I was fortunate to find an Ariel a few years ago. I looked at it and immediately had to turn away. Anything that smooth-looking would seduce me as soon as I took the first paddle-stroke. I didn't need another boat, but its siren song drew me back in less than a week. It replaced my Mad River Independence for use on small rivers. It's both steady and lively, leans easily and firms up solid.
When paddled flat, the long, narrow stern section makes it track with little correction.
What really sold me on it was when I leaned it, it suddenly became remarkably responsive - and when I leveled it back down it tracked again, on its own. This is unlike any other solo boat I've paddled. Also, the stern was designed to break loose and skid sideways when leaned to the offside, which it does promptly and without feeling insecure.
I'd give it a 10 but for the weight (a good 50#) and its limited speed.
