Phinisi, also known as Phinisi, Phinis, Pinis, or Penisch, are traditional Indonesian sailing vessels that predate the 15th century. The term 'Pinisi' likely originates from the European word 'pinnace', describing a small sailing craft. These boats, noted for their masts and sails, were influenced by colonial-era Dutch and other Western vessels observed in Indonesian waters.

Originally constructed by the Konjo boat builders of Bulukumba in Southern Sulawesi, Pinisi were primarily crafted from teak and ironwood, locally known as Kayu Ulin. These boats featured two masts and seven to eight sails and were uniquely built on the beach as a symbol of community unity. Unlike modern boatbuilding, Pinisi construction followed an organic process called "following the wood," where planking was completed before framing, using pasak (wooden pegs) to fasten the planks without a formal blueprint.

Since the 1970s, Pinisi have undergone significant transformations with the introduction of motors, which altered their traditional appearance, masts were shortened or removed, and deck structures were expanded to accommodate crew and passengers. In December 2017, UNESCO recognized the cultural significance of this traditional boat-building technique. Today, Pinisi have been adapted into luxurious yacht charter boats for tourism and recreation, continuing to sail the ancient spice trading routes once used for transporting spices and textiles.
