some older Carolinas have a very basic seat, whereas the Tsunami always had the nicer and very comfortable & adjustable Phase3. The Tsunami also has real thigh hooks, and a smaller cockpit opening (size 1.7 vs 2.2 for the Carolina) which will work better with a skirt. Similar hull shapes, but the Tsunami has a little more rocker and a better chine design which helps with edging. If price is not that different, the Tsunami gives you a bit more bang for the buck; but for casual rec paddling some might prefer the wider cockpit of the Carolina.
