We bought the mattawa 3 years go and have no major complaints. It's scratched on the bottem enough that it could pass as a map which is a testament to its toughness; I bought it to use. I don't do whitewater except the raisin river race (much fun).The stability always surprises me, I believe you'll fall out of it before it will turn over.It,s not deep but handles waves well as long as you quarter into them. Carries enough for a week. Semi fast not a slug, not a speedster.Really good handling.You can solo it ver easily. In fibreglass 56 lbs. One initial reason for my choice was the trim with myself and my better half.Perhaps being asymetrical helps (wider in the rear),I'm eighty lbs. more than the front paddler. However when I paddle with someone of equal weight it carves heavily. Perhaps a sliding seat would alleviate that. As it came from Swift I found the seats much too low, however you can raise them as it barely affects stability. The carrying thwart is not too comfy for any distance. All in all I'm very happy with it.
