The grib files are computer files which therefore have to
be downloaded with an internet connection. MeteoFax32 is a
system designed precisely to work without reliable
internet connection at sea. Downloading files at sea using
means such as satelite phone, email by ssb, etc. .. is
very uncertain and expensive. Systems using motorized
dishes are very expensive and can not be used at sea on
small boats because of the movement of the boat on rough
sea. The use of these methods of communication can not be
automated as required in difficult conditions of
navigation. It is unrealistic to expect to rely on this
type of connection to ensure the coverage of weather
forcast during a transatlantic sailing on a sailboat. On
the other hand the information contained in the grib files
are between 2 and 4 hours later compared to those provided
by radiofax which can be annoying to track a dangerous
phenomenon. You should also beware of readability without
comparison with the actual accuracy of the displayed data:
it is not because you view a wind vector every 5 miles
that a forecast calculation was done for all points. It
may be an interpolation between different points distant
of several hundred miles. You can download GRIB files to
your browser when you are at mooring (we recommend using StarNavPilot
that automatically download GRIB files) then you
switch to MeteoFax32 for an automatic and unattended
reception of weather charts at sea.

CAUTION: Internet is not part of the GMDSS system. You
should never rely on the internet as the only means of
obtaining weather and safety information at sea. Access
may be interrupted. Problems updating documents may also
occur. Use only official sources: radiofax, Inmasat
SafetyNet or NAVTEX for complete information.
NOTE: The weather forecasts are not really reliable after
of 96 hours (4 days). GRIB files are created only by
computers on the basis of forecast models. There is no
CAUTION: Never refer to grib files
for monitoring extreme events such as tropical cyclones.
Use the weather charts and documents specifically
dedicated that you can receive at sea with MeteoFax32.
