Group MMSI as yours.

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
x
status, and any course corrections.
A power boat full of spectators comes too close to the race path. You use individual
x
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
x
communicate with the rowboat. You use all ships calling to alert all the other ships in
the area of the possible danger.
