Huge crowds down at the breakwater/cruise terminal today with these three big girls in town - Norwegian Joy, Ruby Princess and Quantum of the Seas L-R respectively. I've been aboard "Joy" as a guest and she is gorgeous but crikey "Quantum" is one big ship seen close up. She's something like 5x the GWT of Titanic for comparison sake.
That said a quick check shows the astounding recent developments in ship design and technology innovation: barely eleven years ago when "Quantum" was launched in 2014 she was the biggest cruise ship in the world at 168,xxx tons - today she is tied with her two sisters for barely 29th place which is pretty astounding. The Joy incidentally is less than 1000 tons less than QOTS, and comes in at the 33rd largest cruise ship on earth.
