I have a 45' Chris Craft motor yacht (see photo of stern below), and I want to build a Dinghy Davit (Lift) for the stern.
Either I can make a unit that pivots from the waterline and lowers the small boat from the deck level down to the water, using a winch and cable, or I can make something like an Engine Hoist and use hydraulic. Help me think this through. I need to lift a 12' long wood boat which weighs 800 pounds including the 10 horse motor UP from the water approximately 6 feet and then pull it in toward the stern so that it can be tightly attached in the up position while driving the big boat through chop. I have already designed a pivot type, and it works with my 1500 pound winch pulling into position, but the winch does not have a brake so it slowly lets the boat back down. This is why I am investigating the hydraulic method.
The drawing below is the design that I have in mind, please offer any advice on these two methods. I need ideas. How has this problem been resolved before?
