I know you've dragged your dinghy up onto the beach -  not easy is it?   And here in the Salish Sea, this task is even more difficult and harder on the dinghy because the beaches are all gravel - sometimes even barnacle covered gravel.  Mike of 
s/v Chalice shows us a way to make the task into a one-man job, and one that protects the dinghy bottom to boot:
Wouldn't it be nice to just wheel your dinghy down to the beach or up the beach? I got the idea from Harry Bryan in Canada.

 Installed. I had to cut a hole in the boat and build a well for it. Not hard and no maintenance issues with the 1" stainless tube and plastic parts.
