This is LAUNCHING A BOARD:
Excellent tips BraCuru
May I add one single comment, I found out back when I used straps :
You can just as easy, or even easier/safer, handle the board with the front hand, if using strap(s)
If you tilt the board up with the front hand, holding the nose of the board, you can get into the front or both straps.
Then you let go of the nose - the huge advantage when learning with straps, is you can hold the board in position now for indefinite time.
You hold the kite with your backhand - so when you move your front hand to the bar and pull forward, it is ready for a long good dive to get up and going
Strapless, you can not hold the nose but only the tail like you show, so VERY different.
Your method works with both straps and without though, so good overall advice.
But would just mention how easy it is holding the nose too, and you dont get your feet into the tail wing/rudder and sharp trailing edges as easy, when you pull the board towards you.
You can start much faster, if you are open to using both methods, depending on where the board is relative to you
(PS: I have too long legs, and too stiff, so not possible for me at all to put both feet on the strapless board while still holding the board with my rear hand - you must be quite agile)
