When measuring how far lets say twin fins from tail are you measuring from the edge of fin base or trailing edge of the fin?

Trailing edge of the fin, typically......if you're using the fin that the shaper intended for that board.

Some fins are forward on the tabs and some back so you could get a skewed measurement from those.

With FCS, you can usually still see the shapers dot on the foam, which is where the shaper intended the trailing edge of the fin to be.

Futurds doesn't allow you that luxury :toilet:
