Anyone who has been near Circular Quay would have noticed the Diamond Princess at port in the OPT. Melinda raised the obvious question of how big it was compared to the Titanic.
Passengers + Crew
37.5m (excluding bridge wing)
So the Diamond Princess is about 10% longer and over twice as wide, and weighs about 2.5 times as much. Apparently they both had the same top speed of 23 knots. The height I'm not sure about; the Wikipeida article says the height is from waterline to top deck but the other article doesn't specify. From looking at it, it certainly could be 60m from waterline to top deck, it is extremely tall. This at least gives you some perspective if you get to see it up close; however I think there are other ones just like it, I seem to remember seeing something very similar parked outside Venice.
