If it's an inflatable why not just pop it, roll it and stow it?
I used to tow my cheapo inflatable by hoisting the stern up onto the reverse transom of my Hunter31, lifting it so the only the bow was in the water and the stern tubes rested on the transom.
Reduced drag a bit. Got the engine up out of the water.
Only doing that in the Ches. Bay, no chance of getting pooped and having a dinghy bounce off my head.
