Question: Treenailed boats were use used by viking in which centuries?

full_context: Document 1: Cork Boat (vessel): Cork Boat is a vessel designed and built by American speechwriter John Pollack and his partner Garth Goldstein. The ship, composed of exactly 165,321 wine corks, took over two years to complete. Over 100 volunteers contributed to the project, and Pollack received numerous donations of materials for it, but most of the corks were provided by Cork Supply USA. Cork Supply USA also paid to ship the boat to Portugal for its trip down the Douro River. The ship looks like a Viking ship, with a pronounced upward curve in its prow. It is made of ten hexagonal logs of corks, each of which is enclosed in netting and made of tens of cork discs. Each disc contains 127 corks, which are held together with large rubber bands. When finished in 2002, Pollack and his friends traveled with their ship down the Douro River in Portugal; his trip received a large amount of media attention. Pollack wrote a memoir about the experience entitled "Cork Boat.
Document 2: Norse–Gaels: The Norse–Gaels (Old Irish: "Gall-Goídil" , Irish: "Gall-Ghaedheil" or "Gall-Ghaeil ", Scottish Gaelic: "Gall-Ghàidheil" , "foreigner Gaels") were a people of mixed Gaelic and Norse ancestry and culture. They emerged in the Viking Age, when Vikings who settled in Ireland and in Scotland adopted Gaelic culture and intermarried with Gaels. The Norse–Gaels dominated much of the Irish Sea and Scottish Sea regions from the 9th to 12th centuries. They founded the Kingdom of the Isles (which included the Hebrides and the Isle of Man), the Kingdom of Dublin, the Lordship of Galloway (which is named after them), and ruled the Kingdom of York for a time. The most powerful Norse–Gaelic dynasty were the Uí Ímair or House of Ivar.
Document 3: Great Heathen Army: The Great Viking Army or Great Danish Army, known by the Anglo-Saxons as the Great Heathen Army (OE: "mycel hæþen here"), was a coalition of Norse warriors, originating from Denmark (and likely also from Sweden and Norway) who came together under a unified command to invade the four Anglo-Saxon kingdoms that constituted England in AD 865.
Document 4: Danes (Germanic tribe): The Danes were a North Germanic tribe inhabiting southern Scandinavia, including the area now comprising Denmark proper, during the Nordic Iron Age and the Viking Age. They founded what became the Kingdom of Denmark. The name of their realm is believed to mean "Danish March", viz. "the march of the Danes" in Old Low German, referring to their southern border zone between the Eider and Schlei rivers.
Document 5: Treenailed boat: The treenailed boat is a boat model used in Northern Europe, usually associated with Vikings but should perhaps be ascribed to Pomeranian groups. The shape and construction coincides with the sewn boats, but instead of ropes, it is assembled with wooden treenails.
Document 6: Viking (ship): Viking is a Viking ship replica. It is an exact replica of the Gokstad ship recovered from Gokstadhaugen, a Viking Era burial mound near Sandefjord, Norway in 1880. The "Viking" was featured at the World's Columbian Exposition at Chicago in 1893.
Document 7: Anglo-Saxons: The Anglo-Saxons were a people who inhabited Great Britain from the 5th century. They comprise people from Germanic tribes who migrated to the island from continental Europe, their descendants, and indigenous British groups who adopted some aspects of Anglo-Saxon culture and language. Historically, the Anglo-Saxon period denotes the period in Britain between about 450 and 1066, after their initial settlement and up until the Norman conquest.
Document 8: Saxons: The Saxons (Latin: "Saxones" , Old English: "Seaxe" , Old Saxon: "Sahson" , Low German: "Sassen" , German: "Sachsen" , Dutch: "Saksen" , Welsh: "Saeson" ) were a group of Germanic tribes first mentioned as living near the North Sea coast of what is now Germany (Old Saxony), in the late Roman empire. They were soon mentioned as raiding and settling in many North Sea areas, as well as pushing south inland towards the Franks. Significant numbers settled in large parts of Great Britain in the early Middle Ages and formed part of the merged group of Anglo-Saxons who eventually organised the first united Kingdom of England. Many Saxons however remained in Germania (Old Saxony c. 531-804), where they resisted the expanding Frankish Empire through the leadership of the semi-legendary Saxon hero, Widukind. Initially, Saxons of Britain and those of Old Saxony (Northern Germany) were both referred to as 'Saxons' in an indiscriminate manner. The term Anglo-Saxon, in turn, came into practice in the 8th century (probably by Paul the Deacon) to distinguish English Saxons from continental Saxons (Ealdseaxe, 'old Saxons').
Document 9: Pinas (ship): The pinas, sometimes called "pinis" as well, is one of two types of junk rigged schooners of the east coast of the Malay peninsula, built in the Terengganu area. This kind of vessel was built of Chengal wood by the Malays since the 19th century and roamed the South China Sea and adjacent oceans as one of the two types of traditional sailing vessels the late Malay maritime culture has developed: The "bedar" and the "pinas".
Document 10: Vikings: Vikings (Old English: "wicing"—"pirate", Danish and Bokmål: "vikinger" ; Swedish and Nynorsk: "vikingar" ; Icelandic: "víkingar" , from Old Norse "víkingar "), were Norse seafarers, mainly speaking the Old Norse language, who raided and traded from their Northern European homelands across wide areas of northern, central and eastern Europe, during the late 8th to late 11th centuries. The term is also commonly extended in modern English and other vernaculars to the inhabitants of Viking home communities during what has become known as the Viking Age. This period of Nordic military, mercantile and demographic expansion constitutes an important element in the early medieval history of Scandinavia, Estonia, the British Isles, France, Kievan Rus' and Sicily.
Document 11: Havhingsten fra Glendalough: 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.
Document 12: Svinfylking: The Svinfylking, Old Norse for 'Swine Array' or 'Boar Snout', was a version of the wedge formation used in Iron Age Scandinavia then by the Vikings, and by the Germanic peoples during the Germanic Iron Age where it was known as the "Schweinskopf" or 'Swine's Head'. Its invention was attributed to the god Odin.
Document 13: Viking ship replica: 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.
Document 14: Proto-Norse language: Proto-Norse (also called Proto-Scandinavian, Primitive Norse, Proto-Nordic, Ancient Nordic, Ancient Scandinavian, Old Nordic, Old Scandinavian, Proto-North Germanic, North Proto-Germanic or Common Scandinavian) was an Indo-European language spoken in Scandinavia that is thought to have evolved as a northern dialect of Proto-Germanic in the first centuries CE. It is the earliest stage of a characteristically North Germanic language, and the language attested in the oldest Scandinavian Elder Futhark inscriptions, spoken around from the 2nd to 8th centuries (corresponding to the late Roman Iron Age and the Germanic Iron Age). It evolved into the dialects of Old Norse at the beginning of the Viking Age in about 800, which later themselves evolved into modern North Germanic languages.
Document 15: Oseberg Ship: The Oseberg ship (Norwegian: "Osebergskipet") is a well-preserved Viking ship discovered in a large burial mound at the Oseberg farm near Tønsberg in Vestfold county, Norway. This ship is commonly acknowledged to be among the finer artifacts to have survived from the Viking Era. The ship and some of its contents are displayed at the Viking Ship Museum at Bygdøy on the western side of Oslo, Norway.
