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.

Radiotelephone Calls

Radiotelephone Calls

Boaters may make and receive radiotelephone calls to and from any number on 

the telephone network by using the services of public coast stations. Calls can be 

made — for a fee — between your radio and telephones on land, sea, and in the air.

See pages 14 through 23 for the public correspondence (marine operator) channels.

If you plan to use these services, consider registering with the operator of the 

public coast station that you plan to work through. Those services can provide 

you with detailed information and procedures to follow.

CAUTION

You may disclose privileged information during a radiotelephone call. 

Keep in mind that your transmission is NOT private, as it is on a regular

telephone. Both sides of the conversation are being broadcast and can be

heard by anyone who has a radio and tunes to the channel you are using.

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 any event, do communicate with the Coast Guard as soon as you experience

difficulties and before your situation becomes an emergency. Use the emergency

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. 

If you are merely out of gas, do not send an emergency message. Drop your 

anchor and call a friend or marina to bring the fuel you need or give you a tow.
