Thanks all for the good advise,
Are you getting the foot of the sail all the way down on the deck of your board by raking it back fully?
Indeed, probably I was to careful, so good hint.
Also, where are you running your mast foot (relative to the mast slot in your board), in the middle..... forward.... back?
Actually, I did not really watch this. Probably in the middle. My first quess would be to move in backwards to balance more the heading down?
