This paper discusses three medieval sewn‐plank reconstructions undertaken in the Sultanate of Oman in the past 40 years: the Sohar, Jewel of Muscat, and al‐Hariri Boat. It describes the specific methods of sewn‐plank construction for each vessel and examines the different methods of documentation applied during the three projects. It concludes with a comparison of the data derived from single‐wadding (al‐Hariri Boat) and double‐wadding (Jewel of Muscat) sewing techniques to highlight the differences between the two methods and emphasize the importance of documenting such reconstructions.
