What are the different types of longboats?

Answer 1

According to the sagas and the archaeological evidence, there were basically four important types: The "knarr" was a sturdy trading vessel manned by a crew of +-20. The "Karven" could carry up to 30 people, including more goods, slaves and horses. The "snäcka" (= shell) was sturdier and slower than a longship, but a warship nonetheless. It had 20 benches for rowers, could carry horses and supplies, and was the most common warship. The "longship" is the most fabled of Viking warships. Sleek, narrow and short of draft it could, according to the sagas, carry 100 warriors, and often more.
