Due to internal changes still in process from Sailing Weather Service, our comfortable way of displaying their GRIB files is no longer available. Some of their files appear to be damaged, displaying an error message about a bad section length. However, the files working you can still open in WeatherTrack. We changed the menu slightly and will guide you directly to their website. We will try to make this more comfortable again and will notify you about changes here, in the WeatherTrack News.
