MaxSea does weather routing. Info here:

The key to success is obviously ultra accurate polars and weather data not to mention some pretty heavy duty math on the part of the operating system and SW.
It's also very expensive.

That's just an updated version of the one that sent me and Jaga sailing up the Sierras... Even the old one needed good polars and grib files to work. Hope the current one is a bit smarter Actually, the new one looks very much as I recall from 5 years ago. I also recall it was very processor intensive and could take an hour or more (much more?) to calculate a lengthy routing. Of course 5 years ago that was on a processor with significantly less power than today's.
