When I was prepping my forms for documentation, I used 7.25' from midships deck to keel bottom, based on measurements made in AutoCAD from the profile view. My gross tonnage calculated to about 8 tons, which qualifies--and I know other C27's are documented so it was probably right. But I got to wondering later if I wasn't supposed to use depth of the canoe body, which only works out to about 4.6'--a lot less. That's what's used for scantling numbers and other calculations that consider displacement. But the CG simplified application method is kinda mysterious. I don't know how in the world a C27 would be considered an 8-tonner, although I suppose if I keep buying batteries and gear I'll hit that soon (and ride 12 inches deeper than I should... )
