A Viking ship is a type of vessel used by the Norse people during the late 8th to early 11th centuries. These ships were designed for both ocean travel and navigating shallow rivers, allowing the Vikings to explore, trade, and raid across Europe. Characterized by their long, narrow hulls and symmetrical ends, Viking ships were often made from oak and featured a single mast with a square sail. The most famous type of Viking ship is the longship, which was built for speed and agility. Longships had a shallow draft, enabling them to land on beaches and travel inland. Another type, the knarr, was broader and used primarily for cargo transport. Both ship types played a crucial role in the expansion of Viking culture and influence.
