I think it is all about tensioning the body / muscles so every pull of the kite/wind gets towards the board to be turned into speed, same as with the racboards ( kite and windsurfing), the more you turn your torso upwind the better your angle upwind is and kept because of tensioning all the mucles,
On the other hand, bending the knees etc, will result in less transportation of power towards the board.
Secondly you can hold more power as you can lean more against the board anbd pushing more power with less (power) loss towards it.
See if people are pulling ropes they also put themselves more on their have more bodytension and better weight balance to hold the forces or pull...
Its only my opinion/experience...

Because on an hydrofoil, the front leg acts as a spring that controls the horizontal level of the board.
pro-riders had same position on ol raceboard. is only about upwind angel.

Maybe their legs and foot straps are just where they want them, but because of the relatively lower speeds going upwind they need less front foot pressure, so they lean their torsos back to compensate?
When going upwind on a long strut race foil, the board is leaned over 45 degrees or more. The kite is at a low angle to the water, so pulling mostly horizontal. Pushing on the on the back foot does more to turn the board upwind than it does to increase ride height.

Also at this angle, the riders weight is not lined up with the foil lift. Since the pull of the kite is from the hips, the hip position is more important than torso position.

I never really thought about it, but after drawing it out, it's crazy that we can ride like this at all! (back leg locked, kite as low as possible, board leaned over as far as possible) There are so many angles and variables and the kite force is constantly changing. Add in chop, and it seems impossible!

IMHO hip forward allows rider to keep his front leg more stright = less effort.

Apparently no consensus whatsoever about this he hee - a bit funny actually :rollgrin:

Some says it is for having more pressure on your front foot to keep the wing down.
Some says it is for having more pressure on your rear foot to keep the wing up (as you ride with lower speed upwind).
Some says it is for having your front foot straight to convert all gusts to upwind/speed.
Some says it is for having your rear foot straight, and flex on the front foot.
Some says it is for having both feet straight and locked, and twisting for upwind drive.

The only thing I think we all agree on, is that twisting your body (hip and or upper body) "upwind" drives as high upwind as possible.

Personally, I think the latter is the reason, namely like Dave says, locking both feet will make good riders able to convert every small and big gusts or windchanges to more speed or upwind angle, and twisting drives everything upwind :naughty:

I would go on the latter too. To really fly upwind stability is key so I would add that leaning forward (rather than leaning backward) allows for more liberty to correct/adjust position with minimum loss of momentum/off set from the “sweet spot”.
