Floor for John boat

I am looking at putting a small front deck and floor in my John boat. I would like to have a surface like most salt water boats have what would be the easiest way to achieve that? Hdpe? Rubberized coating on plywood?

Easy flooring solution





How much do you weigh?
Size of boat?

If you want an easy deck solution and weigh less than 200lbs, I’d get 2-3 coolers that will safely support your body weight and anchor them down or ratchet tie them down so they don’t move.
