The Vikings were able to effectively use their longboats because of the
following:
- The boats moved swiftly and efficiently in the water making it easy to evade their enemies.
- The longboat rode high in the water, allowing it to sail further in the shallow water and transport the vikings closer to shore.
- The long boat was not only fast, but also light enough to be carried over land fortifying bridges.
Vikings made use of the long boat because it was light weighted and the
people could carry it.
The light weight of the ship also ensured that it moved swiftly and was able
to sail in shallow waters.
