Seabourn Quest

She was the third of three identical sisters. Both of the others were sold to Japan while she was still sailing. Then Seabourn took the one that was left and gave her the most comprehensive interior update in the company's history.

The one that is left

There were three of them, and telling them apart was a fool's errand. Seabourn Odyssey arrived in June 2009, Sojourn in June 2010, Quest in June 2011 — all three from T. Mariotti in Genoa, all three to one set of plans, all three carrying 458 guests in a little over 32,000 gross tons, all three with interiors by the same Norwegian studio. When the line called Quest "the third iteration" of the design, it was being precise rather than modest.

Then the fleet started shrinking. Odyssey's sale to Mitsui O.S.K. Lines was announced in March 2023; she finished her published Seabourn voyages on 22 August 2024, ran a farewell from Seattle to Yokohama, and was handed over on 25 September 2024. She sails today as Mitsui Ocean Fuji, marketed in Japan as that country's first all-suite cruise ship. Sojourn's sale was announced in March 2025, and she finished a 129-day world cruise on 15 May 2026 before crossing the Pacific. She is in a Nagasaki yard now, reflagged Japanese, and enters service as Mitsui Ocean Sakura on 19 September 2026.

Which leaves Quest. And the interesting thing about the way this played out is what Seabourn did next: rather than treat the survivor as the one they had not got around to selling, they spent more on her interior than they have ever spent on a single ship.

Two of them left. The third one got the money.

What June 2026 actually changed

Seabourn's own release, dated 4 June 2026, calls it the most comprehensive interior update in the company's history. That is a marketing sentence, but the list underneath it is not a marketing list.

The Club was redesigned around a speakeasy idea, with a new bar, a reconfigured layout and new lighting — and since The Club is where the evening actually happens on a Seabourn ship, and where the sushi is served on this one, that is the single most consequential change aboard. Seabourn Square, the concierge-and-library space that stands in for an atrium on these ships, was reworked toward a warmer living-room feel with bistro seating. The Colonnade got new flooring, carpeting, seating and a new service line. The Restaurant, new carpet and drapery. The Observation Bar, new carpet and furnishings. New water-inspired carpeting through the atrium, corridors and stairways. Renewed teak on the main pool deck, with new sound and lighting. The spa reception redesigned, new gym equipment, an updated salon.

And in every suite category, new mattresses and new wool carpeting, with new veranda furniture in Penthouse suites and above. That last detail is the one that tells you how far down the list they went.

The age question, answered properly

What a 2011 hull is, and what it is not

She is the oldest ship Seabourn operates, and that is the one thing people hesitate over. It deserves a straight answer rather than a brochure one, so here is the case in four parts.

What the arithmetic did to the fleet

Losing two 458-guest ships and gaining two 264-guest ones is not a swap, it is a reduction. Seatrade put it at 916 berths shed against 528 gained — and Seabourn has nothing on order. President Mark Tamis said in February 2026 that the fleet is "right-sized for this moment, for the next couple of years."

The practical consequence for you is not subtle. Marquee Quest dates — the world cruise, holiday Caribbean, high-summer Mediterranean — are competing for a smaller pool of cabins than they were two years ago. Book the sailing rather than the season.

Where she sails, and one thing she no longer does

Quest is in the Mediterranean through November 2026, running seven-day itineraries that link Dubrovnik, Fusina for Venice, Istanbul and Athens, with back-to-backs assembling into 14- and 21-day voyages. She moves to the Caribbean from November 2026 through March 2027. In 2025 she made her maiden Alaska season — eighteen seven-day runs between Vancouver and Juneau, with a team of naturalists aboard, Helly Hansen jackets for everyone and Swarovski binoculars in the upper suites.

Here is the thing to be clear about, because older reviews will tell you otherwise. Quest is not an Antarctica ship any more. She was one: a 2013 drydock fitted her out properly for polar work — Zodiac cradles and davits, holding tanks sized for five days instead of forty-eight hours, deck heaters, a changing station aft on deck five, thermal imaging, searchlights, and captains sent on a ten-day ice-pilot course. She ran Antarctic seasons for years on that basis. But Seabourn now has two purpose-built PC6 expedition ships, and Antarctica has passed to them. Seabourn's own Antarctica pages name only Venture and Pursuit.

