Did an end-to-end test. Towed the kayak with my bike 5 miles to the lake, then disassembled the cart and stowed it in the kayak. Folded up the bike and bungeed it down on the rear deck. Went kayaking around the lake for a while, then reversed everything and biked back home.
It's a lot slower than putting the kayak on the car, but... I gotta say, it felt pretty awesome to head out knowing I could go anywhere there's water or a trail. And switch between them as needed.
