Fin Thickness

[wawaskr]

This season I have been struggling to get my Goode XTRcc to perform as good as my old Goode Nano One XT. In one of the threads about the 9970, someone mentioned something about the recent Goode ski fin thicknesses, so I decided to check mine yesterday. I kind of had and idea about it being thicker than usual because on one of my first outings with the ski, I lost the front depth set screw (fell out due to thicker fin). Anyway, sure enough, the fin measures .100", compared to the .095" fin on my old XT. I measured other ski fins I had, and noticed some in the .085" range. What are the thoughts on performance impacts of a thicker fin vs. a thinner fin?

Thinner fins are faster. Thicker fins have more drag but are more stable.

 

Depending on the alloy thinner fins also have more flex and are more forgiving.
