Suppose you are coordinating safety for a sailboat race. Before the race starts, you instruct
all the racers to enter your group MMSI number into their radios. During the race:
• Throughout the race, you use
group calling to update the
racers on the time, race status,
and any course corrections.
• A power boat full of spectators
comes a little too close to the
race path. You use individual
calling to contact the power
boat and advise them to stay
clear of the race.
• You see a rowboat entering the
area, but since it doesn’t have
a radio, you can’t communicate
with the rowboat. You use all
ships calling to alert all the
other boats in the area of the
possible danger.
