What I dont understand in Alexrider video is that he has the depower line depower at aproximately 40%-60%. At his weight, it is almost impossible that the wind is only 10 knots using all that depower. His jump would have been quite higher if he had remove the depower to power and edge more to hold more power.
(P.S, I really, really enjoy riding overpower.)
I cannot remember how old was the kite when the video was made. For normal riding I trim so that when at the zenith, the kite just starts to stall. If it was trimmed as much, it could have been because the front lines had stretched.
During the ride I usually trim to full power (high angle of attack) for downwind carving (or wave), or jumping, as you suggest. High aspect ratio foils normally turn with a large radius, so to compensate for that and keep it low in a jibe, I get it to stall or nearly stall, which doesn't happen with the stock kite as originally tuned. In order to allow that, I lengthen the little black chord above the trim system. That explains why the trim is pulled halfway in normal conditions.
When going upwind however, I trim to the lowest possible angle of attack just before the kite changes its shape.
I believe what I said. FS + Mako Wide is a combo that goes amazingly well upwind and consequently generates considerable apparent wind on flat water. I think all FS riders know that
If no LEI were seen on the water on the Sanur break (which I think was the case), the wind was not more than 10 knots for sure!
