Creating a lasting record - Photogrammetry of the ‘Barangaroo Boat’
Published

A unique vessel, referred to as the ‘Barangaroo Boat’ was uncovered during construction of Barangaroo Station on Gadigal Country. Archaeologists revealed the almost complete remains of a colonial-built boat, approximately 9 metres long by 3 metres wide, adjacent to a former boatyard.
Possibly one of the earliest surviving European style Australian-built vessel, the museum is proud to be unravelling its many secrets and sharing this sensational find with the world.

Photogrammetric three-dimensional (3D) recording was employed during excavation of the boat to document its surviving hull in situ. Its original archaeological context was recorded as quickly and accurately as possible.
Photogrammetry is the process of obtaining reliable measurements from digital imagery. Overlapping images of an object, structure or space generated from a photogrammetric survey can then be converted into 3D digital models.
3D photogrammetric surveys were carried out at various phases during the excavation and deconstruction of the boat’s hull and show it before and after removal of timbers such as the ceiling planking, framing and keel. This painstaking work has enabled archaeologists to better understand the various components used in the hull’s construction and how they were assembled.
Photogrammetry has also been used to generate accurate and detailed virtual models of each individual hull timber. These in turn have been 3D printed to 1:5 scale and will be used to assemble a physical scale model of the hull. This model will then be used to plan and troubleshoot reconstruction of the actual timbers. Digital 3D models will also be used to reconstruct the boat’s hypothesised original appearance, to suggest what it once looked like and how it sailed.
