One of the best teachers out there! Combining footages and technical details.

Would've preferred a video labeled the secret of not killing lines tension haha

Would've preferred he explained it correctly...

But nice to see some measurements.

Mobile, so not in the mood for long texts. First of all...kinda funny that I have to elaborate, but Anton does not. Second, I already explained some things in the past. Nobody cared.

Short version: Tension is an effect, not a cause. The lift/tension diagram is wrong, doesn't take drag into account and ignores that the tension vector can be seen from the riders side too. He also seems to regard the window as a static thing (also in his other videos), which it is not the case, plus bringing the kite to the edge to lose power doesn't sound to logical when you have to edge hard to build tension and jump high, now does it? Also the LE pinching is a result from changing absolute and relative aoa in combination with the bridle shape, not from simply more power, and it certainly doesn't catapults you (the lines don't either btw)

But as I said, it's nice to see some actual force values acting on the hook.

It's more risky to just assume the first person that's trying to explain something is right.

He knows his techniques but he doesn't know all his theory.

Yes Faxie is correct. Kite lines or kite itself isn't any kind of bungee system in which you load energy and then release it for a jump.

Real explanation is about force and counter force, about your ability to edge and take the force kite offers in your harness and finally to the water. That is the counter force for your kite. That force is the limiting factor for how high you can jump and even more than that: if you can hold more power kite will give you even more power because it will accelerate and generate even more lift.

Another factor or another point o view is the kinetic energy kiter has. Having more speed enables of course higher jumps but high riding speed has to be converted to high force to the harness, high line tension.

If your kite is powered up it can develop huge amounts of lift if counter force is not limiting it. Simple example is if you attach your chicken loop to a fixed point and drive kite through the WW and sheet in at maximum speed. Kite may rip itself apart or break the lines, it generates that much lift. Another dangerous/foolish example is to have a guy holding you at the back of the harness when launching the kite. Then you almost double the counter force and therefore possibly the lift (if wind is high enough). And then kiter makes a mistake, kite surges or even loops and helper looses his grip; rest is simple physics, poor kiter takes off violently.

This counter force explanation also explains how heavy weight kiters can often jump that high. Heavy guys are usually also strong and therefore able to hold a lot of line tension, so they can hold/develop much more lift than light weight rider can. Heavy guys usually use smaller boards compared to their body weights which gives an additional advantage. Low weight riders struggle to find or even don't understand how small boards they should use. And unfortunately there is also a limit when kiteboard is getting too short, too difficult to control.

So it is obvious jumping high is easier when kiter is quite heavy or at least it is not a negative thing (if and when there is enough wind). Jumping needs body strength and good grip to the water, and of course good technique.
