Viking ships were long, narrow vessels designed for speed and agility. They were built using overlapping wooden planks, a technique called clinker construction, which made them strong yet lightweight. These ships had a shallow draft, allowing them to navigate both open seas and shallow rivers, making them ideal for exploration, trade, and raiding. The most famous type of Viking ship is the longship, characterized by its symmetrical ends and a single mast with a square sail. This design enabled the Vikings to travel vast distances, reaching as far as North America and the Mediterranean, showcasing their advanced shipbuilding skills and seafaring abilities.
