I will have some pics tomorrow.
 Little explanation on what I am building. I like to bowfish  and the yaks arent the best for that but they do let me access places a regular boat cant. like hauling down a river bank. 
 And then I hurt my shoulder again,riding them bulls  was a fun deal when I was 20, not so good in places now so I need a boat to rehab in.
 I need light ,stable , portable,ability to stand up and shot a bow.
 Here is what I have come up with so far 12 ft long pontoon boat 65 inches wide.
Each pontoon will be 2 ft wide 12 ft long 5 inches thick ,laid up from 1 inch foam laminated together.
 The hulls will be detachable and hopefully be able to paddle separately. They will also be built with the option of covering in cloth like a skin on frame,or epoxy and cloth  and will have wood strips inset in the foam so if I decide to I can come back and strip the hull with cedar strips.
 One hull will be laid out enough tomorrow to go do a float test.
