Query: What was the largest Viking ship?
Draken Harald Hårfagre (English: Dragon Harald Fairhair) is a large Viking longship built in the municipality of Haugesund, Norway. Draken Harald Hårfagre brings the seafaring qualities of a warship from the old Norse sagas to life. It is a ship that combines ocean-crossing sailing capabilities with a warship's use of oars.
The 5-cent stamp has for its central design a Viking ship. This design is from a photograph of "Viking" which sailed from Norway to Chicago for the Columbian Exposition of 1893. The design on the 5-cent stamp was from a photograph of an exact size replica of "Viking". A flag of the United States is seen waving from the bow of the ship. That ship was a replica of the Gokstad ship on display in the Viking Ship Museum in Oslo. 
The Gokstad ship is a 9th-century Viking ship found in a burial mound at Gokstad in Sandar, Sandefjord, Vestfold, Norway. It is currently on display at the Viking Ship Museum in Oslo, Norway.
It is the largest preserved Viking ship in Norway.
Furthermore, during the early Viking Age, oar ports replaced rowlocks, allowing oars to be stored while the ship was at sail and to provide better angles for rowing. The largest ships of the era could travel five to six knots using oar power and up to ten knots under sail.
One question about Sebber Priory has always been why it was located on the coast in such an isolated location. It appears that Sebber was already a village in Viking times, a trading place for ships plying the Limfjord between the North Sea and the Baltic. Recent research by the Aalborg History Museum has discovered no fewer than three churches on or around St Jørgens Bjerg: two stave churches and a stone one. Over 300 Viking age graves were found in one of the largest Viking cemeteries found to date on the same ground as the priory was built. It seems that Sebber has been historically a religious place, perhaps even in pre-Christian times. If locals were looking for a sacred spot, what better choice on Sebbersund than where the ancestors both pagan and Christian had worshipped.
Viking is a Viking ship replica. It is an exact replica of the Gokstad ship recovered from Gokstadhaugen, a Viking Era burial mound in Sandefjord, Norway in 1880. "Viking" was featured at the World's Columbian Exposition at Chicago in 1893.
On 29 June 1980 "Viking Sally" was delivered to Rederi Ab Sally, Finland and was put into service on the route between Turku, Mariehamn and Stockholm (during summer 1982 on the Naantali–Mariehamn–Kapellskär route). She was the largest ship to serve on that route at the time. As with many ships, "Viking Sally" suffered some mishaps during her Viking Line service, being grounded in the Åland Archipelago in May 1984 and suffering some propeller problems in April of the following year. In 1985 she was also rebuilt with a "duck tail". 
Rederi Ab Sally had been experiencing financial difficulties for most of the 1980s. In late 1987, Effoa and Johnson Line, the owners of Viking Line's main rivals Silja Line, bought Sally. As a result of this, SF Line and Rederi AB Slite forced Sally to withdraw from Viking Line. "Viking Sally" was chartered to Rederi AB Slite to continue on her current traffic for the next three years.
The rediscovery of the Viking past began in Norway during the 19th century when Norway saw a rise in nationalism. Having been in a personal union with Denmark under the Danish king for 400 years and subsequently in the union between Sweden and Norway under the Swedish king, Norwegians started looking back to their Viking era kings and sagas. In 1867, the first Viking ship to be unearthed, the Tune ship, was excavated in Østfold, Norway. The ship provided new knowledge about the Vikings and their culture. The excavation of other ships and artifacts led to a higher consciousness about the Viking past in Norway. For example, the only complete Viking helmet ever to be found was also excavated in Norway.
MV "Viking Star" is the lead ship of the "Viking Star" class of cruise ships, and the first such ship operated by Viking Ocean Cruises, a division of Viking Cruises. She entered service in April 2015. Two "Viking Star"-class sister ships, and , joined her in the Viking Ocean Cruises fleet in 2016.
Viking ship replicas are one of the more common types of ship replica. "Viking", the very first Viking ship replica, was built by the Rødsverven shipyard in Sandefjord, Norway. In 1893 it sailed across the Atlantic Ocean to Chicago in the United States for the World's Columbian Exposition. Formerly located in Lincoln Park, Chicago, Illinois, the "Viking" is currently undergoing conservation in Geneva, Illinois, United States.
