cut a section out of the middle of the hull to reduce the arizona length deckwise to that of the arkansas & glue both halves together. if have or can borrow a belt sander, turn it over & turn it on to be used as a stationary belt sander. mark off the height of the hull both at the bow & stern as the deck is sloped which is were the belt sander comes in. turn the hull over so the deck outline is on the bottom & carefully sand down to those 2 marks. hull is now sloped so glue a piece of .040" sheet plastic to the hull to be used as the new deck.
