Mug - Viking Ship

Viking ships were marine vessels of unique structure, built by the Vikings during the Viking Age. The boat-types were quite varied, depending on what the ship was intended for,[1] but they were generally chraacterised as being slender and flexible boats, with symmetrical ends with true keel. They were clinker built, which is the overlapping of planks riveted together. Some might have had a dragon's head or other circular object protruding from the bow and stern for design, although this is only inferred from historical sources. Viking ships were not just used for their military prowess but for long-distance trade, exploration and colonisation.[2][dubious – discuss] In the literature, Viking ships are usually seen divided into two broad categories: merchant ships and warships. These categories are overlapping; some kinds of merchant ships, built for transporting cargo specifically, could also be used as warships. The majority of Viking ships were designed for sailing rivers, fjords and coastal waters, while a few types, such as the knarr, could navigate the open sea and even the ocean. The Viking ships ranged from the Baltic Sea to far from the Scandinavian homelands, to Iceland, the Faroe Islands, Greenland, Newfoundland, the Mediterranean, the Black Sea and Africa.[3]
