The WR module tries to find the track that is closer to the destination
at a given time (great circle distance). Isochrones will show the sets
of points that can be reached at that time. The isochrone label marks
the best point for the isochrone. Sometimes the best track for days
ahead passes thru low boatspeed areas (this is the fun of the game)
Proximity of land is
not covered at this time.
This weather routing calculator does not see any land
Need to add that to the wishlist...
