As some of you know, I'm modifing my river rig. Here is what I've done so far. 1. Removed the middle seat (live well) 2. Removed the back bench seat 3. Built the rear floor frame of treated 2X2 Plan: Build a solid 2X2 frame for a raised floor in the rear 8' of the boat floor minus the area behind where the rear bench used to be. This floor will be approximately 3 1/4 inches above the bottom of the boat. Build a good solid frame for a drop deck in the front section of flooring up to the "short deck" front seat. This drop deck will provide side to side support. On this sectin of flooring, two pods will be built. One to mount my stick steering the other to mount my control box. Both pods will be filled with the original floatation that was located in the sides of my live well seat. In the rear section of the flooring where the rear seat used to be, there will also be two pods. Both pods will will filled with floatation from the back bench seat. At the rear of these pods there will be a brace running all the way across the beam of the boat for side to side support and a mounting area for rod holders. The floor will consist of 3/8" plywood covered underneath, sides, ends, and top with epoxy paint. Then on the sides of the boat, I will also install the 3/8" plywood again painted front, back, sides with epoxy paint. Along the top rail I plan on building a flat topped pod four inches deep running fron to back. This pod like the otherw will be completely sealed and filled with floatation. This flat topped pod will make a great place to mount rod holder bases. The idea here is to have as much open floor space as possible. I plan on installing at least three and maybe four seat bases. Three bases will be located to equally allow fishing room for three fisherman. The fourth will be positioned either for driving or on the front "short deck" seat. That's my plan. I know the floor won't last forever and that's ok with me. The floor will be removable and when the time comes to replace it (I probably won't own the boat that long) then it will be a simple matter of removing a few wood screws and replacing the floor.
