Literally, the word pinisi refers to a type of rigging (the configuration of masts, sails and ropes (‘lines’)) of Indonesian sailing vessels. A pinisi carries seven to eight sails on two masts, arranged like a gaff-ketch with what is called 'standing gaffs' - i.e., unlike most Western ships using such a rig, the two main sails are not opened by raising the spars they are attached to, but the sails are 'pulled out' like curtains along the gaffs which are fixed at around the centre of the masts.

As is the case with many Indonesia sailing craft, the word 'pinisi' thus names only a type of rig, and does not describe the shape of the hull of a vessel that uses such sails.

Pinisi-rigged ships were mainly built by the Konjo-speaking people of Ara, a village in the district of Bontobahari, Bulukumba regency, South Sulawesi, and widely used by Buginese and Makassarese seafarers as a cargo vessel. In the years before the eventual disappearance of wind-powered transport in course of the motorization of Indonesia's traditional trading fleet in the 1970/80s, vessels using a pinisi rig were the largest Indonesian sailing ships.
