Avang, also known asabang orpontin, is a traditional trading ship of theIvatan people of the Philippines. It is the largest boat type among the Ivatan people and characteristically has a closed deck. It is about 14 to 18 m (46 to 59 ft) in length and about 5 m (16 ft) in height. It is slightly curving, with the bow and the stern higher than the central area. It has two masts made from woven mats ofpandanus leaves, though these were later replaced withcanvas cloth (kacha) in colonial times. It also has fifteen pairs of rowers.[1] The avang resembles thevasinian boats of theYami people. Avang are extinct, the last ship was dismantled in 1910.[2]
