When I first saw photos of these auto barges, I thought of The Golden Ray which half-capsized some months back and has disappeared from the news if you don't live in coastal Georgia.
It carried thousands of vehicles and the plan to right the ship has been abandoned.
What will happen is probably similar to the dismantling of the Tricolor in the English Channel five years ago. It was an auto carrier of about the same size, also tipped halfway over on its port side in just a little bit deeper water.
If you have a spare half-hour or so, this video is a simply astounding account of the operation. Saws and pulleys, imagination and guts!
