has anyone ever heard of this meathod of building?

I got the idea to make a series of laminated beams like deck beams but they would form the hull instead of the deck. use them kind of like you would a form in building a stripper but the beams would be permenent. I would glue the beams to a 1/8th inch peice of plywood and the hull should form up nicley.... right? this seems kind of wierd. and how would I get rocker in? I know this sounds crazy but I'm trying to build a flatwater squirt boat. for myself and my friend. if anyone out there has a way of finding volume roughly I would love some advice. thanks for any help you can provide.
