Have some boats. If I understand correctly these would be smaller craft more suitable for rivers, lakes, and coastal waters. Some of them may be more modern then you would like, but dhow, junk and sampan have been around for a long time. Also some, like the junk and dhow had larger versions for the open ocean. Of course that's just what I've gleaned from some online reading, more knowledgable folks please feel free to chime in.
