This has all the answers your looking for....https://www.tinboats.net/forum/viewtopic.php?f=3&t=9074. Personally, theres no way I would even consider decking a 36" boat. I did build a small deck on the front of my 1436 but its not a casting deck, more just for a place to mount a TM and a FF and create some storage. I havnt had mine on the water yet but Ive been on a 32" boat and it isnt much differnt than a canoe. I dont see how that 4" could add anywhere near enough stability for a casting deck. This is all personal opinion. There have been several add decks up the gunwales and even more that have made them as high as the benches. My floor will be on the ribs. No higher for me. I dont like to swim when I go fishing!
