I am giving some very serious thought to building a layout boat. I have looked at sveral sets of plans for them and I would like to know if anyone has any experience in this area. I would also like some input on an Idea Ive cooked up. My pops has a bunch of roofing grade styrofoam that is left over from a job. I hought about gluing these together to get my overall thickness and shaping and hollowing form there. I would then fiberglass epoxy it with some resin that is not petro based so it won't eat the foam. my only concern is that it wouldnt ride right. let me know if this sounds foolish or feasable.
