What was the common size of a crew on a viking longship?

The common size of a crew on a Viking longship typically ranged from 20 to 60 men, depending on the ship's size and purpose. Smaller vessels used for coastal raiding might have fewer crew members, while larger longships designed for ocean voyages could accommodate more. The crew included not only oarsmen but also warriors and navigators, essential for both combat and travel. Overall, the composition and number of crew members reflected the ship's specific mission and the resources available to the Viking leader.
