I was excited to see that Oru started making a tandem kayak... even better that you could configure it for one person. Overall, I think it goes together easily (each time gets a little easier), and taking it apart is a breeze.
My first trip out was on a windy day (up to 15 mph gusts) as a single. I weigh close to 200#, and what I found was the boat stayed too high in the bow. In quiet waters next to shore, it tracked well. When I got out into the wind, it was a beast to keep in a straight line.
The following day, I tried it with my paddling partner, and it performed beautifully, with winds up to 20mph. The kayak wanted to stay broadside to the wind, but with a lot less effort than the previous day, we could keep going the direction we wanted to go. The same day, I let my partner out, and then tried sitting in the forward seat (rather than the middle one), and that configuration didn't do well in the wind either. My plan for solo kayaking in the future is to stow some ballast in the bow, and see how that works.
Overall, I think it's a very nice option for a tandem, but its performance as a solo (unless VERY calm wind) is a little dubious.
