Hi guys, I have a Naish thrust surf foil and lost the rear stabiliser after a wipeout behind the boat. I've made a new one but can't find any information one the profile. Is it an assymetrical profile or a typical profile with a flat bottom ( like wing)
Any advice appreciated
Cheers.

Asymmetric means curve one side flat the other. for rear stabiliser that's top flat bottom curved

It is important to understand that the rear stabiliser is upside down and providesnegative lift to help drive the front wing into a positive AoA.

Shape it approximately 60% the size of the front wing and use NACA 105 or Eppler 387 as a profile. Aspect ratio around 4 should be ok.
