The SS United States
is (or was -- granted she's around, but basically just a sad rusting hulk along the pier anymore...
) an AMAZING ship. Beautiful, clean lines... just a gorgeous ship.
The lengths that they went to in designing/building her was incredible -- even the piano, IIRC, was specifically made of aluminum in order to save weight! During the speed run for the Blue Riband, supposedly the paint on the bow was peeling off from the hull speed through the water.
If you can find a copy, look/read a book called [b]A Man and His Ship[/b[, by Steven Ujifusa. It's basically a biography of William Francis Gibbs (her designer), and his quest to build the SS United States
