Thanks fellas. I got the boat as a project, the previous owner said it filled with water while docked and he pulled the floor. He mentioned that there was foam, but not very much of it. The stingers are still on good shape, but interestingly enough there's really no frame to speak of for the floor. He didn't pull all of the floor out, so you can get a good grasp of the rest of the structure. He also drilled a few small holes in the hull to drain it, which i couldn't understand why, but it's easily fixable. Got it for free, and the boat it delft is in great condition aside from the mentioned. I'll go get foam I suppose and lay it in. What's a good tool to cut the #2 foam with? I only really have knives or a hacksaw at the moment
