[1]: 151 For their war fleet, the Malays prefer to use shallow draught, oared longships similar to the galley, such as lancaran, penjajap, and kelulus.
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.
One distinguishing feature from the galley is the presence of an elevated fighting platform (called a balai), in which warriors usually stood and perform boarding actions.
[9]: 212 According to Afonso de Albuquerque, during the 1511 Portuguese attack on the Malacca Sultanate, the Malays used an unspecified number of lancaran (lanchara) and twenty penjajap (pangajaoa).
[9]: 212 During the Demak Sultanate attack on Portuguese Malacca of 1512–1513, lancaran were used as armed troop transports for landing alongside penjajap and kelulus, as the Javanese junks were too large to approach the shore.
In the 1520s, smaller lancarans of Bintan and Pahang were armed with only 1 berço (breech-loading swivel gun, likely refers to cetbang), but also had arrows, spears, and fire-hardened wooden spars.
