The Great Surf foils Spec continue

Got my hands on 4 mors sets of foils
F-one Sk8, Axis Surge, Lift Vario, and Naish Siren
I measured up what I had on hand. its pretty interesting, for me atleast!

Im going to add in on the mast length what size it Actually says on the mast, vs what i measure. its interesting im not really sure how they measure?! 
Im measuring from bottom of the base plate to the top of the mast head. then measuring with the fuse on as well, so then to the top of the fuse. Damn, should i measure the mast head to see how thick or tall that is. More specs the better?  For a tuttle fitting i guess that makes sense, but for a saddle, does not seem to be the issue.  

The front wing measurement is the thickest part on the front section of the foil. if there is Fuse build up in the center, im skipping that and going just to the side so its only the thickness of the foil profile itself. 

Front to back wing is the fuse length. From front of the leading edge of the foil to the back of the tail trailing edge. not to the tip of the fuse. as that felt the cleanest. When i measured the Axis like this, it matched the exact spec they have on the fuse. They seem to be the only ones that got all the specs right.

what else to mention? This the the gear we tested. So when we talk about the foils, you know the specs and the lengths of what we rode.
