I have been wondering this for so long what are some methods of raising ships? the only method ive ever seen was raising a boat with ping pong balls on myth busters

I wonder did anyone find the heart of the ocean, know that the
"Titanic" has been under for many of years.
The Heart Of The Ocean is a heavy blue diamond shaped heart, that flooded with the "Titanic" when it had it's last reel.

the heart of the ocean wasn't real...

while a part of me understand that raising the titanic could destroy the titanic and would be seen as cashing in to some people. I personally believe that raising the titanic would be better for it. my reasoning is:

1) The titanic won't be there for much longer due to the disintegration of the metal.

2) when the titanic finally disintegrates what will then be left to remember those who perished apart from a piece of debree and the memory as well as the points on the map?

3) while an attempt to raise the titanic would be higly risky and would take considerable planning, raising the ship, leaving it in its current state and in its pieces but on land, would to me serve as more of a permanent reminder that can be viewed (obviously not used as a walk on piece just a visual piece)

These ar ejust my opinions and this will never happen but i wanted t my view across as a way in which it isn't seen as money making (dont confuse what i said about viewing a personal reminder) and would act as a permanent tribute to those who perished.
