I have a 1200 pound rated Marquipt davit crane on the boat (52DB); it stows in the transom "fishbox". It was such a pain to use that I installed Presto davits instead. All the pictures showing davits being used on glass smooth water - ha..... I'd swing the dinghy out to the side of the boat and it was a rock and roll show to get that hook disconnected and connected. That hook and weight beaned me good in the head several times.Never seen a 48 with a Crane before. I got to admit, I like the simplicity. Seems like a great alternative to a hydraulic platform.
