Viking longships came in many shapes and sizes. The smallest of these was a Karvi.

Karvi were the smallest ships considered suitable for military use. They had between six to eighteen rowing benches and were up to 23 meters long. Considered “general purpose” ships usually used for fishing or trade, they were only occasionally conscripted for military use. The Gokstad Ship, one of the earliest excavated longships, is considered to be a Karvi.
