A couple of things to keep in mind should you get a pair of the SitnSail wing seats.
NUMBER ONE: When you are attaching the seats to the brackets on your boat, HAND TIGHTEN as far as you can go BEFORE you use any kind of wrench. It is VERY easy to cross thread and hand tightening is the best way to prevent this from happening. I learned this from experience!!
Number two: The rubberized paint on the seats is very susceptible to scratching and rubbing off. Be careful of bumping, scraping, dragging, or you'll be repainting them soon. An alternative (which I plan on doing this winter) is to fashion seat covers.
Other than that, the seats are wonderful and have greatly increased our enjoyment of the H16. Sort of turns it into a turbo Getaway.
