Dendrochronology has given a likely felling date of 1449 for the majority of the timbers. These came from the Basque region of northern Spain, an area well known for its shipbuilding industry at this time. The ship is thus likely to have been built around 1449, in or close to San Sebastian. Timbers associated with later phases of repair come from Britain, as do a large number of structural pieces dating from c.1466. These timbers have been associated with the major renovation work being carried out in Newport at the time the vessel foundered. Remnants of a cradle found beneath the ship suggested that it had been berthed for repair but then abandoned after the supports on the starboard side gave way. Many of the artefacts in the ship, such as coins, pottery and plant remains, suggest that it was trading with Portugal in the 1450s-60s.
