This 3D model documents the preserved stem assembly of the 17th-century Dutch fluyt (fluitschip) Double Dutch (NCN 34303), discovered in 2022 in the intertidal zone of the Wadden Sea near Kornwerderzand by Stichting Archeos Fryslân. The wreck (31m x 6m) was investigated through a series of diving expeditions between 2023 and 2025. Based on constructional characteristics, associated artefacts, and dendrochronological analysis of sampled timbers, the vessel has been dated to around 1680. The stem assembly constitutes an important diagnostic component for the reconstruction of the bow structure and supports the interpretation of the wreck as a Dutch fluyt of approximately 120 Amsterdam feet in length.
