Atkins Hoyle: http://www.atkinshoyle.com/, makes a quality product. As I recollect the 6000 model (600 lbs) which I put on the Symbol was less than $2,000. It uses a Rule winch which poweres up and down. There is no problem with cable unraveling (this holds true for the 5,000 lb lift for my Grady White and for many off shore racing boats which had Stainless Steel halyards.)
It took me a day to install the davit, including cutting the fairing block. After the upper dock hole is cut, make certain the boat is level athwartships and in propper trim for and aft--drop a plumb bob from the center of the upper hole to mark the lower mount. Use a level on the standing tube as you place it. Since the Sundeck was cored, I sealed the hole with epoxy. The fairing blocks were made of 2 1/2 inch teak and had 8 3/8 bolts around the alumium coller on the top and bottom--thus no extra reinforcing was necessary on the deck. The crane was positioned so that the dinghy could be launched on the stb side or over the swim step.
Yes there is some decrease in visability aft, but I did not consider it a problem. I made my own chocks of 2" stock wood--I had tie downs fore and aft. The boat was a 12 foot Duroboat--alumium skiff, with 15 hp electric start outboard, fuel and battery. One man could launch this in a few minutes. I did not pick up the skiff in heavy seas--but I did pick up a 10.5 foot inflatable in about 4 foot seas--not easy, but could be done.--it would be easier and safer than trying to attatch and pull aboard a dinghy on snap davits in similar seas--which I would consider extremely dangerous.
I have carried motorbikes all over the world--mostly a Honda Trail 90, which I consider ideal--since it has a low range for steep hills, carries two people and has an extra gas tank. I have also carried 50 cc "Yamahoppers"--which weighed about 120 lbs each--and and I have taken both types of bikes ashore in inflatables--but prefered to use a pier.
