Yes that would be it. They cost about $500. I have one myself. They are the most easily piloted craft for a river. I use mine going through the class IV rapids of the Gunnison Gorge with little difficulty. They are the best thing for a river, and work good for smaller lakes too. Just make sure to bring an anchor for lake fishing. You can even hitch a battery to the back of one and mount a small trolling motor. Awesome.