One exception, and it is a big one: the 2028 Cape to Cape World Cruise takes Quest back into Antarctic waters and the Chilean Fjords with an eighteen-person expedition team aboard, plus the Falklands, Easter Island and Robinson Crusoe Island. If you want this particular ship in that particular water, that voyage is how.

Who should book her

She is the right ship if you
  • Want the smallest of Seabourn's three ocean ships and the closest thing left to the format the line invented
  • Would rather have a just-refurbished 2011 interior than a five-year-old one on a larger hull
  • Collect long voyages — she is the world cruise ship, and the 2028 Cape to Cape is hers
  • Like the idea that 458 guests can get into harbors the 600-guest ships have to admire from a tender
  • Are booking for late 2026 and want a June 2026 interior rather than a 2016 one that has not been overhauled
Look at Encore or Ovation instead if you
  • Want the taller public rooms and wider circulation of a newer hull — a refit cannot buy volume
  • Want The Retreat, the private cabana deck, or a standalone sushi restaurant; both are Encore-class only
  • Are going to Antarctica, the Arctic or the Kimberley — those belong to Venture and Pursuit now
  • Prefer the marquee Alaska and Mediterranean seasons, which the Encore class anchors

If you asked us to pick

Best reason to book her
A June 2026 interior on a 2011 hull
Ovation was also refreshed in 2026. Encore has never had a major overhaul and gets only a light drydock in late 2026.
Best voyage on her
2028 Cape to Cape, 120 days from Miami
Five continents, an eighteen-person expedition team, and the first complimentary expedition-style experiences on a Seabourn world cruise.
Best short introduction
A seven-day Adriatic run
Dubrovnik, Venice, Athens. Back-to-back two of them if you can; the second week is where the room learns your name.
Best suite decision
Veranda, and spend the rest on nights
Bars, dining and caviar are identical at every tier on this ship. You are buying square feet, not access.
Best thing to verify first
Whether your date is pre- or post-refit photography
Anything shot before spring 2026 shows the old Club and the old Square. Ask us for current images rather than trusting a gallery.

Questions we are actually asked about Quest

Is Seabourn Quest too old to book?

She is the oldest ship in the fleet, delivered 31 May 2011, and she was also the subject of the largest interior investment Seabourn has made in a single ship. She came out of an Italian yard in June 2026 after what the line calls the most comprehensive interior update in its history — The Club, Seabourn Square, the Colonnade, the Restaurant, the Observation Bar, the pool deck, the spa, and new mattresses and carpeting in every suite category. What a refit cannot change is deck height and suite footprint, so if you want the volume of a newer ship, look at Encore or Ovation.

What happened to Seabourn Odyssey and Seabourn Sojourn?

Both were sold to Mitsui. Odyssey's sale was announced in March 2023; she was handed over at Yokohama on 25 September 2024 and has sailed since 1 December 2024 as Mitsui Ocean Fuji. Sojourn's sale was announced in March 2025; she finished a 129-day world cruise for Seabourn on 15 May 2026 and is being converted at Nagasaki, entering service as Mitsui Ocean Sakura on 19 September 2026. Quest is the only one of the three still with Seabourn.

Is Seabourn Quest the smallest ship in the fleet?

No, and the distinction matters. She is the smallest of Seabourn's three ocean ships at 458 guests, against 600 on Encore and Ovation. But the expedition ships Venture and Pursuit carry 264 guests each, so they are considerably smaller. Quest is the oldest ship in the fleet and the smallest ocean ship — not the smallest ship.

Does Seabourn Quest still sail to Antarctica?

Not on her regular schedule. She was fitted out for polar work in a 2013 drydock and ran Antarctic seasons for years, but Antarctica has passed to the purpose-built PC6 expedition ships, and Seabourn's own Antarctica pages now name only Venture and Pursuit. The exception is the 2028 Cape to Cape World Cruise, which takes Quest into Antarctic waters and the Chilean Fjords with an eighteen-person expedition team aboard.

What does Quest have that Encore and Ovation do not?

Scale, and the itineraries that come with it. At 458 guests in about 32,000 gross tons she is roughly a quarter smaller than the Encore class, which opens harbors the bigger ships cannot enter, and she carries the long voyages including the 2028 world cruise. She was also the first ship in the fleet to receive Solis, in January 2024. What she does not have is The Retreat or a standalone sushi restaurant, both of which are exclusive to Encore and Ovation.
