Title: How big is Titanic
Post by: oldiron on April 09, 2013, 03:14:24 am
We constantly hear how big Titanic is. However, someone sent me this picture that puts Titanic's size into prospective in relationship to today's cruise vessels. Witness the Titanic backed by Allure of the Seas.

Well, I know which one I would rather sail on if she were around today.  O0

Titanic passenger capacity, 2453
Allure of the seas pax capacity 5400 (at double occupancy).


And so my question is, how much extra space to pax have today, and what accounts for the rest of the volume of the ship?

From my waterline models of Titanic and Queen Mary 2 I'd say that the picture looks about right.
 
A lot of factors affect space comparisons. A standard cabin in a modern cruise ship would be around the same size as first class cabins in Titanic and not all of them had their own facilities. On Titanic the bulk of the passengers were steerage and accommodated in bunks. Cabin space takes up a lot of space in a modern ship, you only need to look at all those balconies!
 
As far as the other space in the ship is concerned, much of the hull of Titanic was taken up with boilers and machinery whereas on a cruise ship the power to weight ratio of the diesel power plant is much, much greater and the propulsion is often in the form of pods hung underneath the ship. Use of aluminium makes for a much lighter upper structure on a modern ship, permitting more accommodation decks. Titanic was deep draughted and sat in the water, Allure of the Seas basically sits on it and despite her much greater size actually has a draught of 1m less than Titanic. Most of the rest of the difference is accounted for by public facilities. The Titanic didn't have things like outdoor lidos and swimming pools, theatres, golf courses, water parks etc. etc.
 
But of course the two ships shown are quite different types. Titanic was an ocean liner, Allure of the Seas is a cruise ship - different animals.

Some good info on the dimensions of Titanic and how they are taken here: http://www.titanicebook.com/dimensions.html (http://www.titanicebook.com/dimensions.html)

 %% So that's how the Titanic sunk it was run down by a cruise ship and wasn't an iceberg it ran into!

In an Atlantic storm, Titanic might well have been more comfortable than Allure of the Seas!
 
Not so many years ago when QE2 and Queen Victoria crossed the Atlantic together there was no doubt which was the better ship as regards sea keeping.

Most of the internal space of a cruise ship is air, they have to have massive internal atrium's, there is no other way that there can be so much hight above the waterline.

Also, the upper decks of the Queen Mary 2 are inset from the side of the hull to improve stability.
 
Of course, air is what cruise passengers are paying for, large cabins and spacious public rooms and atria. All the heavy stuff is well down at the bottom of the barge like hull.
 
Just before WW1 the Germans tried to outdo everyone else with the Imperator and her two fleetmates and came a cropper. They installed marble bathrooms and other heavy fittings in the first class accommodation and installed huge funnels. As a result Imperator was nicknamed Limperator as by the time she reached New York with her coal bunkers almost empty the ship would list significantly to one side or the other. In the end they had to remove much of the expensive fitments, cut off the top of the funnels and pour a couple of thousand tons of concrete into the bottom of the hull. She was generally OK after that and went on to serve as Cunard's Berengaria after being ceded to Great Britain as war reparations. She carried on until 1938 when she was retired after a series of fires caused by her outdated wiring. When she was built there was only a positive supply wire with the negative return through the ship's structure (a bit like a car!) So when the positive wire lead sheath wore through with the working of the ship, if it touched anything connected to the ship's hull it caused a fire!

Not too worried about the design and the reasons why, just glad to think that two weeks tomorrow I shall be boarding a cruise ship (Crown Princess) in Southampton for a 12 day cruise to the Canaries and back.


Will be interesting to see how she fares across the Bay of Biscay and into the Atlantic rather than round the Caribbean islands.

We saw Crown Princess at St Petersburg in 2008. Not as pretty as Titanic but a lot more comfortable I would think!
 
Have a great trip.
