Turns out to be almost the same as the KR2s. The longer boat will be a better

Thanks for the reply. One question though, 1245 lbs? The empty weight of
a stock KR2S is listed on the site as 520 lbs, assuming they're being
optimistic about that I'd assume 600lbs being a more realistic empty
weight. That plus two 180lb people, plus 30lbs of luggage and 95lbs of
fuel comes t
"On the matter of gross weight, 1245 pounds is pushing the limit, but
with a forward CG (use of wing tanks rather than header tank, for
example) and only doing it a few times a year, that's doable. I've

To fit the spar webs I figure I need about 8 ft by 35 inches surface area
of ply to cover all the spars, I would assume the grain in a 8 ft length runs
lengthwise in the sheet, the plans MAKE A POINT of noting the grain to run
vertically, so my question is what do most people do, cut 4 ft
