Hope all is well in the Caribbean!
works as follows:
I inputed the polars from a Beneteau
375, I don't have a polar for your boat but figured this would be fairly close.
I downloaded todays grib file for the North Atlantic which is a 15 day grib. Obviously predicting the weather 15 days out is not very good. Fronts stall or speed up,,, you know. We have the ability to download files enroute so some of the time vagaries are minimized.
then calculates the best route based on the wind direction, wind speed, sea state, currents, and future weather conditions against the polars of the boat.
It will looks to see where the boat should sail for the best weather opportunity based on how the weather system moves and how fast the boat can sail. It is a predictive software using polars of an individual boat againts a changing weather picture. I hope I'm explaining it correctly?
Anyway, if you want I'll keep running it daily and to see what the average looks like. The grib being 15 days does not show a start to finish but shows you past the Azores in 15 days.
Have a rum
neat for me!
