Luckily, on Bull Shoals there is a dock adjcent to most launches. Even where there are none, the water is quite deep, and my boat floats easily. So I use a line to retrieve my boat, I just tie it to the hitch. When the boat floats free, I pull it up on the shore. Where there is a dock, I use a spring line attached to the cleats fore and aft, with a hauling line in the middle. I launch the boat to float free, then pull it to the dock with the spring line. Makes it fairly easy for this old dog too.
If you're too busy to go fishing, you're too busy!
