VHF Marine Radio Protocols

“Mayday — Mayday — Mayday”

“This is Corsair — Corsair — Corsair” [or “IL 1234 AB,” repeated three (3) times] “Mayday Corsair (or IL 1234 AB)”

“Navy Pier bears 220 degrees magnetic — distance 5 miles” “Struck submerged object and flooding — need pump and tow” “Four (4) adults, three (3) children aboard — no one injured” “Estimate we will remain afloat one-half hour”

“Corsair (or IL 1234 AB) is 26 ft sloop with blue hull and tan deck house” “I will be listening on Channel 16”

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.
