Hello Cvetan. First, thanks a lot for this excellent tool that zezo is.

Cliking on a dark point of my route, I saw in the white window these informations :


2020-07-21 00:30 CEST (T+1:00)
Wind : 7°
TWA : 36°
Heading : 39°

Programming in VR gives me
Wind 8°
TWA 36°
Heading 44°

Heading in Zezo might be 43° isn’t it ? Or I misunderstood?

TWA -36° of course

Zezo is sailing straight lines (albeit sometimes short 10-minute straight lines). A heading of 39 at the time you checked would have produced an average TWA over that time span of 36, because the wind was shifting.

I believe that explains why Zezo said 39 instead of 43. As far as why Zezo said 7 while VR said 8... there have been several other threads about differences in interpolation between Zezo and VR and VR's UI.

Thanks @YourMomSA. So need to check route several times during these particular moments.(7 vs 8 could also be explained by rounded numbers).

Post by iconPost by YourMomSA | 2020-07-21 | 23:21:19
Don't try to sail exactly what Zezo says. Instead, try to understand what Zezo is trying to do, and then sail whatever best approximates that in the game. In this case, Zezo was trying to sail optimal upwind VMG angles. So that's probably right regardless of the one degree difference. The one degree difference might, though, cause your ideal timing for a tack to change by a bit.

Thanks YourMomSA. I will try.
