utes until distress acknowledgment is received.

main VHF DSC.
MAYDAY PROCEDURE
When DSC distress acknowledgement is received after you pushed
DISTRESS, or if you otherwise need to commence distress traffic by
radiotelephony on the distress traffic frequency channel 16, this should
follow:
• “MAYDAY”,
• “this is”,
• the 9-digit identity
and
the call sign or other identification of the ship,
• the ship’s position in latitude and longitude or other reference to a
known geographical location,
• the nature of distress and assistance wanted,
• any other information which might facilitate the rescue.
Upon reception of a DSC distress alert from another ship in distress, you
should acknowledge the receipt by radiotelephony on the distress traffic
frequency channel 16, with the following:
• “MAYDAY”,
• the 9-digit identity of the ship in distress, repeated 3 times,
“this is”,
• the 9-digit identity or the call sign or other identification of own ship,
repeated 3 times,
• “RECEIVED MAYDAY”.
