About Seven Seas Mariner
Seven Seas Mariner, completed in 2001 by Chantiers de l'Atlantique in Saint-Nazaire, France, was the world's first all-suite, all-balcony cruise ship. She measures about 48,000 gross tons and carries 700 guests with 459 crew. A dry dock in Marseille in November 2025 refreshed every suite, redesigned the bathrooms of the larger suites, added a pizzeria at the Pool Grill and created the Epicurean Enrichment Studio, a culinary theater. She sailed Regent's 2026 World Cruise, and her program ahead includes a circumnavigation of Australia, Grand Voyages to the Arctic, the Mediterranean and the Southern Seas, and the 150-night 2029 World Cruise from Miami to Rome.
