How did sailors in Viking times protect themselves from wind and rain?

Vikings protected themselves from wind and rain primarily by wearing cloaks made of wool or animal hides, which were effective at repelling moisture. They also constructed their ships with high sides and a sturdy hull to shield against harsh weather. Additionally, they utilized tar and oil to waterproof their vessels, ensuring that they remained relatively dry during their voyages. This combination of clothing and ship design enabled them to navigate the challenging maritime conditions of their time.
