Given that I'm the only Hfoiler in my spot I have to "discover" the riding techniques by my self (aka from vids and the forum).
I trust that most of the Hfoil water start nuances are already in some thread in the forum or in Youtube.
Anyhow, I didn't find tips how to immediate-fly-start.
The other session I did it unintentionally, so during last session I tried to recall\guess how come I did it,
and I think I nailed the details:
During the preparation for the water start, my lower part of the body, including the board, lags about a foot from the upper body and
a fraction of a sec before getting up on the board I swing my legs forward so the CG is a bit backwards from the regular riding spot.
Can anybody ratify/correct/elaborate further?
