This paper reports on the construction of a full-scale Bronze Age-type sewn-plank boat based on the Ferriby boats. The boat, which was named Morgawr, was constructed in the National Maritime Museum Cornwall in Falmouth, England, during 2012 and the first months of 2013, as part of a larger exhibition in the museum. This paper provides the background and context of the project, describes the process of building the craft, and reflects in particular on differences between Morgawr and the 'hypothetical reconstruction of a complete sewn-plank boat' published in 1990 by Ted Wright and John Coates which formed the basis for this project. © 2014 The AuthorsKey words: National Maritime Museum Cornwall, rocker, withies, keelplank, cleats.T he sewn-plank boats from England and Wales constructed between c.2000 and 800 cal BC are the oldest-known planked vessels from Atlantic Europe. Their construction represents a remarkable development in regional boatbuilding technology. Using planks rather than hides or a hollowed-out treetrunk brought about three concurrent innovations: first, in the absence of any nails or treenails, planks were sewn or stitched together with organic fibres of yew or willow; second, an intricate system of integrated cleats and slots or transverse timbers was employed to ensure stiffness of the bottom of the hull; third, caulking was used for the first time, made from woodland mosses.None of the sewn-plank craft discovered in England and Wales to date are complete or near-complete. The remains of Ferriby 1, the Dover Boat and the Brigg 'raft' are substantial, to the point that their hull shape, size, performance and the seaworthiness of the original craft have generated extensive discussions and debates (for
