R23- A big no from 72 year old singlehanded me. I first bought a 12 foot kaboat from ‘Boats to Go.’ It was too long for the roof top, but otherwise perfect. I wish they made an 8’ version of that dinghy.
I then bought a manual Garhauer crane to stow another 70 lb inflatable on the roof. It’s a very well built quality product. However once up there the R23 became somewhat top heavy. Further, the dinghy was stowed right side up so it needed a taut cover to keep water out. Getting that installed after it was up there was a project in itself. And when the temp dropped the dinghy drooped along with the cover. Note I also had to modify the rear cross bar with a deep V to accommodate the V bottom shape of the dinghy.
I then switched to a west marine slat dinghy and stowed it upside down up there by lifting it up over the bow rail and then wrestled it the rest of the way on top. Still had the drooping problem.
Now i just roll it up and stow it in the lazarette. Or i put it, inflated, upside down over the motor…..see pics in my album.
