Dean,
I plan to achieve this with westen red cedar frame members that are mostly 3/4" x 1/2", with about a 7 oz. polyester skin painted with Snow-Roof and Elast-O-Seal. I was able to get a 35 pound plywood version of the Walrus, but it gained weight when I put extra reinforcing on the deck, built the plywood footbraces, added Pygmy style hip braces and seat back, seat foam, thigh braces, hatches, and deck rigging, it is now over 40 pounds. I built that one with 1/8" luan and mutiple layers of 3.25 oz glass. The first skin on frame Putz that I built weighs 33 pounds.
I'll check out my space situation. It will end up somewhere between 17'6" and 18'. I'll get it as close to 18' as I can. My usual building spot has my wife's Spring Run strongback and forms in it, this one is being built where my wife's VW Golf goes in the winter. I'll have to open up the garage door to walk around it, either that or move my MG Midget outside.
I'm not too concerned about having a lot of displacement, because I want the kayak to have very little freeboard, for low windage. This one will be a day trip kayak only so I am not planning on carrying a lot of gear in it. I have my Tern for camping trips.
If I am happy with the performance of it, I may build a wood and fiberglass verion of it later. I may even build stip panels to do a strip panel stitch & glue like Pete Roszyk. But for now I am prototyping with a skin on frame version.
Cost should be pretty cheap for this one. I spent about $25 on wood, I have enough paint and monel staples left over from my last skin kayak. So all that is left to buy is $15 worth of brass screws and about $70 worth of polyester. Aside from my leftover materials, I'm putting about $110 into this kayak.

: Do you achieve this with 3mm okoume, multiple-thin-glass lay-ups, both?
: As to size, a local manufacturer of stitch-and-glue kayaks put people 175#
: and under in their 17' kayak. Over that and they pointed you to the 19'
: version. They just came out with an 18' version to better fit those of us
: in the middle (I weigh 185#.) If you plan on camping out of it, I'd go
: with the 18' version.: Dean
