How did viking sailors protect them selfs from wind and rain?

Viking sailors protected themselves from wind and rain primarily by wearing layered clothing made from wool and animal hides, which provided insulation and water resistance. They also used cloaks with hoods to shield their heads and faces from the elements. Additionally, their longships featured a raised prow and stern, which helped deflect waves and rain, while the ship's design allowed for some shelter during rough weather. Finally, they often sought to navigate in calmer conditions or sheltered waters when possible.
