This ship is the most common trading and voyaging vessel, with some measuring up to 77 ft (23 m). The ship is noticeable and unique in its strengthened and substantial gunwale, which is attached by treenail. Originally, all Beden ships were sewn with coiled coconut fibre, holding the hull planking, stem and stern-post. but Omani variants, beginning in the 20th century, began nailing instead of sewing the planks.
