The BackBone AFC is a bow-to-stern frame for the Advanced Elements Advanced Frame Convertible inflatable kayak. The backbone enhances both rigidity and performance.
Great product. Enhances the tracking and stiffness of the kayak. Just takes a few attempts to get it right in the center of the kayak. Some practice can make installing easier.
I got the backbone after reading other reviews saying it improved the handling of the kayak. It certainly does. You have to be sure to get it centered though (they suggest using an ink-marker pen to mark the centre-line on the kayak floor). The first time I installed it I didn't get it quite right and felt the boat veering, but when I used it after that I got it centered and the tracking was great. Makes the kayak feel really solid, too, and there's no sense that you're sitting on it. The only thing to note in using it is that it adds weight to the overall kayak during transit.
