ok stupid question time. well I have a little sears sea v bottom al hull with albumin bench seats I have been wanting to add a pedestal seat in it but I do not have a wooden floor just the metal skin. I was concerned in trying to mount to the hull and the bench seats are filled with styrene to keep the boat afloat if it were to get a leak in it. I was wondering if I'm just go and install a floor into it to pull this off?
