Thanks @idefix37 , that explains it!

In the Stockholm archipelago you really do not have the possibility to choose long legs, there are thousands of islands and many times more shallows and rocks. So you plan your route according to where it is possible to sail. If I then use Windy with setting left to right I will know if I need to tack or not. Which you for many reasons want to avoid and thus try to replan you route.

As I understand it north up does not give me that information, or? Bottom to top will but I think it is more intuitive to think of my complete route as a line left to right and I will see the relative wind on all legs.

Hi
I'm new to Windy but already loves it and especially route planning. I thought I had cracked the thing with the setting of wind bars direction (north up, etc) which is great. However when testing I noticed one strange thing I can not understand.
I get how the direction arrows swaps up to WP 5, but after that why is it not indicated that I will take the wind almost head on from portside, like my painted arrow?

Thanks for a truly great app!
