Closing on the purchase of a boat is contingent upon accepting the results of an inspection by a certified marine surveyor. You pay the surveyor a bunch of money and he goes through the entire boat from rig to keel including (almost) all the electrical and mechanical systems. (Ours missed checking the batteries but a thousand dollars later we had brand new ones!) Part of the inspection is the haul out to check the hull and other bits hidden below the waterline.
The boat was located just south of Miami. For our inspection we needed to sail the boat up the Miami River to the boat yard for the haul out. The boat weighs about 22,000 lbs so the lift used for the haul out is not small.
