It works fine when paddled solo, but you sit quite high. IMHO, it performs much better with two people in it, and perhaps a bit of weight in the hull. It's taken quite a few beatings over the years, but the effect seems only to be cosmetic, and it continues to perform as well as it did when we bought it. Virtually no maintenance - I'll hose it down, particularly the metal parts on the hatch covers, after sea paddles.
Overall, the Tandem might not be slickest boat out there, nor the fastest, but if you're after a kayak with a range of purposes in mind, then you'd do well with this.
This boat is very flexible, can be paddled tandem or solo with an easy shift of the seat latches. This boat is good for day triping around the harbor and extremely stable. Did I mention that the boat boat is also very stable.
My only gripe is the tracking, the boat tends to zig zag a bit and requires good paddling skills and some coordination between the front and back paddler to keep straight. If the boat were 2 feet longer, it would be a pretty fast sit on top.
For a plastic boat the cobra Tandem is great for beginners and leisure paddles. I used it for adventure racing, but have moved on to much faster fiberglass boats.
Also Cobra's powerflex paddles are WOW! very comfortable and feel great. Oceans' paddles hurt my hands and let you advance very slowly. I wish Cobra made a touring tandem!
