Quantum Of The Seas Review

Review of Quantum Of The Seas

The 2014-built Quantum of the Seas is the first Quantum-class Royal Caribbean vessel, with sisterships Anthem OTS (2015) and Ovation OTS (2016). Similarly designed are the "Quantum-Ultra Class" Spectrum OTS (2019) and Odyssey OTS (2020).

The vessel (IMO number 9549463) is currently Bahamas-flagged (MMSI 311000267) and registered in Nassau.

History - construction and ownership

Royal Caribbean International (RCI) is a US company, trademarked brand and subsidiary owned by Royal Caribbean Group (RCG/shipowner). RCI was established in 1968 and currently has over 1/5 of the worldwide cruise market. RCI also has RCG's largest fleet by both vessel number and GT tonnage (ship sizes and capacities).

All RCI liners have names ending with "of the Seas".

The 4200-passenger ship Quantum OTS is a next-generation Quantum Class ship. The new class of ships was known in the past under the name "Project Sunshine". The Quantum-Class is larger than the earlier Freedom by 13,000 GT. With these new dimensions, the class became the second largest in the fleet of the cruise company after the Oasis class.

Itineraries

Quantum of the Seas itinerary program is based on 4- and 5-day short Asia roundtrip cruises from Shanghai and Hong Kong. During her Inaugural season, Quantum operated on Caribbean voyages out of Bayonne (Cape Liberty) New Jersey.

During winter 2019-2020 (November through April) the Quantum ship was homeported in Singapore for a total of 34 itineraries to Penang Malaysia, Phuket Thailand and Ho Chi Minh City/Saigon Vietnam. This deployment increased Royal Caribbean's passenger capacity in Singapore by 30%.

Starting on December 1, 2020, the homeported in Singapore Quantum OTS became RCI's first ship in operation since the fleet pause on March 14. The season (later extended through February 2022/14 months) had scheduled only Cruises to Nowhere (2-3-4-night "Ocean Getaways"/roundtrips) available for Singapore residents only and with no call ports along the route. The liner's max passenger capacity (4819) was limited to just 1000.

During summer 2021 (May through September), RCI planned to deploy Quantum OTS in Alaska - joining there the fleetmate Ovation OTS. Both liners were scheduled to operate 7-night roundtrips from homeport Seattle WA (leaving on Mondays). RCI's Alaskan season 2021 also had itineraries planned for Radiance OTS and Serenade OTS - both homeported in Vancouver BC and Seward AK (7-night one-ways). However, in late-January, RCI canceled Quantum's Alaskan 2021 season (April 25 through October 14) and the ship remained in Southeast Asia. Ovation-Serenade-Radiance ships' Alaskan schedules remained unchanged.

Following Ovation OTS, Quantum OTS became the second RCI vessel deployed in Australia (season 2022-2023). Quantum's inaugural Australian season (Nov 1, 2022, thru April 12, 2023) was based on homeporting in Brisbane QLD, and 6- to 10-day roundtrips visiting NSW (Sydney), Tasmania (Hobart), Queensland (Airlie Beach, Yorkeys Knob, Willis Island), South Pacific island ports in New Caledonia and Vanuatu, as well as 2-night/3-day Samplers (cruises to nowhere).

In November 2025, Quantum OTS starts homeporting in Los Angeles (joining the fleetmate Navigator OTS) to operate 3- to 6-day roundtrips to Baja Mexico. Quantum's 2025-2026 season (October 2 through April 21) grouped 11 different itineraries and a total of 44 departures out of LA. Cabo San Lucas is visited for a 2-day/overnight stay.

Quantum Of The Seas Wiki

On February 11, 2011, under “Project Sunshine”, the shipowner RCCL announced the order of a new vessel. It represents a new passenger ship class of all three units, the first of which (Quantum) was delivered in 2014. On February 29, 2012, RCCL announced the order of the second “Sunshine” ship – Anthem (launched in 2015).

On January 31, 2013, the new vessel class was officially named “Quantum Class”. On this day were also officially announced the names of the first two vessels – Quantum and the Anthem OTS. The third vessel of this class (Ovation) was scheduled for launch in April 2016.

Quantum OTS is Royal Caribbean's first Quantum-class vessel, with "WOW" sisterships Anthem of the Seas (2015) and Ovation of the Seas (2016). There is a possibility the RCCL cruise company to order a fourth Quantum-class ship, as such an option was included in the contract.

Ship's godmother is Kristin Dawn Chenoweth (1968-bornUS actress and singer). It was delivered to RCI on October 28, 2014. Quantum OTS was initially homeported at Bayonne's Port Cape Liberty (New Jersey). The Inaugural Cruise (maiden voyage) was on November 2, 2014. The itinerary was a Transatlantic crossing from the UK to USA (Southampton to NYC / Bayonne NJ). In 2016, Quantum was homeported in Shanghai China for roundtrips to ports in Japan and South Korea,

Drydock 2024

The ship's last drydocking was in 2024 (November) conducted in Singapore.

The project was for a scheduled (5-year) routine maintenance, including machinery overhauls, standard hotel upkeep, safety inspections, and hull works (blast cleaning/repainting).

Drydock 2018

The ship's first drydock refurbishment was in 2019 (October 19 - November 16) at Singapore's Sembcorp Marine Shipyard.

The USD 65 million drydocking project included general maintenance works, technical overhauls, refreshed interiors and new attractions.

Deckplan changes included two new team gaming experiences - a Laser Tag and an Escape Room.
