Which consequence arises when Viking longships encounter substantial headwind?

💡 Explanation

Headwinds reduce sail effectiveness by decreasing the forward driving force; the Reaction Force from wind striking the sail is backward, therefore relying heavily on rowing because oar propulsion is less affected rather than benefiting from sail power.
