The seventh-century AD boat was found in 2008 and is currently displayed in situ after being treated in a lengthy conservation process. The Punjulharjo boat offers an invaluable evidence for un- derstanding ancient boatbuilding technologies in the region and to help in the interpretation of previous incomplete finds and future discoveries. The proposed paper presents the preliminary results of the first 3D photo- grammetry of the boat, conducted with the aim to analyse and examine in detail the characteristics of the hull from a renewed perspective. The 3D model ob- tained from the photogrammetry was combined with in situ observations and close examination of the hull, as well as with results from previous archaeological investigations of the boat. Over a decade the boat condition has been altered from when it was initial- ly unearthed, the present research contributed to understand the current state of the boat, and to explain hull changes occurred during the depositional process and after the restoration. Such analysis of the hull also aims at a future hypothet- ical digital reconstruction of the boat. The research also assesses the reliability of the approach in general, ap- plied to the study of ancient and contemporary ships and boats in Indonesia, where the documentation method is mostly still rudimentary, to propose future plans for this research.
