I would think carefully about lifting that much weight with the mast and boom. My GB is 46' and my Whaler weighs about 700 pounds. I lift it with an electric crane and the boat lists as I lift it. Once it's in its cradle the list is gone, however it sits across the boat deck, not on one side as it would on a 42.
