To make a clear radio call to the Coast Guard, tune your marine VHF radio to Channel 16 (or Channel 9 for routine/non-emergency checks), listen to ensure the frequency is clear for 10 seconds, and state “[Coast Guard Station Name] three times, this is your boat name and call sign, over”. [1, 2]

Radio Calling Format

• Listen first: Check that the channel has no other traffic.
• The Hailing Call: Say the name of the Coast Guard station or group three times.
• Identification: Say “THIS IS” followed by your vessel’s name and official call sign (or registration number) once or three times depending on urgency.
• The Handover: End with “OVER” and release the mic button to listen. [1, 2, 3, 4, 5]

Standard Marine Broadcast Hierarchy

• MAYDAY (Life-Threatening): Use if you face grave and imminent danger requiring immediate assistance. Repeat “MAYDAY” three times.
• PAN-PAN (Urgent): Use for urgent safety situations where the vessel or crew is not in immediate peril (e.g., steering failure or a lost person). Repeat “PAN-PAN” three times.
• SECURITE (Navigational Safety): Use to broadcast important weather warnings or navigational hazards. [1, 2, 3, 4, 5]
