We carry a 13ft inflatable kayak on the swimstep of our R25 classic. As others have pointed out, we have to shift it to the roof rack or tow it alongside prior to coming to the dock. Also we can't run faster than hull speed with it on the step due to the ends of the inflatable hitting the water. The 25 squats in a pretty deep hole when running at higher speeds. With the tender in question you may have to tow it when running. Or devise a mounting system that raises it a foot or so above the swimstep. That's on my list of projects for this season but I haven't given it much thought yet so don't have any concrete suggestions.
