So, this weekend we bought a canoe. I was on the fence about it since the canoe is wider than the rack, but this was easily fixed with a little wood.

We were going to meet up with CrnCnn on Saturday, but in the end we had to much crap to do and our camping gear was in disarray.
But this morning we set out towards Frenchman's Lake (40 minutes NW of Reno) for a nice morning outing.
So yes, it can be done! This canoe is a 14.5' boat. I would not try it with a 17 footer, but it could probably be done.
