OK, So I'm starting to think about my deck. The designer of my skiff calls for the use of 1/2" ply on the deck. Me, I think I wanna save some weight and this is a good place to do it. I'm considering and plywood sandwich system (3/16" plywood / kevlar / 3/16" plywood.) I'm pretty sure I can find some scrap kevlar at a decent price or maybe even some carbon fiber. I think the sandwich system would save some weight. Has anyone done this before? Has anyone run across any test on this kinda layup. I'm gonna try to dig up some info from the Gougeon folk.
