A ship class is a group of ships of a similar design. This is distinct from a ship type, which might reflect a similarity of tonnage or intended use. For example, USS Carl Vinson is a nuclear aircraft carrier (ship type) of the Nimitz class (ship class).
27-459: MS Caribbean Princess is a modified Grand -class cruise ship owned and operated by Princess Cruises , with a capacity of over 3,600 passengers, the largest carrying capacity in the Princess fleet until June 2013 when the new Royal Princess , another Princess ship superseded its record. She has 900 balcony staterooms and a deck of mini-suites. Caribbean Princess is slightly larger than
54-531: A NATO reporting name . In addition, the ships of the class would have a number prefixed by a letter indicating the role of that type of vessel. For example, Project 641 had no name, though NATO referred to its members as Foxtrot-class submarines . The ship classification does not completely correspond common designation, particularly for destroyers, frigates and corvettes. Russia has its own classification system for these ships: The British Royal Navy (RN) has used several methods of naming classes. In addition to

The charges related to illegal discharges off the coasts of Florida, Maine, Massachusetts, New Jersey, New York, Rhode Island, South Carolina, Texas, Virginia, the U.S. Virgin Islands and Puerto Rico. As part of the agreement cruise ships from eight Carnival companies, including Carnival Cruise Line and Holland America Line , are required to operate for five years under a court-supervised environmental compliance plan with independent audits and
108-758: A court-appointed monitor. According to the US Justice Department, the fine was the "largest-ever criminal penalty involving deliberate vessel pollution." Caribbean Princess has undertaken cruises from European ports around the British Isles , northern Europe and the Mediterranean and from North American ports to the Caribbean, New England and Canada. The ship in July 2019 left her current home port of Fort Lauderdale, Florida and sailed up to
135-669: A new home port in New York for cruises to Canada, New England, and Greenland. As of 2020, however, the ship sails primarily in the Caribbean. Grand-class cruise ship The Grand class is a class of cruise ships . Ships in the class are operated by the cruise lines Princess Cruises , P&O Cruises , P&O Cruises Australia and Carnival Cruise Line . The class consists of several series (subclasses) of sister ships, most of which were built by Fincantieri in Monfalcone and Trieste, northern Italy . The first vessel of
162-598: A stopover in St. Maarten . The problem caused Princess Cruises to cancel the next two trips (scheduled for 18 and 25 March). Caribbean Princess experienced a norovirus outbreak in January 2014 sickening approximately 200 people on board. The scheduled cruise ended two days early. On 3 August 2016, Caribbean Princess experienced a power outage while on a British Isles cruise. The ship completely lost propulsion about 25 nautical miles (46 km) southeast of Dublin , Ireland in
189-439: A traditional naming system for its ships. In addition, the ship's type and missions can be identified by the first number on the ship's three-digit hull number , which is placed on the front bows and the back of the stern. The naming convention is: Russian (and Soviet ) ship classes are formally named by the numbered project that designed them. That project sometimes, but not always, had a metaphorical name, and almost always had
216-521: Is also the largest ship in the Grand class. The second Ventura -class ship is MS Azura , launched in March 2010 which has a modified stern. Azura is also the only P&O Cruises ship to feature a poolside theater style outdoor screen. Ship class In the course of building a class of ships, design changes might be implemented. In such a case, the ships of different design might not be considered of
243-400: Is the third version of the design and has one additional deck. As in the original Grand -class design, the nightclub is suspended on the stern. Caribbean -class vessels also introduced a poolside theater , which was later added to other Princess ships. The Crown class is the fourth Princess Cruises version of the Grand class and has two additional decks. Crown -class ships have returned
270-526: The Confederate States Navy . Generally accepted by military historians and widely used in the more recent books, webpages and papers on the subject matter (most notably the releases of Osprey Publishing ), these latter-day classifications are sometimes considered "semi-official" (although they are not). Contemporary records, such as the " Official Records of the Union and Confederate Navies in
297-588: The Irish Sea , and was left adrift for nine hours. During the power outage, air conditioners, lighting, hotel functions, and toilets were all functional. The ship regained power and sailed to Belfast , Northern Ireland, missing her next port of Dublin on her itinerary. An ocean-going tug was dispatched from Holyhead in North Wales , UK and an air/sea rescue helicopter from Dublin monitored the situation. The cruise continued without any further problems to either