Vestfold is the county in Norway with the most traces from the Viking Age. Examples include the Oseberg- and Gokstad Burial Mounds. While the Oseberg Ship was discovered in Tønsberg, the Gokstad Ship was discovered in Sandefjord. The Gokstad Ship is Norway's largest preserved Viking ship. Both ships are now located at the Viking Ship Museum in Oslo. Additional burial mounds are found at Borre mound cemetery and Mølen, an UNESCO Global Geopark. Borre mound cemetery is home to Northern Europe's largest burial mound site from Viking Age.
In 2000, Viking purchased KD River Cruises of Europe, which brought Viking's fleet total to 26, making it the largest river cruising fleet in the world. The company revamped the ships, aiming for its target demographic of older North Americans who wanted to see the world simply; the lack of frills like gyms and pools, and the standardization, also maximized the number of people the ships could accommodate and Viking's profit. The company also partnered that year with sales agents in the UK, and the US, and opened its own sales office in California. It hired its first marketing firm the next year, focusing on North America. The company expanded into China in 2004 with Yangtze River cruises. By 2007 it was operating 23 ships in Europe, Russia, and China. In 2009, Viking started to use ships with hybrid diesel-electric engines that the company said use an estimated 20% less fuel than conventional engines.
SS "Viking" was a wooden-hulled sealing ship made famous by its role in the 1931 film "The Viking". During her use in the seal hunt in Newfoundland, the ship was commissioned by the film crew. During production, an explosion destroyed the ship, resulting in the largest loss of life of a film production crew in film history.
In 1881, "Viking" was built by the Nylands Shipyard at Christiania, Norway, the same location where another famous Newfoundland vessel, "Southern Cross", was constructed. "Viking" was a vessel of 310 gross tons and equipped with a auxiliary engine. She was launched in 1882 from the Nylands Shipyard.
The 9th century Gokstad Ship was discovered in Sandefjord during an 1880 excavation led by Nicolay Nicolaysen. The ship itself, which is now at the Viking Ship Museum in Oslo, was built around year 910. It is the largest preserved Viking ship in Norway. A Viking chieftain was buried at the Gokstad Mound (Gokstadhaugen), along with the 23.5-meter Gokstad Ship. Interpretive signs have been put up at the Gokstad Mound on Helgerødveien.
The Viking Ship Museum overlooking the inlet of Roskilde Fjord was built in 1969 with the main purpose of exhibiting the five newly discovered Skuldelev ships. In the late 1990s, excavations for the shipyard expansion of the museum uncovered a further 9 ships from the Viking Age and early medieval period. It is the largest discovery of prehistoric ships in Northern Europe and includes the longest Viking warship ever found; the "Roskilde 6" at 36 metres. The excavations are not yet completed.
The museum is most famous for the completely whole Oseberg ship, excavated from the largest known ship burial in the world. Other 
main attractions at the Viking Ship Museum are the Gokstad ship and Tune ship. Additionally, the Viking Age display includes sledges, beds, a horse cart, wood carving, tent components, buckets and other grave goods.
Sandefjord has been inhabited for thousands of years. Excavations indicate that people have inhabited Sandefjord for around 3,000 years. Rock carvings at Haugen farm by Istrehågan in Jåberg are dated to 1,500-500 BCE. Haugen farm is home to Vestfold County's largest petroglyph site. The Vikings lived in Sandefjord and surrounding areas about 1,000 years ago, and numerous Viking artifacts and monuments can be found in Sandefjord. One of the most important remains from the Viking age was found at the grave site "Gokstadhaugen" (Gokstad Mound) in Sandefjord. The Gokstad ship was excavated by Nicolay Nicolaysen and is now in the Viking Ship Museum in Oslo. The "Viking", an exact replica of the Gokstad ship, crossed the Atlantic Ocean from Bergen to be exhibited at the World's Columbian Exposition in Chicago in 1893. A replica of Gokstad ship, called "Gaia", currently has Sandefjord as home port. Other known replicas include the "Munin", (a half scale replica) located in Vancouver, Canada.
