I honestly dont believe there's anything wrong with building a replica of The Titanic. With obvious modern internal structures, propulsion (i really dont see men shovelling coal into giant burners), and navigation. Some people will say "why would you do that?"....that's easy, first to complete the voyage that the original never made. second, a nice tribute to those who perished. And finally third, wouldnt it be cool to travel on a vessel decked out from top to bottom in the old style, when ocean liners had class. I mean compared to modern ships Titanic isnt so "titanic" anymore. But it certainly was far more ellegant. Anyway that's just my view.
