Traditional boats of Indonesia, usually called perahu or proa, cover an extremely wide range of sailing craft and date back centuries. The oldest known picture of an Indonesian ship can be seen, carved in stone, on a panel of the Borobudur, the famous eighth-century Buddhist temple in Central Java. This picture basically shows the same built-up hull rigged with tripod masts that can still be seen sailing today. Traditional boats of Indonesia, as they are built today, vary much in shape and size from a simple dug out canoe to large, motorized, cargo boats of over 500 tons of deadweight.
