Hundreds of vessels move in and out of ports,
bays and waterways around Australia each day
like a symphony.
The code that makes this aquatic orchestra
work so seamlessly is the understanding of marine radio.
Whether a sea kayak, runabout, ferry or cruise liner,
it's only when everyone understands
and uses the right channels and protocols
that it can all work together.
Welcome to ACMA TV, and today we're going to visit
some of Sydney's best boating locations
to hear from the experts about marine radio.
Even the best prepared boaters can run into problems
and that's why it's important to not only have
but know how to use your VHF radio.
That's exactly right. Now, there are two main types of marine radio
for non-commercial vessels. They are marine VHF and 27meg.
VHF is now the predominant form of communication on the water
because the networks of base and repeater stations
available around Australia.
VHF radios have much better coverage, range,
not to mention less interference than the older 27meg radios.
In every state in Australia
there are dedicated teams of marine rescue workers
from volunteers to police.
These teams work around the clock
to ensure the safety of recreational boat owners
and commercial vessels.
We are here at one of Australia's oldest
and most iconic signaling stations, South Head, in Sydney.
So Greg, how important is it to use VHF radio
when we're out on the water?
It's very important to use VHF radio when you're out on the water.
It's for your safety.
You should do a radio check before you go out.
You should listen for weather and warnings.
Priority warnings are broadcast immediately,
routine forecasts generally every two hours for marine rescue.
You should listen in case there's a call for help on VHF 16,
and if you get into trouble call for help on VHF channel 16.
Earlier this year while on a typical fishing expedition,
Peter was called out when a strong southerly wind picked up.
Knowing this part of the harbor well
Peter decided it was best to find a more sheltered spot to fish
until the wind died down.
When Peter's normally trusty engine suddenly stopped,
he found himself drifting steadily toward the rocks.
Peter decides to call for immediate assistance
on VHF radio emergency channel 16.
Mayday, mayday, mayday.
This is Pete's Boat, Pete's Boat, Pete's Boat.
Mayday, Pete's Boat.
Inside North Head at Old Man's Hat
about 100 metres from the rocks.
Strong wind blowing me towards the rocks.
Engine has died and won't start.
Two persons on board. Five meter silver runabout.
I need immediate help, over.
At South Head one operator takes down all the details
while the other places a call to the water police
and the nearest rescue boat. Marine Rescue radios back to Peter.
Mayday Pete's Boat, Pete's Boat, Pete's Boat.
This is Marine Rescue Port Jackson,
Marine Rescue Port Jackson, Marine Rescue Port Jackson,
received mayday. Confirming your position
at Old Man's Hat, 100 metres from the rocks
and two people on board.
Please make sure you have the life jackets on
and put out your anchor. Rescue vessels are nearby
and will be there as soon as possible.
Stay on this channel, over.
Peter replies, still on the emergency channel 16.
Mayday, Marine Rescue this is Pete's Boat, Pete's Boat.
Position and persons on board correct, I will put out the anchor, over.
Marine Rescue Port Jackson,
having now spotted the distressed vessel through the binoculars
to confirm the position
puts out a call to all nearby vessels.
Mayday relay, mayday relay, mayday relay,
all ships near North Head, all ships near North Head,
this is Marine Rescue Port Jackson, Marine Rescue Port Jackson.
Mayday relay Pete's Boat, silver, five metre runabout
is being blown toward the rocks at Old Man's Hat.
Position south 33 degrees, 49.3, east 151 degrees, 15.4.
Two people on board.
Any vessel able to assist please call marine rescue Port Jackson
on this channel and advise your position
and the assistance available, over.
Meanwhile the Water Police and a Marine Rescue vessel
have been dispatched at high speed.
Pete's boat, this is Marine Rescue Middle Harbour 3-0.
We have received your mayday
and are proceeding to your location at all haste, out.
So Greg, in short what is correct operational procedure
when it comes to making an emergency call?
The correct procedure for making an emergency call
is to change to channel 16, call mayday, mayday, mayday,
and the name of your vessel three times,
give your position, describe the problem,
how many people on board, describe the vessel,
local conditions and what you're planning to do.
Leave your radio switched on and tuned to channel 16.
This is so you can hear and respond to any distress calls.
Always call on channel 16, then switch to a working channel.
Use channel 72, 73 or 77 to call and work with other vessels.
Use channel 73 to call and work with a coast station,
and when finished, resume listening on channel 16.
Remember your manners and no swearing.
Be accurate, brief and clear.
Greg why is it important to have good microphone technique?
It is important to have good microphone technique
to convey your message clearly.
Put your thumb on your cheek and speak across the microphone
with a steady rhythm to avoid any distortion.
Now, what are the things you know to think about
with your marine radio,
things you can check before you go out to sea?
Okay, the three main things that you want to check
before you head out to sea.
The first one will be the radio unit itself and the handset.
So obviously you want to make sure it turns on,
all your channels are lighting up so you can highlight your channels.
You also want to make sure,
a lot of boats are exposed to salt spray, things like that
when they're out so they can corrode,
they can get a little salt buildup, things like that,
so you want to make sure when you're finished for the day
you clean it off so next time it will be free of corrosion.
Second one is your aerial. You want to make sure
that it's actually attached to your boat.
People take them off for storage, put them in garages,
things like that, so make sure your aerial is on,
it's attached, it's elevated, free of any obstruction.
And the other thing about aerials,
they can become flaky from UV, sun effects,
things like that, salt,
so you want to make sure it's not flaky or crumbly,
it's in good condition. And lastly your battery.
You want to make sure that it's fully charged
because obviously the radio is not going to work
without a charged battery.
Some people like to have a separate battery bank
purely for their radios as an extra safety consideration.
They believe that if everything else fails,
your electronics, that's fine.
You've got the extra battery there purely for your radio
for that emergency situation if it arises.
Thanks for watching ACMA TV.
Now remember next time you're on the water,
use your marine radio to log on with local rescue services.
And jump on the ACMA website for your copy of the VHF handbook.
