We wrestled with the same problem with our C and finally went with inflatables since we didn't tow. Our 1st was a tandem 12' Sea Eagle that was too cramped and also punctured twice. Next we bought a 16' Trinity II made by Aire. This one lasted about 4 seasons with 1 rip (repaired) and finally a split seam. This season we will be towing and will put our tandem and bikes on the dinghy. Really liked that idea of the inflatables - easier to setup then mount the kayak on roof. So we'll see what happens. Whatever you do good luck.
