This model presents part of the keel and floor timber assembly of the 17th-century Dutch fluyt (fluitschip) Double Dutch (NCN 34303), recorded during photogrammetric survey in 2025. As a principal structural element of the ship’s bottom construction, this assembly provides significant information on building sequence, framing arrangement, and hull architecture. The wreck (31m x 6m) , located near Kornwerderzand in the Dutch Wadden Sea, has been provisionally dated to c. 1680 on the basis of dendrochronological evidence and associated material culture. In conjunction with the vessel’s recorded dimensions and other constructional features, this element reinforces the identification of the wreck as a two-deck Dutch fluyt.
