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.

Official note of NOAA National Oceanic and Admspheric Agency USA:

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 human interpretation.

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.
