VHF Radio Emergency Calling Procedures

Note: Emergency-related calls always have priority over routine messages.

  1. Turn on your VHF radio. Select Channel 16 (the primary hailing and distress frequency) or Channel 9 (the backup frequency).
  2. Set the squelch so you don’t hear any static or “white noise.” 
  3. Listen for 30 seconds (or more) to ensure there’s not a conversation in progress. 
  4. If the channel is clear, push the “Talk” or “Transmit” button. 
  5. State the name of the boat (or marine resource) you’re calling. Repeat that name 2-3 times. Next, state your boat name.
  6. If you don’t receive a response, keep trying until you get one.
  7. When you make contact, provide all details about the emergency. 
  8. For a “Mayday” call, state the type of emergency and the type of assistance you need. State the condition of the boat, along with the number and condition of the people on board.
