[snip] A Borobudur ship is an 8th to 9th-century wooden double outrigger sailing vessel of Maritime Southeast Asia, depicted in some bas-reliefs of the Borobudur Buddhist monument in Central Java, Indonesia.[1] It is a ship of the Javanese people, and derivative vessels of similar size continued to be used in East Java coastal trade at least until the 1940s.[2] [/snip]
