I have paddled it down class III(IV) water many times, and I've not been gentle with it! I do own other whitewater canoes that have more rocker and are more agile in tighter, technical water, but I still love this old tank.
I've gone river camping on class I-II water many times, and the 13'3" size is big enough for me to bring all the gear I need, by letting out some air in the airbags and packing my gear underneath them. Most of my paddling buddies are kayakers, but canoeing is a different kind of a experience, and my Mohawk XL13 fits the bill. My kayak friends always ask if I can carry gear for them down the river, and I'm happy to oblige with the extra space.
More advanced whitewater canoeists will want something shorter, lighter, and edgier. If you are just beginning, and want something stable, it's a good boat that you may never want to give up. The many scratches and scars I've given it over the years just add to it's character. It still paddles great.
I learned how to paddle whitewater with this boat, so it has seen it's share of rocks and abuse, but the hull is still solid and the canoe performs reliably. It's a solid river runner, and it will side and front surf on "Jaws" (Nolichucky) quite easily... it was never designed to be a rodeo playboat, so I don't deduct points here.
I've had my share of fun with it, and the factory direct price I paid plus shipping made it the best value (I shopped and compared EVERYWHERE!) and a great choice for any beginning to intermediate paddler.
The advantage of it's 13'3" length is that if you want to do some overnight tripping, you've still got space for your gear under the air bags (when you let some air out.)
I own several boats, but would be hard pressed to let this old faithful go.
