Question: Where is Royal Caribbean's MS Radiance of the Seas registered?
Context: MS "Empress of the Seas" is a cruise ship operated by Royal Caribbean International.  She was formerly operated by Pullmantur Cruises as "Empress."  The ship was ordered by Admiral Cruise Lines and was intended to be called the "Future Seas" and join the other Admiral ships, the "Azure Seas" and the "Emerald Seas" .  However, when Royal Caribbean merged with Admiral in 1987, the Admiral brand was dissolved and the newbuild (still under construction) was incorporated into the Royal Caribbean fleet.  A few signature Royal Caribbean brand elements were added, including the Viking Crown and Windjammer Cafe. MS "Freedom of the Seas" is a cruise ship operated by Royal Caribbean International.  It is the namesake of Royal Caribbean's "Freedom" class, and can accommodate 3,634 passengers and 1,300 crew on fifteen passenger decks.  "Freedom of the Seas" was the largest passenger ship ever built (by gross tonnage) from 2006 until construction of the Royal Caribbean International's "Oasis"-class ships in late 2009. MS "Brilliance of the Seas" is a cruise ship belonging to the Royal Caribbean's "Radiance" class.  "Brilliance of the Seas" is operated by RCL UK Ltd., a subsidiary of Royal Caribbean Cruises Ltd. MS "Radiance of the Seas" is a cruise ship owned and operated by Royal Caribbean International.  She is registered in Nassau, Bahamas, and is a gas-turbine vessel, the first built for Royal Caribbean.  This system produces higher efficient speeds than other cruise ships, and emissions to the air are much lower than cruise ships powered by diesel engines. Royal Caribbean International is a cruise line brand founded in Norway and based in Miami, Florida, United States.  It is owned by Royal Caribbean Cruises Ltd.  s of March 2017 , the line is operating 24 ships, has six additional ships on order, and controls 21.9 percent of the cruise market worldwide.  All ships under the Royal Caribbean International brand have names ending with "of the Seas" (e.g. "Empress of the Seas" ) a practice which began in 1991. Vision class is a term Royal Caribbean International uses to refer to six cruise ships operated by themselves and Thomson Cruises.  Although called a "class" by Royal Caribbean, the Vision-class ships were built as three pairs of sister ships.  Each pair differs from the others in size and design, so the six ships do not constitute a single ship-class by the common usage of the term.  The class was further split when "Enchantment of the Seas" was lengthened by 73 feet in 2005.  Unlike other Royal Caribbean classes, the Vision class is not named for the first ship built ("Vision of the Seas" was named for the class, not vice versa). MS "Independence of the Seas" is a "Freedom"-class cruise ship operated by the Royal Caribbean cruise line that entered service in April 2008.  The 15-deck ship can accommodate 4,370 passengers and is served by 1,360 crew.  She was built in the Aker Finnyards Turku Shipyard, Finland, builder of "Freedom of the Seas "and "Liberty of the Seas", her sister ships of the "Freedom "class.  At 154,407 GT, she joined "Freedom of the Seas" and "Liberty of the Seas" as the largest cruise ships and passenger vessels yet built.  She is 1112 ft long, and typically cruises at 21.6 kn .  The vessel operates from Fort Lauderdale, Florida during the Fall and Winter months and Southampton, England during the Spring and Summer months.
