Well, knocking about in rivers, backwaters, small lakes, ponds ... especially where I have to tote the boat any distance, this Radisson square stern is hard to beat. I've beat mine in the brush, threw it in back of the truck, loaded it on top of different cars and even my little popup camper.
Note the weight of the 12' model.
