Hello maitai,
Perfect job.
For testing, i created a wind independed polar (eg on all twa/tws 5kn). The first routing only with windgrib (blue) and then loaded a courrentgrib and did a second routing with the same settings (red)to see the influence of the tidalstream.

Very nice! Thanks Maitai and hwecken for showing how its done.

I'm still a little unclear, correct me if I'm wrong-

Simply load two GRIBs consecutively, 1 wind and 1 current and do a routing!

Apparently 2 different Gribs will be stacked whereas with 2 similar Gribs the second will replace the first?

Last Jan. I sailed from keywest to Isla Mujeres. This would have been really useful.

The second grib loads only currents data. That is, if it contains something else this something else is ignored, only currents data is loaded. If the first grib contains currents data (i.e. it contains winds + currents) then the second grib currents data is ignored.
