Your casting deck came out pretty good, now if you notch out a 2x4 and go down to center of the boat from the back seat to the front seat. Then check and see the side ribs are higher than the center that's the key to it. You may have to trim the center a bit.. Now mark the center of the seats and the center of the plywood, once it all fits and the side are a little higher then you mark each rib on both sides and take a half round course rasp and rasp them at the angle until they all fit . You will have a deep V that is just as stable as any Bass boats, I did the same thing to a 1976 mirror craft deepV and it was unbelievable how stable it was and you could not tip it like you can a regular deep V good luck and keep up with your fishing stuff and boat improvements
