hei there
I tried to search for this in the forum, but couldn't find.
As I see it,
- the wind forecasts deliver GROUND WIND (GWS, GWD).
- This wind forecast is input into the optimal route calculations.

When adding current/tide into the optimal route calculations, does the algorithms then add the effect the current/tide has on the TWD/TWS? so that the for example the TWA given in the optimal route results, is based on GW+CURRENT? Or is the current only included as an effect on SOG and COURSE?

was this clear??

best regards
