when I pulled the floor under the tanks there was a 3/4" strip of plywood screwed to the top of the center keelson , the 1/2" plywood floor sat on top of it and it was flush with the top of the stringers. heres a pic I took of the aft tank bulk head wall as I was glassing it up, you can see the way the center keekson is rounded on top, I raised it with glass and ground it flat to bring it up to within 3/4" the level of the stringers and used 3/4 marine ply for the floor.
