"Closing the gap" problem
Im 72 kg for 1,77 ... using the i-sonic 107 with the NP RSR 7.8 evo III - deboichet 38 cm fin
The problem is: when i close the gap and start to go faster, the rear end of the sail easily touches the water ... and of course this slow the speed of the board.
I move the mast 4 cm back of the center ... it helped, but prefer not to move it far more back in order to avoid the nose to come up.
Any hints or explanation on that?
