Why is there no floor 17 on a cruise ship

Ever been wandering around a cruise ship, press an elevator button, and suddenly feel like you're losing your mind? Deck 16, then... deck 18? Where the hell did 17 go? You're not alone—this catches people off guard all the time. It's not some engineering screw-up or a weird design choice. The real reason? Superstition. Old, stubborn, deeply Italian superstition. See, in Italian culture, 17 is a cursed number. The Roman numeral XVII can be jumbled into "VIXI," which in Latin basically means "I have lived"—a polite way of saying you're dead. And since massive Italian shipyards like Fincantieri build most of the world's biggest cruise ships, that fear just became part of the deal.

Is it just superstition, or are there practical reasons for skipping deck 17?

Okay, superstition drives the bus here, but there's some practical stuff too. A lot of cruise lines just don't want to freak anyone out—same deal with skipping floor 13. It's like a "triskaidekaphobia" policy, if you wanna get fancy about it. Keeps passengers from different cultures happy and the numbering cleaner. Plus, ship designers can lump technical decks together—bridges, crew quarters, engine rooms—under higher numbers without messing things up. But honestly? It's mostly about tradition and not making people uncomfortable. Engineering doesn't care about numbers.

Which cruise lines skip deck 17?

This thing's most common on Italian-built ships, but it's spread around. Here's who does what:

What is the historical origin of the number 17 being unlucky on ships?

This fear runs deep in Italian maritime history. Like I said, XVII becomes VIXI—"I have lived," which is a euphemism for being dead. Kinda dark, right? Italian shipbuilders started skipping 17 centuries ago because of it. Then, when Italian yards became the go-to for global cruise construction—building for MSC, Costa, even some Royal ships—that superstition tagged along. Now it's just a weird little quirk of ship design that passengers notice and scratch their heads over.

Do cruise ships also skip other numbers?

Yeah, 13's the other big one—triskaidekaphobia, the fear of 13. Some ships skip deck 4 too, because in Chinese and Japanese, the word for "four" sounds like "death." Deck 14 gets the boot in some East Asian cultures as well. But deck 17? That's uniquely Italian. On ships that actually have a deck 17, it's usually a technical deck—crew cabins or machinery, not where you'd hang out.

Checklist: How to find your way on a ship without deck 17

• Check the elevator panel: Look for a jump from 16 to 18. If you see this, you are on a ship that skips 17.
• Study the deck plan: Cruise lines provide detailed maps. If deck 17 is missing, the plan will skip from 16 to 18.
• Ask a crew member: They are accustomed to this question and can confirm the numbering system.
• Use the stairs: Stairwells are usually labeled with the deck number, so you can verify the sequence.
• Remember the reason: If you feel confused, recall that it is just superstition, not a missing floor.
