    Euronav Ltd is not in anyway recommending or supplying any of the above services. Using any of the services is at your own risk and cost. 

    Please remember a forecast is just one possible prediction of the future weather pattern. Longer range  forecasts will be considerably less reliable than short range forecasts. Some of the data is fairly 'broad stroke' and will not take into account local conditions.

    Which one is best ?
    This all depends if you wish to pay, the cost of your communications, and the amount of detail and data types you need.

    Free data:
    seaPro Weather routing - for this you only need wind information, for worldwide coverage  try  Global Marine Networks (compressed files - shorter download))

    Purchased data
    GRIB data from  Meto France or the Norwegian weather service (Europe only) offer a more comprehensive service including  sea temperatures, wave heights, currents, smaller cells sizes etc.
    These data sets tend to cover the needs of commercial applications such as fishing.

    To use the data you should:- 
    Download the GRIB data from a weather site (above web sites)
    Download the file to your seaPro grib file folder (typically C:\program files\euronav\seaPro2000\grib)

    If the GRIB file has been zipped you will need to unzip it. - download a copy of the WinZip utility from any number of sites  (this is usually shareware)
    If bz2 , seaPro will automatically decompress the files for you

    To use the file, open seaPro (if not already running), select "weather" and the "weather (GRIB) from the menu.This will then allow you to pick the GRIB file you wish to view.
