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”

“This is Corsair (or IL 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.
