@marekd, you are probably aware of it already, but I just wanted to point out that after your (unbelievable quick) fix, not only your gusts but also your other data is showing zeros after some time on the route...

Wow, that was fast. Thank you very much indeed!

@marekd and dear windy developers

For me it seems like your "speed option" is not really working. Windy (still?) behaves likes the vessel speed is infinite, meaning it is calculating the weather along the route with the forecast at the route start time. See the two screenshots. First one is the wind map at the start of the route. Second is the wind map during the route at route point #2: the weather at the current location on the map is very different from the route view.

It is also obvious by changing the vessel speed (e.g. 1kt, 10kt, 100kt, 1000kt): the weather along the route never changes.
