How did longships help Vikings raid and explore distant places?

The longship was essential to Viking expansion, serving as a versatile, sturdy, and maneuverable vessel that enabled both far-ranging raids and long-distance exploration.12

Key features that facilitated these activities included:

• Design and Construction: These ships were clinker-built with overlapping planks, making them exceptionally sturdy in heavy seas. Their double-ended design allowed them to move forward or backward without turning, which was highly advantageous in narrow waterways or during quick retreats.12
• Propulsion: Equipped with both a square sail and oars, longships could navigate open oceans and shallow coastal waters or rivers. The ability to row allowed Vikings to mount surprise, hit-and-run raids on coastal cities and towns, as they were not solely dependent on wind.123
• Versatility: Because they were essentially large open boats, the same vessels were often used for both trade and warfare. This flexibility allowed Viking groups to transition between exploration, colonization, and pillaging as the occasion demanded.13

These ships carried the Vikings across the Atlantic to Iceland, Greenland, and North America, while also enabling the invasions of the British Isles and continental Europe.13
