There seems to be wide acceptance that the correct foil-board riding position is balanced (more or less?) directly over the Center Of Lift of the primary wing? If true, does this also apply to wings such as Slingshot's H4, where the mast is mounted directly into the wing (rather than into the fuselage behind the wing)?
As a beginner, I moved the mast to the rearmost position on the tracks and put two (center-line) foot straps in their respective forward-most positions (LF Happy Pill foil-board). Looking down at the H4 wing, it appears that my stance ends up centered in front of the wing by a couple inches.
I'm in the newbie 'rodeo phase,' trying to concentrate on keeping my weight forward on my front foot. My foil-riding kite-bro (using the same H4 wing) says I may need to move the mast forward 1-2" to compensate for where the mast is mounted into the wing and thereby come closer to straddling the lift of the H4 wing. This makes sense but keeping the board level with the surface is challenging as is (with mast all the way back) and it seems that lift will only increase if the mast/wing is moved forward
