Letter from David, KD6DOR

20 February 2011 | Storms River
Dear Graham.
Thanks for your help.

Imagine the following scenario; as dawn breaks on the seventh day of an ocean
crossing passage, the sky is full of ominous black clouds, the swell has
noticeably increased overnight and the barometer is in free-fall. There is
definitely stormy weather around but where and how to minimize its effect. You
are beyond the coverage on normal weather transmissions but there are a group
of dedicated radio operators ready to help you. At 0730UTC the HF radio is
tuned to 14316Hz and a faint voice is heard but in a few minutes the magic
words 'Swinging the beam round to the Atlantic' clearly comes through above
the static. It is Graham, the net controller, of the South African Maritime
Mobile Net with the latest weather information.

Every day at 0730UTC the crew of the yacht 'Toucan' eagerly gather around the
navigation area to listen to the net. We make our position report in the
role-call of yachts on passage, noting the locations given by others that are
nearby. It is very re-assuring to know that there are others in the vicinity,
although out of sight but contactable if the need arises. Sometimes, after the
net, we talk to other yachts, so the net acts as a focal point for yachts
making similar passages. The weather information is copied and decisions are
made about which course to steer based on the weather input. In our last
passage from St Helena to Brazil the weather was quite benign and basically we
only had to decide to gybe onto port or starboard tack if the wind was
forecasted to back or veer. But, in other passages, in other oceans and with
other Ham nets, we have been faced with the scenario outlined in the

Disseminating weather information is just one aspect the net controllers job,
the capturing the daily position of net participants ensures that the SAR
authorities have a good idea of the probable position of a vessel is if an
emergency arises. Not all problems require such drastic action. In may cases a
minor malfunction of some part of a yacht's system can negatively impact life
onboard. Information as to the probable cause and rectification can be obtained
from the manufacturers by the net controller and relayed during the next

In all, Ham radio maritime nets provide the help and assistance to all
sailors leading to safer and more stress-free passages.

Kind regards

Yacht 'Toucan'
