[QUOTE="fwman1, post: 498847, member: 31515"] I think that it could work well with some additional supporting structure. My goal was to have as [U]little[/U] supporting structure underneath as I could get away with. It is all built with 2" angle of 1/16" aluminum from Lowes. Very light! I actually believe I have more than double what I need. After using the deck, I believe a perimeter support with a single center support would have been fine. The strength come from both shear and compressibility being very limited. That being said, the support structure adds very little weight to the boat. I can remove two bolts and the rotate two aluminum tabs and remove the entire deck in under a minute. It only sits on the minimal framework, as you can see on the prior pages of this thread. If you wanted to compartmentalize the deck to have easily accessible storage, you'd just need to provide the supports under the cutouts to prevent shear forces being able to accumulate at the cutouts. I think the more difficult engineering would be coming up with a satisfactory hinging system. The thickness of the composite comes into play here. I'd be more inclined to use some sort of twisting lock tab under the support structure of removable panels. An attached strap hinge would probably be the simplest way to go. You could drill a 1" hole in the material and epoxy in a dowel to support the twist lock tab mechanism. Just some rambling. There is a lot of flexibility here. I didn't mention this material adds flotation to the boat. There is easily over 2 square feet of flotation added to the boat between the deck and the center walk area supports. Always nice to have.
