Most people assume the newest cruise ships are the cleanest. It makes sense—modern systems, fresh interiors, and the latest tech should give them an advantage.
But when you actually look at the data, one older ship from Royal Caribbean is proving that consistency matters more than age.
Jewel of the Seas, which first launched back in 2004, is still putting up near-perfect health inspection scores in 2026.
And not just once—but repeatedly. It’s the kind of performance you’d expect from a brand-new ship… not one that’s been sailing for over two decades.
A Pattern You Can’t Ignore
When you dig into the CDC’s Vessel Sanitation Program reports over the last few years, one thing becomes clear—this ship isn’t just “doing well,” it’s consistently outperforming expectations.
Across hundreds of inspections industry-wide, only a handful of ships hit perfect scores multiple times.
What’s surprising is how often this older ship shows up in that top group.
Recent inspection scores:
- January 2026 → 99
- September 2025 → 100
- April 2025 → 97
- September 2024 → 100
- April 2024 → 97
- September 2023 → 100
That’s three perfect scores in about two years, which is rare even for much newer ships.
Not Just a Hot Streak—A Long-Term Trend
This isn’t a short burst of good performance. When you zoom out and look at the ship’s entire history, it becomes clear that high scores are part of its DNA.
Over the years, the ship has built a reputation for strong sanitation standards that just don’t seem to slip.
Lifetime performance:
- 14 perfect scores
- 37 total inspections
- Average score: 97+
That level of consistency doesn’t happen by chance—it’s built into how the ship operates every single day.
What “Perfect” Actually Means at Sea
It’s easy to think a score of 100 just means “everything looked clean.” But in reality, these inspections go far deeper than that.
The Centers for Disease Control and Prevention runs unannounced checks where inspectors go through the ship in detail, and even small issues can cost points.
These inspections aren’t quick walk-throughs either. They’re detailed evaluations that look at how well a ship manages health risks behind the scenes.
Areas inspectors focus on:
- Food preparation and kitchen hygiene
- Drinking water systems
- Pools and hot tubs
- Cabin cleanliness and housekeeping
- Ventilation and air quality
- Pest control systems
- Medical facilities
- Kids’ areas and shared spaces
And here’s the key:
Even something minor—like a missing label or slightly off temperature—can lead to deductions.
So, How Does an Older Ship Stay This Good?
You’d expect wear and tear to make things harder on an older ship. Plumbing ages, systems need more upkeep, and operations get more complex over time.
But somehow, this ship keeps delivering results that rival the best in the industry.
The answer isn’t one big factor—it’s a combination of small things done right, over and over again.
What keeps standards high:
- Regular technical maintenance and upgrades.
- Strong daily cleaning routines.
- Strict food safety practices.
- Constant monitoring and logging.
And most importantly—the crew:
- Housekeeping teams maintain cabins daily.
- Galley staff follow precise hygiene rules.
- Crew trained to spot and fix issues instantly.
It’s not about reacting to inspections—it’s about being ready every day.
Why Newer Ships Don’t Always Win
It might sound surprising, but newer ships don’t always dominate these scores.
While they start with modern systems, they also go through a learning curve. New layouts, new teams, and new operations can lead to small mistakes early on.
Older ships, on the other hand, often run like well-oiled machines. The systems are familiar, the crew knows the routines, and everything is fine-tuned over time.
The reality:
- New ships = advanced tech, but early adjustments.
- Older ships = experience, stability, consistency.
And in inspections like this, consistency often wins.
How It Compares to Other Ships
There are definitely other ships that have scored multiple perfect 100s recently, but most of them are much newer. That’s what makes this case stand out even more.
Other strong performers:
- Oceania Vista → multiple perfect scores.
- Disney Wish → multiple perfect scores.
- Norwegian Bliss → multiple perfect scores.
But these ships are far newer, making Jewel’s performance even more impressive.
What This Means for Your Cruise
For cruisers, this is actually great news. It proves that choosing an older ship doesn’t mean compromising on cleanliness or safety.
In fact, in some cases, you might be getting a more consistent experience.
At the end of the day, sanitation isn’t about how new a ship looks—it’s about how well it’s maintained and how disciplined the crew is behind the scenes.
Quick reminder for passengers, too:
- Wash your hands regularly.
- Follow hygiene guidelines onboard.
- Be mindful in shared areas.
Because yes… passengers play a role in keeping ships clean too.
Experience Beats Age
There’s something impressive about a ship that quietly does its job year after year without slipping.
Jewel of the Seas may not be the newest or most talked-about ship in the fleet—but when it comes to cleanliness, it’s clearly one of the most reliable.
Not the flashiest
Not the newest
But one of the most consistent
And honestly, for most cruisers—that’s exactly what matters.
