May Day Realy is used 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).

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 Mayday Relay Call and Message.

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.
