It is not just that, it's the physical problems. There is littke to no strength left in the hull, and it would fall apart. Also, you would need to call for some of the biggest ship's in the world, for them to tie it to. Then what, she is a day's ailing from cape race, at least. It is a grave site, and should be treated as such, al that can be done, is some preservation techniques, even rasing the sister ship Britannic which is more feasable, is beyond comprehension, for now atleast. There are possible avenues's to replenish the steel in these ship's, but raising is not likely.
