If you are in imminent and grave danger at sea and require 
emergency assistance, use VHF Channel 16 to send a distress 
call to nearby vessels and the United States Coast Guard. 
Transmit the following information, in this order:

“MAYDAY, MAYDAY, MAYDAY.”

“THIS IS _____________________, CALL SIGN 
__________.”
State the name of the vessel in distress 3 times, followed 
by the call sign or other identification of the vessel, stated 3 
times.

Repeat “MAYDAY” and the name of the vessel.

“WE ARE LOCATED AT _______________________.” 
State the position of the vessel in distress, using any 
information that will help responders to locate you, e.g.:
• latitude and longitude
• bearing (state whether you are using true or magnetic 
north)
• distance to a well-known landmark
• vessel course, speed or destination

State the nature of the distress.

Specify what kind of assistance you need.

State the number of persons on board and the number 
needing medical attention, if any.

Mention any other information that would be helpful to 
responders, such as type of vessel, vessel length and/or 
tonnage, hull color, etc.

“OVER.”

10 Wait for a response.
11 If you do not receive an immediate response, remain by the 

radio and repeat the transmission at intervals until you 
receive a response. Be prepared to follow any instructions 
given to you.

For non-commercial transmissions, such as fishing reports, 
rendezvous arrangements, repair scheduling, or berthing 
information, use VHF Channel 9.
