This gallery loads goods from several sunken ships in Indonesian waters from the 9th century to 12th AD. The ship sank and its cargo was sailing from various places in the world and drowned when stopping in the archipelago. Based on the goods found in the ship, can be reconstructed trade routes and transit. Not only that, even the rest of the timber ship can be reconstructed intact form. In the reliefs of Borobudur temple seen the image of a double-dipped sailboat made of wood originating from the 8th century. Usefulness of the outrigger is to balance and stabilize the boat. Single or twin canoeed canoes are typical Austronesian naval boats used in their explorations and deployments in Southeast Asia Oceania and the Indian Ocean. The type of twin crowned boats displayed in Borobudur is most likely the same type of ship used by the Syailendra Dynasty, the Ancient Mataram Kingdom and the Sriwijaya Kingdom that ruled the Nusantara Waters from the 7th to the 13th century AD. The characteristics of wooden ships with Southeast Asia technology are V-shaped hulls, no waterproof seals in the stomach and the entire manufacturing process using boards, fibers, pegs and resin. Shipbuilding technology using bonding and bonding boards (sewn plank and lashed-lug technique). A rectangular or tambuko bulge is used to tie ivory boards and boards.
