The above picture was version 1.0 of rigging a drop floor, which I abandonded as a bad idea due to the seat mount plate sticking out of the front. I have since chopped off this plate, swapped the location of the two crossbars in the pic, and now run the beaver board below what was the old fishing seat crossbar. The drop deck is now suspended with loop straps from the front cossbar and from the stern seat side rails, the cooler that I row from sits on the board and is strapped down through the handles from the front crossbar to the rear crossbar, strapping both the cooler down and preventing the deck from lifting when inverted. The decking is also strapped to the drop bar with 2, 1 ft straps, preventing it from shifting or lifting. When I repurposed the front fishing seat bar and inverted it, it became apparent that is has the same dimensions/bend radii as a standard NRS footbar. Very stable setup. Easy to load, good place for the dog when gear isn't loaded in the back. Additionally, the downward bends in the inverted seat bar increase the area that it makes contact with the back of the cooler keeping it locked in place, no shifting or twisting, and doesn't interfere with the hinge of the cooler lid so it can be opened without interefence.
