Why were viking longboats good for sailing in shallow water?

Viking longboats were designed with a shallow draft, allowing them to navigate in shallow waters that deeper vessels could not access. Their narrow hulls and lightweight construction made them agile and capable of quick turns, essential for maneuvering in rivers and coastal areas. Additionally, the long, slender design enabled them to travel swiftly and efficiently, making them ideal for raids and exploration along Coastlines and inland waterways. This versatility contributed to the Vikings' success as seafarers and explorers.
