I am starting my jon boat project (https://www.tinboats.net/forum/viewtopic.php?f=21&t=24099) and 1st up after the all the existing h/w is removed and cleaned out, is installing a floor. My plan is to use sheets of closed cell foam between the cross ribs and put aluminum sheet over it. I want to make sure I have good draining underneigth. Front to back draining is accomplished with moldeded in strakes, but there is not a center strake. Even so, I plan to leave a small gap in the insolation down the middle. Since the top of the floor will retain the shallow V, rain and splash over water will run toward the center. I think its better not to have center drain through floor, and let water drain ontop toward the back of the boat. My reasoning is, that dirt, mud, sediment, will collect under the floor and start filling the water drain passages.
I'd like to hear from others that have done their floors this way. What issues you ran into, what tips, things to look out for, thanks.
