I want to remove the middle seat from my boat. I figured it would effect the integrity of the hull, but after I looked some more I noticed there is a rib right under the seat. So will the hull still be as sturdy? If not will it be a huge difference? Also if I take the seat out I want to put a floor in. How do I go about that with it being a v hull? Do I just stick a piece of plywood in there and deal with the springyness when it bends? Do I put a sheet of Styrofoam under the plywood to aid in support? Ideas? Thanks in advance.
