Just a little update on my personal progress for your interest.

As I got my kit together (Duotone 2020 7m, Indiana 6.0, Gong XXL Foil) I started to learn this.

1. Session: no wind, bit of wind, learned how to sit on the board and hold the wing to get back
                 Wing can get heavy if you have nearly no wind and you have to hold it all the time.
2. Session: just not enough wind to get me out of the water but good for handling practice of the wing (standing)
3. Session: without wing, but bungee and River --> first flights kneeling on the board
                 This was actually simulating the idea of being pulled by a boat (as I don't have access to one)
4. Session: a bit more wind (12 - 15 kts) with gusts I got on the foil for seconds and crashed
5. Session: Perfect wind (15-18 kts) after some first crashes I got up on the foil and could keep going straight - big smile

Next:
improve my pumping (board and/or wing)
Turn around without falling.

Great sport, I can put it all in my car, carry all the kit in one go, Pump the board an Wing and ready for fun
