Seven Seas Mariner

Seven Seas Mariner is a quarter-century old and Regent keeps giving her the hardest itineraries in the fleet. She was completed by Chantiers de l’Atlantique at Saint-Nazaire in March 2001, she carries 700 guests in 350 suites, and she is the ship the line sends around the world, 132 nights in 2024, 168 in 2025, and the world cruise again in 2026.

The claim she is known for

Regent has always described her as the first all-suite, all-balcony ship in the world. The claim is the line’s own and does not appear to have been independently adjudicated; what is not in dispute is that all 350 of her accommodations are suites, that every one has a private balcony, and that this was true on delivery in 2001, when most of the industry was still selling a balcony as an upgrade.

The number that has aged best is the space. At 48,075 gross tons for 700 guests she carries about sixty-nine tons of ship per person. Her three Explorer-class fleetmates beat her, at around seventy-four, but almost nothing outside this segment comes close, and it is why a 2001 hull still does not feel tight. The crew runs well over four hundred, close to three for every five guests.

Three refits, and what each one did

She has been rebuilt inside more than once and it matters, because the steel is from 2000 and very little else is.

The 2014 refit was the cosmetic one: new furnishings, lighting and wall coverings across every suite category, an LED wall and new seating in the show theater, redesigned Stars, Horizon, Mariner and Observation lounges, a refresh of the then Canyon Ranch spa, and new teak on all 350 balconies. She was back in service on April 8, 2014.

The 2018 work was the substantial one. She spent twenty days at Chantier Naval de Marseille as part of a $125 million fleetwide program: Compass Rose was rebuilt with crystal chandeliers, Prime 7 was redone in sapphire and cream, the library was moved and remade, the pool deck was relaid in teak around a mosaic-tiled pool, and Signatures (the Le Cordon Bleu room she had carried since 2001, and the thing she was originally famous for) was replaced by Chartreuse. That is worth knowing if you sailed her early: the Cordon Bleu association is long gone.

The 2025 refit was about matching the newer ships. She went into Marseille on November 3, 2025, for a full refresh of the suites and public rooms explicitly intended to bring her to the design standard of the Explorer class, plus a rebuilt Pool Grill with a wood-fired pizzeria attached, and was back inside a month, then crossed to Miami and picked up the 2026 world cruise.

None of that makes her a new ship. The proportions, the ceiling heights and the deck layout are from 2000, her suites are smaller than the Explorer class’s, and she has a smaller theater and fewer restaurants. It does mean that “twenty-five-year-old ship” describes the hull and misdescribes the interior.

Where she actually sails

Europe, mostly, and then everywhere. Her heaviest concentration is the Mediterranean and Northern Europe out of Southampton, Lisbon and Piraeus, with a Caribbean and Panama Canal winter out of Miami and stretches in Asia and South America. Fifteen nights is the median, which is the point of her.

The long voyages are hers. On May 30, 2028, she leaves Barcelona on Grand Pathways of Europe, 101 nights to Amsterdam through the British Isles, Iceland, Greenland, Scandinavia and the Baltic, and sailings on her schedule run past 170 nights. She is also about to become the oldest ship Regent operates: Seven Seas Navigator, built in 1999, sails her last Regent season in 2027 and then goes on a nine-year charter to the residential operator Avora Residences.

What the fare covers

The same bundle as the rest of the fleet: unlimited shore excursions, every restaurant aboard with no cover charges, wines and spirits, WiFi, gratuities, transfers, but not flights, which since July 2024 belong to the pricier Ultimate All-Inclusive Fare rather than the base one. That is why a Regent price looks the way it does, and on a long voyage it is where the value concentrates; a hundred-night sailing with an included tour in most ports is a great deal of touring already paid for. Excursions beyond the included list, spa treatments, the boutiques and the casino are extra.

Who she suits

Long-voyage travelers who care more about the itinerary than the hardware. On a sixty- or hundred-night sailing the ship becomes an apartment and what matters is that the crew knows your name by the second week and there are 700 people aboard rather than four thousand. She is very good at that.

She is not cheap. She is among the most expensive ships per night on this site, and being the oldest hull in the fleet does not make her the cheapest; Regent prices her against her fleetmates, not against her build year. She does not suit anyone who wants a new ship, a large suite at the entry level, children’s facilities, or an evening with more going on than a lounge act and a small casino. And if you want a week in the Caribbean, she is the wrong ship here to buy; her schedule and her fare are both built for people going a long way.
