Why
your VHF radio is Sooooo Important!
And why knowing how to use it, is more important!

 On
11 May 1993, two vessels that were in the same general area (the waters off Fan
Island, Porcher Peninsula, British Columbia.) transmitted MAYDAY messages at
about the same time.
The message, as received, read: "MAYDAY MAYDAY ... going down." The other
message read: "MAYDAY MAYDAY we're going down."
Due to the proximity of the vessels, and the almost identical messages issued,
both vessels were lost. The messages were transmitted on their VHF radios.
However, the procedures used during the transmission of the message and the fact
that they occurred almost simultaneously were the main reasons cited why the
Canadian Coast Guard response was prematurely terminated. [Transportation
Safety Board of Canada report]
This is an example, that highlights what can happen, when not properly using
your safety equipment. This error caused one of the crew to die from, and the
other crew members to suffer hypothermia. All because they didn’t follow tried
and tested emergency radio procedures.
All recreational boats should carry a VHF marine radio on board. While currently
not a federal regulation, the Coast Guard Auxiliary, during their Vessel Safety
Check (VSC) recommends this piece of safety equipment. More importantly, all
members of the crew need to know how to use this important piece of safety
equipment!
VHF Radio vs. Cell phone vs. Citizen’s Band (CB) Radio
A marine radio (VHF) can be bought as a handheld radio or a base unit.
Fixed mount (base) units can broadcast at a maximum of 25 watts, with the
ability of also being able to reduce power to 1 watt. Handhelds normally don’t
broadcast over 5 watts. Base units, given the correct tuning, height of antenna
and atmospheric conditions, can broadcast up to 20 nautical miles, but normally
in the 5-10 mile category.
Handheld radios have the advantage of being able to be carried while you move
around your vessel or while on a dinghy. The disadvantage of this type of radio
is the limited power (wattage per channel) that they are able to produce. The
smaller the wattage, the weaker the signal becomes as it radiates from the
antenna. Thus, the strength, and limited antenna size, makes long distance
communication nearly impossible.
Cell phones have large number of disadvantages, starting with the inability of
other mariner’s to hear your call for distress, which may not be heard by a
Coast Guard Units to the inability of the Coast Guard to use direction finding
equipment to hone in on your signal, should you be unable to describe your
location. Add to these factors the limited distances cell service extends into
the ocean, and you have a generally unreliable service.
Citizen Band Radio, the rage in the early to mid 1970’s, is for most intents and
purposes useless as a vehicle with which to contact the Coast Guard. Most Coast
Guard Units do not have them, and thus are unable to receive CB radio
broadcasts, and thus are not able to respond.
The safety conscious recreational boater will purchase the best safety equipment
they can afford, and when it comes to a VHF marine radio they will buy a radio
which will provide quality transmission signal strength, and the ability to
quickly listen and transmit on channels reserved for distress calls. In
addition, most new units have the ability to continuously monitor multiple
frequencies.
What to do in an emergency
Let’s briefly go over the three main types of emergency calls you will hear,
according to the Office of Boating Safety (OBS) of the United States Coast
Guard, while monitoring CH16 on your VHF radio:
MAYDAY is a
request for immediate assistance.
LISTEN! DO NOT TRANSMIT!! Determine if you're in a position to help. If not,
maintain radio silence. "MAYDAY" identifies an imminent, life-threatening
emergency.
PAN-PAN (pronounced pahn-pahn) is used when
the safety of a boat or person is in jeopardy. Man-overboard messages are sent
with the PAN-PAN signal.
SECURITÉ (pronounced say-cure-e-tay) is used
to pass navigation information or weather warnings.
According to the OBS, if you have an emergency, you should use your VHF radio in
the following manner:
If you have an imminent life threatening
emergency, transmit on Channel 16:
1. MAYDAY, MAYDAY, MAYDAY!
2. This is (name of boat three times).
3. Repeat once more, "MAYDAY", (your boat's name).
4. Now report your position (give as accurate a position as possible).
5. Report nature of emergency.
6. Report the kind of assistance desired.
7. Report number of people on board and condition of any injured.
8. Description of the boat and seaworthiness.
**Then wait for a response. If there is none,
repeat the message**
So, if your vessel is named Blue Duck and you
have an emergency, your broadcast may sound like this:
“Mayday-Mayday-Mayday
This Is Blue Duck - Blue Duck - Blue Duck
Cape Henry Light Bears 185 Degrees Magnetic-Distance 2 Miles
Struck Submerged Object
Need Pumps-Medical Assistance And Tow
Three Adults, Two Children Onboard
One Person Compound Fracture Of Arm
Estimate Can Remain Afloat Two Hours
Blue Duck Is Thirty Two Foot Cabin Cruiser-White Hull-Blue Deck House
Over”
Boating and Safety Education
In Canada, the responsibility for managing VHF
radio licencing has been given to the Canadian
Power & Sail Squadrons, although various other organizations and individual
examiners also offer training and testing. The CPS manual “Radio
Talk” is now the only authorized training material. Any individual operating
a VHF radio must hold a Restricted Operator Certificate (Maritime).
The United States Coast Guard, the Office for
Boating Safety and the United States Coast Guard Auxiliary are committed to
making Recreational Boating SAFE!
To this end, the USCG Auxiliary provides boating
and safety programs to meet the needs of our constituents, the boating public.
We do this by teaching a myriad of safe boating courses, available year-round at
convenient places to where boaters live, work and boat.
We provide Vessel Safety Checks at marina’s,
docks, and other centrally located areas. We want you to know that your vessel
not only complies with Federal standards, but with State and Local ordinances,
and with the other recommended safety items, we in the Auxiliary feel are
necessary to keep your boating voyage, safe.
In addition, members of the Auxiliary, who are
all volunteers, spend countless hours doing safety patrols, search and rescue
and homeland security patrols, on the ground, on the water and in the air.
To contact your local Coast Guard Auxiliary
Flotilla, you can either visit us on the web (http://www.cgaux.org) or contact
your local Coast Guard Unit (http://www.uscg.mil).
