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.
