITE .”)
4. Say:
“THIS IS [your vessel name or call sign],” repeated three (3) times .
5. Say:
“MAYDAY (or “PAN” or “SECURITE”)
[your vessel name or call sign] .
6. Tell where you are:
(what navigational aids or landmarks are nearby) .
7.
State the nature of your distress .
8.
State the kind of assistance needed .
9.
Give number of persons aboard and conditions of any injured .
10.
Estimate present seaworthiness of your vessel .
11.
Briefly describe your vessel (length, type, color, hull) .
12. Say:
“I WILL BE LISTENING ON CHANNEL 16 .”
13. End message by saying:
“THIS IS [your vessel name or call sign] . OVER .”
14.
Release
Talk
button and listen . Someone should answer .
If not, repeat the call, beginning at step 3 above .
Keep the radio nearby . Even after your message has been received, the Coast Guard
can find you more quickly if you can transmit a signal for a rescue boat to hone in on .
For Example
“Mayday — Mayday — Mayday”
“This is Corsair — Corsair — Corsair” [or “IL 1234 AB”
“Mayday Corsair (or IL 1234 AB)”
“Navy Pier bears 220 degrees magnetic — distance 5 miles”
“Struck submerged object and flooding — need pump and tow”
“Four (4) adults, three (3) children aboard — no one injured”
“Estimate we will remain afloat one-half hour”
“Corsair (or IL 1234 AB) is 26 ft sloop with blue hull and tan deck house”
“I will be listening on Channel 16”
“This is Corsair (or IL 1234 AB)”
“Over”
It is a good idea to write out a script of the message form and post it where you
and others on your vessel can see it when an emergency message needs to be sent .
Marine Distress Procedure – DSC
•
Digital Selective Calling (DSC) is a semi-automated system that will allow you to press
the
Distress
button from any routine to make a distress call . When the distress button
is pressed, all other channels go to
Standby
mode and allow the digitally encoded “pre-
programmed” message to take precedence . Important information such as your MMSI
number, position and name will be transmitted on Channel 16 . The distress alarm will
sound for two (2) minutes or until the alarm is cleared .
The DSC system allows you to choose a “pre-programmed” distress call such as: “Man
Overboard, Sinking, Collision .” There are many pre-programmed choices to choose from .
If a GPS is connected to your radio, your coordinates will also be sent to the Coast Guard
as well as to other vessels that are within range of the transmission . DSC calling also
allows the user to initiate and receive distress, urgent, safety, routine, position request,
position send and group calls between vessels equipped with DSC capable radios .
WARNING
This radio will generate a digital maritime distress and safety signal to help
facilitate search and rescue . This radio must be used only within communication
range of a shore based VHF station with a distress and safety watch system . The
range of the signal may vary .
