How does baseplate shimming work?

For baseplate board shim naming convention, would you agree with the following? (don’t need to specify “thick end front” each time you mention it)

Yeah thats how I’ve always assumed it, same for tails. But the “more lift” “less lift” isn’t in my opinion good wording to use. Shimming (or moving mast forward/backwards in box) doesn’t magically increase how much lift a wing has which is set in stone. Changes pressure distribution between front/back leg.

Yeah true, I think this version of the diagram is better with some more nuance around the feelings, and the +/- is just to describe the mechanical change

I had a foilparts base shim kit (two 0.25 and one 0.5 degree) liked the finer angle options, but the shims didn’t last long, durability-wise. Ended up getting a PPC 1.0 degree, which seems fine, and is definitely more durable.

@misterbennetts are you doing a positive shim angle in this clip or is it the perspective? I’d imagine in those big waves you’d want negative.

Zane discusses shimming here

Tbh I also thought the opposite to Zane (as does Eric apparently)

In essence, Zane reckons that a Negative baseplate shim makes for a tighter turning radius by giving it more front foot feel and more surfy…

Somewhat interesting to hear.

Pretty easy to swap out/change shims on the Cedrus… 2 screws 20 seconds to change. Also having it attached makes adjustments of the mast forward/backward in the tracks easy. I’ve found with a loose base shim, can bind, be a real pain in the butt. Also, you can get a .25… Cedrus has custom tab when you buy the shim where you specify what degree you want.
