A Borobudur ship is the 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.  It is a ship of Javanese people, derivative vessels of similar size still survived in East Java coastal trade at least until the 1940s. 
The characteristics of the ships of the Borobudur temple include: Having outriggers that are not as long as their hulls, bipod or tripod mast with a canted square sail (tanja sail), a bowsprit with a spritsail, rowing gallery (where people row by sitting or standing), deckhouse, have oculi (carved/bossed eyes), and quarter rudders. Some ships are depicted with oars, numbering at least 6, 8, or 9, and some others have none.

Indonesian Esoteric Buddhism or Esoteric Buddhism in Maritime Southeast Asia refers to the traditions of Esoteric Buddhism found in Maritime Southeast Asia which emerged in the 7th century along the maritime trade routes and port cities of the Indonesian islands of Java and Sumatra as well as in Malaysia. These esoteric forms were spread by pilgrims and Tantric masters who received royal patronage from royal dynasties like the Sailendras and the Srivijaya. This tradition was also linked by the maritime trade routes with Indian Vajrayana, Tantric Buddhism in Sinhala, Cham and Khmer lands and in China and Japan, to the extent that it is hard to separate them completely and it is better to speak of a complex of "Esoteric Buddhism of Mediaeval Maritime Asia." Many key Indian port cities saw the growth of Esoteric Buddhism, a tradition which coexisted alongside Shaivism.

A lancaran or lanchara is a type of sailing ship used in Maritime Southeast Asia. Although similar in shape to Mediterranean galleys, the lancaran was the backbone of the regional fleet of the western half of Nusantara before Mediterranean influence came. For their war fleet, the Malays prefer to use shallow draught, oared longships similar to the galley, such as lancaran, ghurab, and ghali. This is very different from the Javanese who prefer long-range, deep-draught round ships such as jong and malangbang. The reason for this difference is that the Malays operated their ships in riverine water, sheltered straits zone, and archipelagic environment, while the Javanese are often active in the open and high sea.
The djong, jong, or jung is a type of ancient sailing ship originating from Java, Indonesia that was widely used by Javanese, Sundanese, and later Malay sailors. The word was and is spelled jong in its languages of origin, the "djong" spelling being the colonial Dutch romanization.

Ghurab or gurab is a type of merchant and warship from the Nusantara archipelago. The ship was a result of Mediterranean influences in the region, particularly introduced by the Arabs, Persians, and Ottomans. For their war fleet, the Malays prefer to use shallow draught, oared longships similar to the galley, such as lancaran, ghurab, and ghali. This is very different from the Javanese who prefer long-range, deep-draught round ships such as jong and malangbang. The reason for this difference is that the Malays operated their ships in riverine water, sheltered straits zone, and archipelagic environment, while the Javanese are often active in the open and high sea.
Ghali, gali, or gale are a type of galley-like ships from the Nusantara archipelago. Several native galley-like ships already existed in the archipelago, some with outriggers. The design of ghalis is the result of the impact made by Mediterranean shipbuilding techniques on native shipbuilding, introduced particularly by Arabs, Persians, Ottoman Turks, and Portuguese. The terms may also refer to Mediterranean vessels built by local people, or native vessels with Mediterranean influence.
SamudraRaksa is a replica ship built in 2003 based on the relief of ships in the Borobudur temple. In the late 20th century, Philip Beale, a British sailor, became interested in depictions of the ship at Borobudur and decided to reconstruct one. Aided by government and international bodies, he organized an expedition team that constructed the ship and, from 2003 to 2004, sailed it from Indonesia to Madagascar and to Ghana, proving that long-distance trade could have occurred. The Samudra Raksa Museum was constructed at Borobudur Archeological Park to house the ship, opening in 2005, and provides other displays to interpret the ancient maritime history of Indonesians.
