Ammo box is one of those elusive pre-WWII side openers originally used for .50 cal BMG I believe. I glued some foam rubber on mine and usually sit on it only when in an onshore blind. I'm too tall and gangly to row my Duckers while sitting inside and so have to sit on the dogdeck. Dogdecks on both ends is another nice feature on these duckboats. I put an old piece of carpet on the bottom to reduce noise.
