Emergency Messages And Distress Procedure 
•
The ability to summon assistance in an emergency is the primary reason  
to have a VHF marine radio. The marine environment can be unforgiving,  
and what may initially be a minor problem can rapidly develop into a  
situation beyond your control.
The Coast Guard monitors Channel 16, responds to all distress calls, and coordinates 
all search and rescue efforts. Depending on the availability of other capable vessels or 
commercial assistance operators in your vicinity, Coast Guard or Coast Guard Auxiliary 
craft may be dispatched.
In an event, do not communicate with the Coast Guard as soon as you experience 
difficulties or before your situation becomes an emergency. Use the emergency 
(Distress) message procedures only after your situation has become grave or you are 
faced with a sudden danger threatening life or property and requiring immediate help.  
Use channel 16 to communicate your emergency message. Make sure you transmit 
on high power. If you are merely out of gas, do not send an emergency distress 
message. Drop your anchor and call a friend or local marina to bring the fuel you need 
or to give you a tow.
Marine Emergency Signals
The three (3) spoken international emergency signals are:
The distress signal MAYDAY is used to indicate that a station is threatened  
by grave and imminent danger and requests immediate assistance.
The urgency signal PAN is used when the safety of the vessel or person  
is in jeopardy. (This signal is properly pronounced pahn.)
The safety signal SECURITE is used for messages about the safety of navigation or 
important weather warnings. (This signal is properly pronounced see-cure-it-tay.)
When using an international emergency signal, the appropriate  
signal is to be spoken three (3) times prior to the message.
If You Hear A Distress Call
You must give any message beginning with one (1) of these signals priority  
over any other messages. ALL stations MUST remain silent on Channel 16  
for the duration of the emergency unless the message relates directly to  
the emergency.
If you hear a distress message from a vessel, stand by your radio. If it is  
not answered, YOU should answer. If the distressed vessel is not nearby,  
wait a short time for others who may be closer to acknowledge. Even if  
you cannot render direct assistance, you may be in a position to relay  
the message.
