The Rhythm 11 seems to be well built but that’s where the pros end. I could not keep it tracking straight. It’s like standing on a ball so the experience is terrible. I called the company and they won’t stand behind it because I can’t locate the original receipt. They came up with excuses why it isn’t tracking but pretty much left me on my own. It’s disappointing that they won’t offer at least some sort of help because of a receipt. The serial number clearly indicates that the kayak is within the 5 year warranty. I’ll be looking elsewhere for my next kayak.