#1732783042325324-646: The Weapon rather than Tomahawk class. In European navies, a class is named after the first ship commissioned regardless of when it was ordered or laid down. In some cases this has resulted in different class names being used in European and U.S. references; for example, European sources record the Colorado -class battleships of the United States Navy as the " Maryland class", as USS Maryland
351-471: The stern of the ship ( Grand and Caribbean classes) or is located just aft of the funnel (Gem and Crown classes). The Gem class of ships is based primarily on the Grand class, but modifies the placement of the nightclub to be just aft of the funnel and also modifies the number of restaurants. The two Gem-class ships were built by Mitsubishi in Nagasaki , Japan in 2004. The Caribbean class
378-586: The War of the Rebellion " (Series 2, Volume 1, Part 1), show that the modern nomenclature was not in use at the time. The unofficial retro-applying of ship classes can occasionally lead to confusion. For example, while American works consistently adhere to the City - and Columbia -class monikers, works of British origin refer to the same classes as Cairo class and Tennessee class respectively, in compliance with
405-582: The accepted European convention, some classes have been named after a common theme in the included ships' names, e.g., Tribal-class destroyers , and some classes were implemented as an organizational tool, making traditional methods of naming inefficient. For instance, the Amphion class is also known as the A class. Most destroyer classes were known by the initial letter used in naming the vessels, e.g., V and W-class destroyers . Classification by letter also helped to conflate similar smaller classes of ships as in
432-525: The case of the A-class destroyers of 1913 whose names spread across the alphabet. Since the end of the Second World War , Royal Navy ship classes have also been known by their type number (e.g. Type 45 destroyer .) For the United States Navy , the first ship in a class to be authorized by Congress is the designated class leader and gives the name to the class, regardless of the order in which
459-673: The current convention to historical naval vessels sharing similarities, such as those of the American Civil War , where the Union Navy built several vessels in series, which can be termed "classes" as presently understood. Common examples include the Passaic -class monitor and the City-class ironclad , among many others, for the Union side, and Columbia class or Richmond class , for those ironclads in service with
486-661: The modern Royal Navy naming conventions. By the time the United States entered World War II, the current naming convention was in place, though it remains unclear as to exactly how and when the practice originated. Merchant ships are almost always classed by a classification society . These vessels are said to be in class when their hull, structures, machinery, and equipment conform to International Maritime Organization and MARPOL standards. Vessels out of class may be uninsurable and/or not permitted to sail by other agencies. A vessel's class may include endorsements for
513-420: The original Grand class, Grand Princess , entered service in 1998. Ships of the later subclasses are based on the Grand class, but have modifications such as additional decks and varied placement of facilities such as the nightclub and restaurants . The structure used as a nightclub is a signature element of Princess Cruises' ships in the Grand class and derived classes. The nightclub either overhangs
540-553: The other ships in her class ( Star Princess , Golden Princess , and Grand Princess ), due to an additional deck of cabins called the "Riviera" deck. Another difference is that, being initially designed to cruise the Caribbean year-round, there is no sliding roof over the pool area for shelter in poor weather. On 12 March 2012, Caribbean Princess suffered a problem with her port side propulsion engine that required her to return to her home port of San Juan, Puerto Rico after
567-545: The placement of the nightclub adjacent to the funnel. Crown -class ships also feature a poolside theater like the Caribbean class. The Ventura class has 19 decks like the Crown class. These ships both owned and operated by P&O Cruises and are marketed as Grand class, although they were given the Ventura class designation because they are not owned by Princess and are totally modified internally and externally. Ventura

#1732783042325594-399: The same class may be referred to as sister ships . The name of a naval ship class is most commonly the name of the lead ship , the first ship commissioned or built of its design. However, other systems can be used without confusion or conflict. A descriptive name may be used; for example it was decided to group destroyers made to the same design as HMS Tomahawk , all named after weapons, as
621-558: The same class; each variation would either be its own class, or a subclass of the original class (see County-class cruiser for an example). If ships are built of a class whose production had been discontinued, a similar distinction might be made. Ships in a class often have names linked by a common factor: e.g. Trafalgar -class submarines ' names all begin with T ( Turbulent , Tireless , Torbay ); and Ticonderoga -class cruisers are named after American battles ( Yorktown , Bunker Hill , Gettysburg , Anzio ). Ships of
648-419: The ship or the passengers. In 2019, a man in his 30's drowned in a pool aboard Caribbean Princess . On 26 August 2013, the crew of Caribbean Princess deliberately discharged 4,227 US gallons (16,000 L) of oil-contaminated bilge pollution off the southern coast of England. The discharge involved the illegal modification of the vessel's on-board pollution control systems and use of a " magic pipe ", and
675-459: The ships of that class are laid down, launched or commissioned. Due to numbering conventions, the lead ship often has the lowest hull number of its class. (During World War II , the award of construction contracts was not always congruent with completion, so several ships had higher hull numbers than later ships.) Before the 1920s, naval vessels were classified according to shared characteristics. However, naval historians and scholars retro-apply
702-491: Was commissioned before USS Colorado . The West German Navy ( Bundesmarine ) used a three-digit type number for every class in service or in advanced project state. Modified versions were identified by a single letter suffix. After the reunification of Germany the German Navy ( Deutsche Marine ) kept the system. Informally, classes are also traditionally named after their lead ships. The Indonesian Navy has
729-669: Was photographed by a newly hired engineer. When the ship subsequently berthed at Southampton , the engineer resigned his position and reported the discharge to the UK Maritime and Coastguard Agency . An investigation was launched by the United States Department of Justice Environment and Natural Resources Division which found that the practice had been taking place on Caribbean Princess and four other Princess ships since 2005. In December 2016, Princess Cruise Lines agreed to plead guilty to seven felony charges and pay