While naval Viking battles were not as common as battles on land, they did occur. Viking ships would often try to ram ships in the open sea. They propelled the boats by rowing fast directly at defending ships that were vulnerable and isolated from their fleet. To combat this, defending fleets would raft up with the bows of their boats facing the attacking Vikings. Depending on the size of the defending fleet, the Viking ships allowed them to maneuver their boats by rowing around such ships to flank them. When they got close enough, Vikings would throw spears and use their longbows. Archers would be positioned in the back of the ships protected by a shield wall formation constructed in the front of the ship. If the Vikings were attacked while in the water they would wait until they were in fighting distance, then group together to create one long line of boats, which made it easier to move between boats and made their formation more compact.
The majority of the burials discovered were cremations, although a number of inhumations were also discovered, and it appeared that the tendency towards cremation or burial depended upon the period, cremation supplanting inhumation in the Viking Age. The pre-Viking Age burials were under mounds. Of the later graves, some women's graves appear to be distinguished by placement of rocks in a circle or oval, but most of the graves are marked with rocks either in a triangle or in the traditional shape of a boat (stone ship), indicating the importance that the Vikings placed upon water. The ship settings constitute the largest assemblage of well-preserved examples extant. The shape and size of the grave outline apparently indicate the status of the person – all of which is reminiscent of the ship burials of the Anglo-Saxons, Norwegian and Swedish Vikings and other ancient Germanic societies.
Havhingsten fra Glendalough ("The Sea Stallion from Glendalough" or just "Sea Stallion") is a reconstruction of "Skuldelev 2", one of the Skuldelev ships and the second-largest Viking longship ever to be found. The original vessel was built in the vicinity of Dublin around 1042, using oak from Glendalough in County Wicklow, Ireland, hence the ship's name. The reconstruction was built in Denmark at the shipyard of the Viking Ship Museum in Roskilde between 2000 and 2004 and is used for historical research purposes. 
MV "Viking Sky" is a cruise ship operated by Viking Ocean Cruises. "Viking Sky" is the sister to three ships, , , and , and was delivered on January 26, 2017. The ship was planned to set sail in 2016 as "Viking Sea", but delayed until 2017. The ship was christened in June 2017 at Tromsø.
Tønsberg is the site of Oseberg Mound, a Viking era burial mound. The Oseberg Ship was found in the Oseberg burial mound in 1904. This Viking era longship is now in the Viking Ship Museum in Oslo. Archaeological excavations in 1904 uncovered history's largest and richest example of craftsmanship from the Viking Age. In addition to the Oseberg Ship, Oseberghaugen contained the Oseberg carriage, five beautifully carved bed-posts shaped like animal heads, four sledges, beds, chests, weaving-frames, household utensils and much more. Scientific examinations in 1992 now date the burial to 834 AD, and indicate a probability that it was Queen Alvhild, the first wife of King Gudrød, who was buried here.
Myklebustskipet is the remains of a burned Viking ship that was found in a burial mound in the farm Myklebust in Nordfjordeid, Norway. Only the nails are intact, but from the number of the nails the ship may have been at least 25 meters long, perhaps the largest Viking ship that has been found in Norway so far. There were found sound stitches, mastering and a lot of shields in the burial mound, which was excavated in 1874 by the archaeologist Anders Lorange.
Skepplanda is actually located in an area where lots of traces from the time of the Vikings have been found. On a hill, called Stugåsberget, in the woods of Skepplanda, a rock carving of a ship can be found. This is the largest rock carving of the county and depicts a ship and a sun wheel. The sun wheel is also common in Bohuslän and is a symbol for sun worship.
Except for the stone carving, traces from what is believed to be a Viking ship has been found.
Our knowledge of Vikings in Iberia is mainly based on written accounts. There are archaeological findings of what may have been anchors of Viking ships, and some shapes of mounds by riversides look similar to the Norse longphorts in Ireland. These may have been ports or docks for Viking longships.
