This should make things so you cannot push SIDEWAYS as much as you do on your formula board.
I did not say the body needs to be "near the fin". What I mean is that your weight needs to be more inboard, and pushing down (vs sideways).
I think the fin box and rear footstrap arrangement (you are using two rear straps.... right?
will put your back foot just over the front of the fin, which is about right.
What you want to do, is keep the pressure DOWN on the fin to keep it in the water, but put less sideways (across the top of the water to the lee side) pressure on the fin so you don't push it loose and spin out.
When you are going fairly slow, you can't push hard because there is not enough water velocity past the fin to take very much side pressure.
When you are going much faster, you can increase the pressure some, but never pushing hard like on formula with a 70 cm fin.
Hope this helps,
I sailed today for the first time after this reply, and follow your advise.
It was a great day for windsurfing and for testing your tips.
The wind was 25 knots +, so it was also choppy. I sailed with 5.3 sail most of the time overpowered.
I have to tell you i did pretty well, and had much more control, so i really have to thank your advice. The best 2 tips were:
-Change the rear strap position
-Put the weight inboard
Those 2 made the difference, now i even feel more confident to jump, which i was not doing before.
Sailed for 1 1/2 with just 2 spinouts, which is much less for me, and i wasn't in good position at the moment.
Will keep you posted!!
