Emergency Messages

And Distress Procedure

VHF Marine Radio Protocols

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 “Illinois 1234 AB” three (3) times]

“Mayday Corsair (or Illinois 1234 AB)”

“Navy Pier bears 220 degrees magnetic — distance five (5) miles”

“Struck submerged object and flooding — need pump and tow”

“Four adults, three children aboard — no one injured”

“Estimate we will remain afloat one-half (1⁄2) hour”

“Corsair (or Illinois 1234 AB) is 26 foot sloop with blue hull and tan deck house”

“I will be listening on Channel 16”

“This is Corsair (or Illinois 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

•

Once your radio is connected to a GPS device and is properly set-up with your MMSI, simply lifting the red spring-loaded door and pressing the button will automatically send a complete distress call on Channel 70. See the DSC operation section on pages 56 through 69 for further information and page 57 instruction on sending a manual DSC distress call.
