If you are sailing in the Mediterranean or anywhere else for that matter that is isolated from other oceans, you may be interested in using free (or subscription) weather forecast services from local weather services. These files come in the form of GRIB files just like the ones inside TIMEZERO. For local areas, sometimes it can be useful to get a local perspective on the weather. While TIMEZERO provides a highly accurate weather forecast service, it does so on a global scale and so it could be worth your while to compare the two.
