Is there a difference in distress signal procedures for boats vs. land?

Distress Signal Procedures for Boats

Boats in distress use the International Distress Signal, three short blasts on the horn, followed by a minute of silence, repeated three times. This signal can be heard by other vessels or coastal stations. For emergency situations where a radio is not available, a mirror or flares can be used to signal for help.

Distress Signal Procedures for Land

On land, a whistle or other loud noise-making device is used to signal for help. Three short blasts on a whistle are the standard signal for distress, followed by a minute of silence, repeated three times. It’s essential to know the location and use landmarks to guide rescuers.

Using a Signal Radio for Distress Calls

When using a signal radio for a distress call, follow the Mayday procedure: “Mayday, Mayday, Mayday” followed by your name, location, and nature of the emergency. This procedure is used for life-threatening emergencies, while a Pan-Pan call is used for less urgent situations. The Mayday call is transmitted three times, with no pause between the calls.
