The XyGrib file reader provides this.

The point is, inReach pulls this data from gribs. So you would get into the same challenge with a large area grib and MaxSea or any other software.


BTW it is interesting that you got more weather than forecast. The same thing happened to us on our latest passage to the Azores. In result, we never made Azores. We were offered the option of sailing non-stop from Caribbean to Canary Islands. Something I always dreamt about and I am happy to know how it feels (so I do not feel tempted to do it again).



As a weather router, I have faced this problem many times (most recently last week on passage from Gibraltar to Canary Islands).


It is as if the models underestimated the wind force in many areas, and not just where the sea and land interplay but also where the water is open (e.g. passage from ABC to Mona).
