I doubt it, but it's worth a phone call, you might be able to work something out. I use a small row-boat now, but used to take my canoe out a lot and know it's a pain, especially alone. I once saw a rig someone was using where at one end of the canoe they attached a couple of lawn-mower wheels. Then they only had to flip the canoe and get one side high enough one the car before moving to the back of the canoe and pushing it the rest of the way up. It looked like it worked pretty well and could be easy enough to make. I hope that I explained it clearly.
