Mayday Relay

This is when you know of someone else is in distress but they are either unable or have no means of contacting a coordination centre (probability the coastguard).

Relay Immediately

If the vessel or person has no means of transmitting a distress you can transmit on their behalf immediate ie. a person stranded by the tide or if you see a set of distress flares.

Relay after 4 Minutes

For vessels who have sent a Distress alert and/or call but not received an acknowledgement from a Ship or Rescue Co-ordination centre.

In these situations we could consider sending a Urgency alert followed by a Mayday Relay Call and Message. The sheet below highlights the procure step-by-step.

Mayday Relay Message

LEARN: Before the course, make sure you know the basic structure a Mayday relay call and message.

Note: No digital alert or announcements should be sent before transmitting by vioce (this was changed in 2019). 

If you are relaying a message you may not know all the details you would normally include in a mayday message. Don’t guess. Simply do you best to transmit the important information. ie. if you message is on behalf of a person stranded by the tide, give their position but will not have a callsign or MMSI number.

Example 1

In this situation you have received yacht “Tinky Winky’s” mayday which has not been acknowledged.

You noted down all the details and waited 4 minutes before deciding to transmit the following message. Note that the call includes your details (you are on yacht “Dipsy”) but the message is a carbon copy of Tinky Winky’s message.
