Mexico Method
Our marina was destroyed by Hurricane Marty last year. My boat was damaged, but still afloat. Many boats were sunk and the locals used those blue 50 gallon plastic water containers, filled with water, dove down and attached them to the hull. Then they blew air in the containers with SCUBA tanks, pushing the water out. The boats were lifted up off the bottom and could be pulled (slowly) to where they were able to be pumped out. This certainly has minimal cost if you or buddies can dive the boat. Restoration of the interior is another thing. Get it up as quickly as you can. Some of the boats had barnacles on the inside! Good luck.
