Mariner Of The Seas

The 2003-built Mariner of the Seas cruise ship is the fifth Voyager-class Royal Caribbean liner, along with Adventure OTS, Explorer OTS, Navigator OTS, and Voyager OTS.

The vessel (IMO number 9227510) is currently Bahamas-flagged (MMSI 311493000) and registered in Nassau.

History - construction and ownership

Royal Caribbean International (RCI) is a US-based passenger shipping company and travel brand, owned by Royal Caribbean Group (RCG). Founded in 1968, RCI currently accounts for over one-fifth of the global cruise market and operates RCG’s largest fleet by both vessel number and total tonnage.

All RCI ships have names ending with “of the Seas.”

The 3300-passenger Mariner of the Seas closely resembles her sisterships but was the first in her class to receive Royal Advantage upgrades as part of RCI’s USD 300 million fleet renovation program, which introduced Oasis-class features to older vessels. This modernization allows guests aboard a Voyager-class ship to experience enhancements beyond the line’s hallmark ice rink, rock-climbing wall, and Royal Promenade.

Decks and Cabins

Mariner of the Seas staterooms (1667 total, across 33 categories) include 119 Suites, 638 Balcony, 226 Oceanview, 138 Promenade View, and 546 Inside cabins. Most measure 150–160 ft² (14–15 m²), with balconies averaging 50 ft² (5 m²). The largest accommodation is the Royal Suite (1090 ft² / 101 m² plus a 215 ft² / 20 m² terrace with Jacuzzi). There are 26 wheelchair-accessible cabins.

Mariner OTS also has two single-occupancy cabins (for solo travelers) located on Deck 2, behind the Loyalty Desk.

Unlike her Voyager-class sisters, Mariner’s connecting balcony cabins feature removable dividers, as they are not attached to the hull.

The ship has 15 decks, of which 14 are accessible to passengers and 9 contain cabins.

Shipboard dining options - Food and Drinks

Mariner of the Seas features a three-deck main dining room designed around a musical theme, with each level named accordingly. The elegant space includes a von Trapp family tableau and live music on the grand staircase landing. In addition to the main dining venues, the ship offers two notable specialty restaurants: Chops Grille (steakhouse) and Giovanni’s Table (Italian trattoria), both requiring reservations. Giovanni’s carries a US$20 surcharge, while Chops Grille is US$30.

Shipboard entertainment options - Fun and Sport

Royal Caribbean’s signature “Perfect Storm” water slides (“Cyclone” and “Typhoon”), FlowRider surf simulator, Sky Pad (bungee trampoline with optional VR headset), and laser tag (“Battle for Planet Z” in Studio B). The “Perfect Storm” concept was first introduced on Liberty of the Seas and Harmony of the Seas (Oasis-class).

“Splashaway Bay” kids’ aqua park replaced the Outdoor Youth Area and features interactive play structures, geysers, and water cannons.

“The Observatorium” (Escape Room by Puzzle Break) offers group puzzle-solving adventures with time-limited challenges and themed storylines.

Itineraries

Mariner of the Seas’ itinerary program includes Asian cruises departing roundtrip from Singapore, Shanghai, and Tianjin, visiting destinations such as Japan, South Korea, Thailand, Vietnam, and Indonesia.

In 2022, Royal Caribbean introduced a unique series of 8-night cruises from Port Canaveral (Florida) to Bermuda and the Bahamas. The itinerary included an overnight stay at Kings Wharf, Bermuda, along with calls at Nassau (late-night departure) and CocoCay Island (Perfect Day private island). Scheduled departure dates included May 15 and 28, June 5, August 21, September 3 and 11, and October 8 and 16, 2022.

Mariner of the Seas was delivered to Royal Caribbean International on October 31, 2003, by Kvaerner Masa-Yards in Turku, Finland (now part of STX Europe, a division of STX Holding, South Korea).

The ship’s godmother is Jean Driscoll (born 1966), an American athlete and wheelchair racer. She competed in four Summer Olympic Games, winning five gold, three silver, and four bronze medals in wheelchair racing, and holds the record for the most Boston Marathon victories (eight). The naming ceremony took place on November 14 at Port Canaveral (Orlando, Florida). Following the ceremony, on November 16, Mariner of the Seas embarked on her maiden voyage to the Eastern Caribbean, visiting Puerto Rico, Nassau (Bahamas), and St. Maarten.

As one of Royal Caribbean’s larger vessels, Mariner features a four-deck-high Royal Promenade that stretches longer than a football field. This is one of the ship’s most popular public areas—brightly illuminated and visually striking despite having no windows. The interior décor follows an Art Nouveau style, combining elegance and simplicity.

Mariner OTS refurbishments review

Drydock 2026

The ship's last drydocking was in March 2026, at Grand Bahama Shipyard (Freeport).

Drydock 2023

In February 2022, Royal Caribbean announced a scheduled drydock for 2023, resulting in the cancellation of 19 voyages (18 in 2022 and 1 in 2023) from Port Canaveral between January 7 and April 1 (inclusive). Affected passengers were offered rebooking options on Jewel of the Seas, also homeported in Port Canaveral.

The 2023 drydock (February 28–March 25) was completed at the Navantia Shipyard in Cadiz, Spain. The project focused on routine maintenance, classification works, and general hotel upkeep, as well as minor steel repairs (including aft hull cleaning and painting) and propulsion system/azipod overhauls. The Sky Pad attraction was removed and the space converted into an open activity area for complimentary outdoor programs such as cornhole, dance classes, and other leisure games. The sundeck areas (Decks 11–12) received new teak flooring, the waterslides were repainted, and the FlowRider’s pump was replaced.

Drydock 2018

The ship’s 2018 drydock (May 8–June 24, at Freeport, Bahamas) resulted in the following updates:

• On Sports Deck 13, Royal Caribbean added the signature high-speed racing slides “Cyclone” and “Typhoon,” along with the FlowRider surf simulator, Sky Pad (bungee trampoline with optional virtual reality headset), and a laser tag arena (“Battle for Planet Z,” located in Studio B). The new “Perfect Storm” water slide duo was first introduced on Liberty of the Seas and Harmony of the Seas (Oasis-class).
• On Spa Deck 12 (aft), the new “Slashaway Bay” kids’ aqua park was added—an interactive water play area with water cannons and geysers, replacing the former Outdoor Youth Area (“back deck”).
• On Deck 15, the “Skylight Chapel” (wedding venue) was replaced with “The Observatorium” (Escape Room by Puzzle Break), offering immersive, timed puzzle-solving experiences for groups.
• “The Golden Room” nightclub (Deck 3, lower level) was converted into staterooms, while the upper level (Deck 4) became “Izumi,” a Japanese specialty restaurant with teppanyaki tables.
• The Photo Gallery was relocated from Deck 4 to Deck 3. Its former space on Deck 4 was repurposed for the “Playmakers Sports Bar” and an Arcade Room.
• “Dragon’s Lair” nightclub (Deck 3, lower level) was also replaced with staterooms, while its upper level (Deck 4) became part of “Izumi.”
• New dining and entertainment venues were introduced on Deck 11, including “Jamie’s Italian” (Mediterranean cuisine), “The Bamboo Room” (Polynesian-themed cocktail bar), and “Playmakers” (sports bar and arcade).

Additional staterooms were added, and all existing cabins were upgraded and modernized. The 2018 refurbishment project cost approximately USD 120 million.
