Yea I built a multichine hull with open cockpit for a 250 lb. 6' 2" guy and it works great.....the baltic birch frames is the strong point the cedar stringers would be the week link.......has to be junk plywood.....
This boat is a hoot...fast.fun....at 19'x18.5" verry suprised at how stable it is. No problem to get in and out of it in deep water......

Any time you want move a frame you have to make a new frame....take measurments from the exhisting frame and make a new one acordingly.....Like cutting the bottom off the front cockpit frame that hits the calves of the legs, I make a half frame that fits in front of the seat. ....
Allright another tweeker and modifier in the crowd. .......Welcome to the club.....
Converting from SOF to a S&G is really easy....Adding a second chine or pannel is tricky. .....
I am working on my 21st boat, I think...I started off with a wood runabout with a grafted in jetski drive back in 2006......Been human powered since......The 1/8" BBirch is great plywood 3 plys of stiff stuff....I use the 3/8" on a lot of frames except for the partial frames in the cockpit area......My teardrop camper has no thicker than the 3/8"ply annywhere.Some 1/4" and lots of 1/8".......
I plan on building an open cockpit like the ski's. .....l have converted S&G desgnes to SOF so the process could be reversed......
Hard turning is what this guy says about the pax 20....Indicitive of a hard chine hull with little rocker......

Cedar I find it better to "climb cut" with the router to avoid any splintering which cedar has a tendency to do...

I got the chance to paddle a 19' ×19" ski the other day, suprising how stable it was, Yea we changed kayaks in deep water without falling in.......I want to build one....... Sling shot is too wide....CLC'S PAX 20 IS 19.5 " wide.......Jeff do you paddle Sling Shot verry much?.....
Jeff , sent a payment in.....I can't wait to get it, just finished another S&G with a strip deck, a real greenland design.....kind of twitchy going to be fun.....
