What is the correct sequence for using a VHF radio to call for help in an emergency?

• A. Call on Channel 16, identify your vessel, clearly state Mayday/Pan-Pan and position, then switch to a working channel for further communication.
• B. Use any available channel to broadcast your emergency as soon as possible and then switch to Channel 70.
• C. Call on Channel 16, then wait for a response before identifying yourself or stating the situation.
• D. Immediately switch to a working channel and broadcast your vessel name only, then call Mayday.

Answer: (A)

When you’re in an emergency at sea, you want to get attention quickly and provide essential details right away. The standard sequence is to hail on Channel 16—the universal distress and calling channel—identify your vessel, clearly declare the type of distress (Mayday for imminent danger or Pan-Pan for urgent but not immediately dangerous), and give your position. After that initial call, you switch to a working channel to carry on the conversation and relay more information as responders come on scene. Channel 16 is monitored by coast guards and nearby vessels, so making your initial, concise distress call there ensures the fastest possible alert and a response. Identifying your vessel and indicating your location and the nature of the emergency right away lets rescuers know who you are, where you are, and what kind of help is needed, without delay. Then you move to a working channel to provide details, coordinate with responders, and exchange instructions or updates. Other options don’t fit because they skip or weaken this sequence: broadcasting on a non-emergency channel or using Channel 70 for voice remains outside the intended distress procedure (Channel 70 is primarily for DSC). Waiting to identify yourself or stating the situation after a response delays aid. Trying to start on a working channel with only the vessel name, or failing to declare the Mayday/Pan-Pan, also leaves responders without critical initial information.
