DISTRESS CALL
A Distress call should be transmitted if, in the
opinion of the master, the ship or a person is
in distress and requires immediate assistance.
Note: Never use the Distress call when your ship
or a person is not in an emergency. A Distress
call should only be used when immediate help
is needed.
