Then repeat once: "
Mayday
, XXXXX" (your vessel's name).
3.
Report your position in latitude/longitude, or give a true or magnetic bearing (state
which) to a well-known landmark such as a navigation aid or geographic feature
such as an island or harbor entry.

Explain the nature of your distress (sinking, collision, aground, fire, piracy, life-
threatening injury, etc.).
5.
State the kind of assistance you desire (pumps, medical aid, etc.).
6.
Report the number of persons aboard and condition of any injured.
7.
Estimate the present seaworthiness and condition of your vessel.

How to Call Another Vessel (CH16 or CH9)
CH16 (or CH9, depending on area) should be used as the calling channel for initial
contact with another vessel. However, its primary purpose is for emergency commu-
nications and should be monitored at all times when not using other channels.
It is monitored by Coast Guard stations in all countries and other vessels.
The use of CH16 should be limited to making initial contact only. Calling should not
exceed one minute, but may be repeated at two-minute intervals.
Prior to making contact with another vessel, refer to the channel charts in the Appen-
dix and select an appropriate channel (working channel) for use after initial contact.
Monitor the proposed channel to ensure you won’t be interrupting other traffic and then
go back to CH16 to make your initial call.
When channel 16 is clear, state the name of the vessel you wish to call and then "
this
is
" followed by the name of your vessel and your vessel callsign. When the other ves-
sel returns your call, immediately request another channel by saying "
