They told you a load of bullshit. LOL.
There has been lots of talk about it, but nobody ever comes up with the money. Besides, a replica would not be practical. The original ship wasn't air conditioned. Only a few of the best suites had private bathrooms. Speaking of which, the toilets then flushed right out into the ocean. That wouldn't be allowed today! The swimming pool used ocean water that was heated to a comfortable temperature. And the original used coal for its furnaces. Not a practical fuel today.
Only a real Titanic purist historian would ever sail it. The general public would be very disatified. And with the costs involved, it would never make a profit.
