Tiny Boat Build - How to add Flooring to your Aluminum BOAT

I have been using my 12 foot aluminum boat a lot recently and wanted to make it more fishable. The challenge for me is that I could not make it too heavy because I do not and cannot have a trailer for this boat. I would love to have added a big deck, storage , new Trolling motor and more but it would be too heavy so I opted to just add some flooring so that I would have a flat platform to fish from.
