Setting to North up seems to have cured this, stupidly I didn't look at what it had been set to but guessing it was something else. Hadn't noticed this option, thanks.

@roohairy Have been playing with this more, this bug seems to only be associated with routes through #Marco. Later on into #Laura wind directions are good along a route.

I have noticed today that wind and wave direction along a route are approx 90 degrees out. They are shown correctly in a forcast for a given location, but along a route are incorrect. In the image legs 2 - 3 winds are pretty much across the leg, easterly wind, but in data below are shown as northerly.
