Wherever you can stand with your feet side-by-side is the "pivot point" of the system, and that seems to be pretty much right on top of the front wing. Which, unless you've got a windsurfer foil, is a couple of inches ahead of the mast.AndersP wrote: ↑Fri Jul 03, 2020 1:53 pmKamikuza
The pivotpoint i not where mast meets the fuselage. It is in front of the frontwings lifting center since the stab is pulling down. Try to to foil with both feet right where the mast is and you will see.
Many pocket boards have the mast almost at the back end of the board.
I'm sure if you could alter the mast to wing mounting length, and then the foil mounting point on the board, that it wouldn't feel or respond the same. Virtually, it'd be identical but the response from the board would feel different.Peter_Frank wrote: ↑Sat Jul 04, 2020 9:23 amKami, you are right the balance point is where you can stand feet side by side.
But you are very wrong about the mast connection being the pivot point.
AndersP is right
On a stabless foil, the pivot point is around 30 % from the leading edge of the front wing.
On a normal foil it is maybe 10 cm further forward, close to the front of the wing.
Because the stab moves the system COE forward.
Also, the pivot point is under the water, at the very wing, not on the board, and never ever the mast.
It does not matter in this respect, where the mast is positioned, forward or rear of the wing, the pivot point is at the same spot on the flyer (flyer = frontwing+fuselage+stab)
The balance point on the board is pretty much just over the pivot point of the flyer, so around the front of the front wing usually, maybe a tad more rear when riding powered because of the wing drag and lever effect
I always have my rear foot behind the mast, as I don't like narrow stance.
If I put it on top of the mast, I would have a really narrow stance on most hydrofoils
But some like this, we are just different
And all we ever do is pitch the board, right?
