The wind was approx 20-30 SSW
Hardie has found a straight line Nm which has a nice consistent bear away over the full run of about 2km, it's a bit softer angle than the straight speed run but more consistent over the distance.
The wind angle can change a bit as we don't have to run next to a sand bank, ours is open water weed flats, so you can pretty much pick your spot to attack when you see the gust coming.
The down side's we have is that you have to use weed fins, the waters shallow (some guys were depth checking

with 30cm fins), for the uninitiated it can be a bit daunting blasting along seeing fin trails through the weed banks.
