With Joel banging on about upwind tacks on the buggies, he's got me started to see if I can do them kite surfing. I mostly ride with a uni-directional board and have seen upwind tacks done on course racing vids. I have tried a few times and usually run out of speed and come to a stop before completing the turn or end up doing and upside down superman as the kite goes into the power zone. To try and get the hang of it, I have also started to try this on the landboard.
Did not see much on the web until I realised they have another name for it, a duck tack.
Here are some instructional videos I found.
So please share your tips and experiences trying this upwind tack.
