How are Longships different from boats that are used today?

Longships, used by the Vikings from the 8th to 11th centuries, differ from modern boats primarily in their design and purpose. They were long, narrow vessels with a shallow draught, allowing for speed and maneuverability in both open seas and shallow rivers. Unlike many contemporary boats, which often prioritize comfort and stability, longships were built for raiding, trading, and exploration, featuring a single sail and multiple oars for propulsion. Additionally, their clinker-built construction, characterized by overlapping planks, contrasts with the more uniform hull designs seen in today's boats.
