Think all luxury cruise ships are the same? Oceania proves that’s not quite true.
Its fleet ranges from intimate ships launched in the late 1990s to sleek new vessels packed with modern touches. Some feel like classic floating boutique hotels. Others are noticeably more contemporary. Yet all of them promise the same hallmarks Oceania is known for. Exceptional food, elegant spaces and destination-focused itineraries.
The tricky part is knowing which ship suits you best.
Because one small detail can make a surprisingly big difference to your cruise.
8 Oceania Ships in the Fleet, With 1 More on the Way
Oceania Cruises currently operates a fleet of eight ships, divided into three classes: Allura, Oceania, and Regatta. A fourth class, Sonata, has been announced.
Each class offers a slightly different onboard experience, so understanding the differences can help you decide which ship is right for you.
In August 2027, a ninth ship, Sonata, will join the fleet. With space for around 1,390 guests, it’s set to become Oceania’s largest ship yet. A sister ship, Arietta, is also planned for 2029, continuing the line’s new Sonata class.
Oceania Cruise Ships By Size
Here’s a breakdown of Oceania Cruise ships by size:
| Ship Name | Guests | Crew | Gross Tonnage | Decks | Length (ft) |
|---|---|---|---|---|---|
| Allura | 1,200 | 800 | 68,000 | 16 | 791 |
| Vista | 1,200 | 800 | 67,000 | 15 | 791 |
| Riviera | 1,250 | 800 | 66,084 | 11 | 785 |
| Marina | 1,250 | 800 | 66,084 | 11 | 785 |
| Regatta | 684 | 400 | 30,277 | 9 | 593 |

The Biggest Ship Is Allura
The largest ship in the Oceania Cruises fleet by gross tonnage is Allura, measuring 68,000 GT.
Having debuted in 2025, Allura is the newest ship currently sailing in the Oceania fleet, and really is a work of art, showcasing the line’s commitment to luxury and innovation.
None of the Ships Are Considered ‘Large’
The maximum number of guests an Oceania Cruises ship can accommodate is 1,250, which applies to both Riviera and Marina, with Allura and Vista just behind with a guest capacity of 1,200.
These four ships are significantly larger than the others in the fleet, making them perfect for guests looking for a high level of comfort and luxury, while still desiring a spacious ship with plenty to do on board.
Regatta-Class Ships Are Half the Size!
The smallest ships in Oceania’s fleet are those of the Regatta class, which includes Regatta, Insignia, Nautica, and Sirena, each accommodating 684 guests.
These ships provide a more intimate and personalised cruising experience. Although they offer slightly less in terms of on-board entertainment and variety, if you’re looking for a smaller, quieter and more intimate cruise, they’re well worth considering.
The New Sonata Class Will Be King…
The two ships set to join the fleet in 2027 and 2029 will become the biggest in the Oceania Cruises fleet.
The first, Sonata, will launch in August 2027 and will measure around 86,000 gross tons, carrying about 1,390 guests with around 855 crew. A sister ship, Arietta, is scheduled to follow in 2029 with a similar design and capacity.

Allura Is the Newest Ship, For Now
The newest ship in the Oceania fleet is Allura, which entered service in July 2025.
She is the second ship in the Allura Class, following Vista, and continues the line’s move toward more contemporary design while keeping the elegant, destination-focused style Oceania is known for.
Allura began her inaugural season in the Mediterranean, sailing itineraries from Trieste and Athens before expanding to other regions later in the year.
The fleet will continue to grow in the coming years, with Sonata scheduled to join in 2027 and Arietta following in 2029, launching Oceania’s new Sonata class of ships.
Regatta and Insignia are older
The oldest ships in the Oceania fleet are part of the Regatta class. The Regatta and Insignia were both originally built in 1998, making them the senior members of the fleet.
Despite their age, they have been meticulously refurbished to offer contemporary comforts, with the Regatta last refurbished in 2019, and the Insignia in 2018.

Big Changes Coming for Nautica
One of the biggest upcoming changes in the fleet affects Nautica, which is set to be completely transformed and relaunched as Oceania Aurelia in late 2027.
Rather than simply undergoing another refurbishment, the ship will be reimagined under Oceania’s OceaniaNEXT programme with a very different role in mind. Most notably, her capacity will be significantly reduced from 684 guests to fewer than 500, creating a much more exclusive, small-ship feel.
A major part of that shift comes from the accommodation. The redesigned ship will feature far more suites, with 179 out of 238 staterooms converted into spacious suite-style accommodation, many with separate living and dining areas. This will make Aurelia feel less like a traditional cruise ship and more like a boutique residence at sea, particularly for guests on longer voyages.
Public spaces and onboard experiences are also being redesigned with extended sailings in mind. Expect enhanced dining venues, new enrichment spaces like a Chef’s Studio and Artist Loft, and more lounge areas designed for relaxing over weeks or even months at sea. Even the spa offering is being upgraded, with all guests set to receive unlimited access to the Aquamar Spa Terrace.
When she enters service, Oceania Aurelia will focus heavily on longer itineraries, including Around the World cruises in 2028 and 2029, as well as a range of Grand Voyages. In simple terms, Nautica is evolving from one of the fleet’s smaller classic ships into something much more specialised, designed specifically for slow, immersive travel on a global scale.
So… Which Is the Best?
The answer to this question entirely depends on who you are and what you’re looking for from your cruise – every single ship in the Oceania fleet has been honed and detailed to perfection, and every single one goes to some of the most breathtaking destinations on Planet Earth.
The best way to understand what the best Oceania Cruises ship is for you is to instead answer this question:
What are you looking for from your Oceania Cruise?
Newer vs. Older Ships
Newer ships like the Vista (and the Allura from 2025 onwards) offer the very latest in design and technology, modern amenities and state-of-the-art facilities. They’re perfect for you if you appreciate contemporary luxury and new experiences.
You can expect that Sonata and Arietta will debut a host of exciting new features too.
Older ships, such as those in the Regatta class (Regatta, Insignia, Nautica and Sirena) have a classic charm and character that comes with age, but if you’re concerned that they’ll look tired, think again: they’re enhanced by frequent refurbishments.
Ships in the Regatta class often suit guests who prefer a more intimate and classic cruising experience, so if that’s you, you’ve got your answer.
Bigger vs. Smaller Ships
Bigger ships like Riviera, Marina,Vista and Allura (plus the upcoming Sonata Class), offer a wide range of dining options, entertainment venues, and activities. They are ideal for those who enjoy a bustling atmosphere with plenty of things to do on board.
Smaller ships provide a more relaxed and intimate setting, with fewer passengers and a more personalised service. They are great for those who value tranquillity and a close-knit community feel during their voyage.
Don’t Forget About the Itinerary!
Clearly, the ship you opt for will play a significant role in your cruise experience, but it goes without saying that the itinerary is just as important.
Oceania Cruises is known for its diverse and immersive itineraries, which offer unique ports of call and extended stays that you’re unable to get from any other cruise line.
Whether you’re interested in exploring the historic cities of Europe, the vibrant cultures of Asia, or the stunning landscapes of the Caribbean, Oceania’s itineraries are designed to provide enriching travel experiences.
Understanding exactly what itinerary options you have available, in conjunction with choosing the ship that suits you best will ensure you experience the best possible cruise for you.
