Space Ships…or Space on Ships

So much is made of the sizes of cruise ships, isn’t it? Some cruisers think biggest is best. Some think smaller is better because of its intimacy. There is, naturally, no correct answer.

In reading about cruise ships, we came across an interesting measurement. Take the size of the ship (measured in “gross tonnage”) and divide it by the number of passengers, and you have a ranking for how much space there is for each passenger.

It’s called Passenger Space Ratio (PSR).

Basically, whether the ship you think “feels” most spacious actually is the most spacious.

The Wise One on our team agreed to rank the seven ships we’ve been on most recently, 1 to 7, according to how spacious they felt. Here’s what she came up with…
1. Celebrity Eclipse
2. Coral Princess
3. Celebrity Millennium
4. Norwegian Epic
5. Norwegian Sky
6. Royal Caribbean Navigator
of the Seas

7. Carnival Ecstasy

The team statistician did the calculations we’d read about and, anticipating PSR and its scores would refute her judgment, came up with this:
1. Coral Princess (46.51)
2. Celebrity Millennium (44.74)
3. Royal Caribbean Navigator
of the Seas (44.41)
4. Celebrity Eclipse (42.81)
5. Norwegian Sky (38.48)
6. Norwegian Epic (38.02)
7. Carnival Ecstasy (34.23)

So, if you buy into the statistical wisdom, the Wise One felt the Eclipse was more spacious than it is, and that the Navigator was less spacious than it is. Somewhat surprising is that Norwegian’s Epic, one of the biggest ships around, was in the middle of the pack for both. And what about Allure of the Seas, the grand-daddy of cruise ships?

The stats are confusing. Allure’s capacity is either 5,400 or 6,300, depending on whether you fill “lower berths” or “all berths.” Most people say the Allure will carry 6,000 passengers, so using that figure the Allure would be next-to-last of the ships ranked here.

Conclusion: Big is not always most spacious.
