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.

Wind / wave direction incorrect 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.
