Too funny.

I am sure Kai's setup is ideal for Kai's super wide stance and foot straps he uses to control the extreme pitch instability he utilizes to perform the most progressive surf foiling in the world. I didn't realize that's what you were tuning to do. Congrats to you.

Thank you for missing the point entirely, once again. I have no problems winging with the most progressive surf foils like he does, and I don't tune my foil specially to mimic anybody, I just use my own wave windsurfing stance and it works super good for winging, and if the front wing is that close to the mast this is the end result. If even my video clip from our small lake, having tons of fun winging with the same super efficient foil that Kai uses in the clip above does not convince you, then let's told leave it at that. You clearly have a really limited view of what winging should be, or perhaps you just don't have winging experience with such foils. Cheers.

I have some observations about where the best seem to be heading and how there setups seem to be changing. I said most not all. I also said not ideal I didn't say unridable. It's like you didn't read my posts or comprehend.

This thread was not supposed to be all about you. Remember, Armstrong shimming.

The discussion was never about the position of the foil on the board as the position doesn't really mean much other than when the board is still planning. This is important but not being discussed by me.

I covered the distance from the front foil to the mast in the first line of my reply. That is the point. I was talking about the whole setup and the turning moment it creates and how it results in where the back foot ends up in relation to the mast,. Note this is while already foiling being discussed here. The back foot is suggestive of where the riders centre of mass needs to be control the height of the foil but height control is relative easy to control with the back foot too far back or forward even. . It is controlling yaw and roll while controlling height that gets demanding on the rider and this is where it helps in my opinion to tune so your back foot is directly over the mast. You could tune by changing fuse length, stab size, stab angle, front foil size etc. Once you have all this correct for ideal back foot position then you can make sure that the position of this foil on your board is conducive to slogging or pumping up with your weight position on the board for balance matching the positioning of the foil relative to your centre of mass for nice lift.

Now i am not sure of your tangent regarding Axis but moving the foil closer to mast as axis has done reduces the torque (lift) and reduces dramatically the pump potential. It arguably helps the rider overpower foil in lift during a tight turn but i am not so sure this is helpful due to upsetting the pitch easy and thereby efficiency of the foil in the turn.

I don't think you read my post as I wasn't making assumption here as i am giving my point as a mechanical engineer and how all these levers are interacting.
