Why did the shape of longboats help it to travel quickly?

The shape of longboats, characterized by their narrow hulls and elongated design, allowed them to cut through water more efficiently, reducing drag. This streamlined form enabled them to achieve higher speeds and navigate swiftly through both open seas and shallow waters. Additionally, the lightweight construction and symmetrical design contributed to their agility, making it easier to maneuver in various maritime conditions. As a result, longboats were highly effective for trade, exploration, and warfare.
