Several years ago I did a lot of research on davits and then decided against them. I just didn't like the looks of what they would do to the boat, and then the problem of davits if when backing into the dock. Until last year we had a soft bottomed dinghy and simply dragged it up on the aft deck. It took a few seconds. Now we have a RIB which I lift out with a halyard and drop upside down on the aft deck. Not as simple, but it works fine.
