Underwater salvage attempt

Hi,

i met the boat owner of the sunken yacht and he was trying to salvage the boat yesterday. It looks like it sunk through an existing through hull on Monday night. They had one 4 ton liftbag and a few 1ton bags. The problem is to fix them low enough to provide enough lift to bring the boat to the surface so you can pump out with a fast pump. Yesterday it was not successful but today they will do another try.

Here are some snaps. Check how the stuff is floating around inside the boat. Cleaning will be a lot of work. Thanks good there was not a lot of Diesel in the tank and it is a steel boat. So renewing electrics and redoing the engine should be all that is needed. The boat has around 4 tons and i guess that at least 4 4ton bags would be required fixed with heavy duty transportation belts at a very low point.
