Many years ago, I hunted with a buddy out of his small jon boat that had four verticle tube sections welded or maybe bracket bolted near each corner. It just had a nut tacked to it and an L bent bolt to snug down on the push poles. For two to shoot out of that little boat, the two poles with the duck beaks sticking up had to go on the side facing the decoys, and the other side of the boat was snugged into the cattails. Jogged my memory, of some pretty good central Wisconsin duck water and times.
