Ocean Marine Systems built the davits for Hunter for many years, I don't know if they do anymore. We bought ours from them. He asked about our dinghy size, weight, which side we wanted to carry the motor on etc. and custom made a set that fit like a glove. Very well finished and they fold in when we are hauled to save a few bucks. They also provided an excellent installation manual that detailed how to modify our dinghy for lifting, how it should fit in the davits so could not move at all. If a dinghy moves it can shock load the davits dropping off a big wave. Even just a slight movement on the ocean can easily rub through the fabric on an inflatable in just one cruise.
