I had the same problem as your friend with his Blackwater. I couldn't keep the Shadow straight. I am not a bad paddler (finished the 90-miler a couple of times) but I think my technique was a problem with the Shadow. The other possibility is I don't weigh enough to get the Shadow in the water (that is a guess). Regardless, I didn't have this problem with other canoes I have owned (or own) ...Magic, XL Classic, Hemlock Kestrel. I have heard great things about the Blackwater, and now they make a shorter version. But, given my history with canoes i would have to try it and that is difficult. I have paddled both the Rapidfire and the Cruiser (there is a Swift dealer near me) and I like both very much. So, if I can get either one used I will jump on it.
