@FunoRyota are you asking, could all 67 Radar Vapors (just an example ski) of different shapes/models be setup with the same fin numbers or boot placement? Or a 67 inch HO Works O1 be setup the same as a 67 inch Vapor?
I’m no shape engineer but every different shape/model is going to have such different characteristics, shape, bevel, tunnel width, depth, tail width, the list goes on, that I really don’t think the setup can ever be the same. I do believe fin numbers can often be reasonably close, but that’s never going to be reliably consistent.
I think I may be misunderstanding the question
