Pierson,
I just bought 2016 Cayenne a few months ago. I have to admit, this is the first true poling skiff that I've owned but have spent some time on different skiffs of friends and guides.
It appears to be as advertised. I can verify that we've floated in less than 6 inches of water with three people aboard and being fully loaded.
I haven't had the chance to run in true "open" water but we were out crossing some bays in the LA marsh with 25+ winds and it handled very well. It responds exceptionally well to trim tabs which allowed me to "fine tune" the ride as we went. Still, we were only in what could be considered 1' seas but the boat didn't pound and we stayed dry.
I wouldn't consider it tippy, I'm a larger guy and don't have any problems walking around. It has the feel of a larger skiff, to me at least. Our first trip out, we fished three people comfortably...at no point did I feel crowded. Two in the front and one on the back poling platform (a bit windy for fly and made the switch to spin and beer).
I can't give you a true opinion on how it poles because I'm a notice. Again, first true poling skiff for me (other boat was a bay boat) and I'm just starting to learn how to pole to begin with.
One other thing that first jumped out to me was how quickly and easily it jumped up on a plane. I have a 60 e-tec on the back and it pushes it around quite well. If you are in some very shallow stuff, put the trip tabs down, and it will jump right up on a plane without any hesitation.
As far as gas millage, our last trip, we fished from 8 am to about 4 pm and did A LOT of moving around. All day of fishing and we burned 4.5 gal. I don't have the exact burn rate but I was shocked with how little gas we used that day.
Hope this helps and I would certainly test drive one. It's a great boat and certainly better value than most on the $$$ to boat scale.
