Baseplate shimming

Trying to understand;)
I have a foil that are super lifty (made for windfoil) so I stand in front of mast prone or winging.
Question:
Will a baseplate shim high under back bolts make me be standing more over mast rather in front of the mast?
Appreciate clearing :pray:
Aloha

in theory, that would make the foil liftier at takeoff, but once flying your balanced position should be slightly further back.

Before base plate shimming, have you tried negative shimming the tail for less lift (lifting the front bolt of the tail)?

Thanks, that’s interesting.
Haven’t tried negative shim on tail but that’s a good idea to test

I think foils made for windfoil have a longer distance between the front foil and the mast since they’re designed to be mounted more towards tail of a windsurf board. That would explain why you have to stand in front of the mast.

Wingfoils usually have quite a long fuselage also. You might want to consider a foil meant for wingfoiling instead.

Meant to say “windfoils” have quite a long fuselage also.

Thanks but it’s meant for winging too I think, it’s the Helios MFC ones. They are super fun but a little slow. Compare to the hydros on same fuse they still need to be further back in boxes to conquer that lift.

Looks like they’re made for all types of foiling but the windfoil packages have a 76cm fuselage vs the wingfoil packages with a 69cm fuselage.

You might get a different feeling with the 69cm fuselage if you haven’t tried it already.

Yes I’m on the 69 fuse. I’ll try base shim next time and feel the difference…

You could also try a smaller stabilizer if the negative shim on your current stabilizer doesn’t help enough.

Thanks, going to try that for sure

Forgive my confusion…I’m currently using a Cab h-1300 (med fuse, 180 monobloc tail, no shims) for SUP DW in decent wind bumps. Generally loving the feel so far, as compared to my Kujira 1440 which I learned on.

Most of this could just be a matter of modifying my technique/me not yet having much time on this new (to me) foil. I’m experiencing some minor nose diving as I increase speed into the bottom turn.

I know the Cab foils are designed to have a more progressive lift, but I’m trying to create a little more front foot pressure than exists right now–I’m wanting a little more front foot pushback as I carve back down the face during/after a top turn. Mast is as far forward as I can place it on my Appletree 7’7" narrow.

What should I try first–shim stab for more FW lift? Don’t love the idea of slowing down my rig, though

Or base plate shim, thick side in front? I know this will change my board angle to slightly nose up, but will it actually feel like more front foot pressure?

Or base plate thick side in back. Which seems like it could exacerbate any existing nose-diving…

I know this has been talked about, ad nauseam, but I’m still a little confused about base shimming, and feel like I hear conflicting approaches from some riders (Zane, Eric, etc)

Cheers!
