When you put the floor in the middle of the boat, was it "level"? I have a similar, though much older, v-hull that I would like to put a floor in. I don't have the middle seat section like you have, so I wouldn't have to cut out that section. It just seems like when I put the plywood in to fit, the whole piece angles downward toward the front of the boat. Will that change when I get it on the water?
