VHF Marine Radio Procedures
•
Maintain Your Watch
Whenever your boat is underway, the radio must be turned On and
be tuned to Channel 16, except when being used for messages.
Power
Try 1 watt first if the station being called is within a few miles. Try a second call
after waiting two (2) minutes. If there is no answer, switch to a higher power. This
will conserve your battery and minimize interference to other users by avoiding
repeated calls.
Calling Coast Stations
Call a coast station on its assigned channel. You may use Channel 16
when you do not know the assigned channel.
Calling Other Vessels
Call other vessels on Channel 16 or on Channel 9. (Channel 9 is preferred
for recreational vessel use.) You may also call on ship-to-ship channels
when you know that the vessel is listening on a ship-to-ship channel.
Initial Calling on Channel 16 or 9
The use of Channel 16 is permitted for making initial contact (hailing) with another
vessel. The limits on calling must be followed. Be reminded, Channel 16’s most
important function is for Emergency Messages. If, for some reason, Channel 16 is
congested, the use of Channel 9, especially in U.S. waters, may be used as the initial
contact (hailing) channel for non-emergency communication.
