All I'll say is action speaks louder than words, with regards to NCL. I'll believe that the SS United States will sail again when I see it. Until then, I'll stand by my original statement: If NCL couldn't fix up the SS Norway, why would they go through the trouble of renovating the SS United States?
They didn't have to build all of those new ships that they're planning right away. Thus, if they really wanted the Big U to sail again, then they should have renovated the SS Independence and the SS Norway first. But they didn't. Which tells me that they have no intention for returning the Big U to active service.
It has been well over four years since NCL anounced that they acquired the SS United States. It doesn't take that long to do a feasibility study to refit the ship. Just another smoke screen in my opinion.
