Krai-longships were large ships resembling giantic multi-oared canoes.They were roofed, as the Sea-Krals hated sunlight and used to sleep or spend the light day beneath deck.Whole families and entire clans spent their entire lifes on these ships.It was unknown how a primitive culture as the Krai was able to built such , quite sophisticated, vessels or even why they did so, as krai were known to hate open water and most often even were unable to swim.
