There is circumstantial evidence that by 1469 the ship may have belonged to and been under repair for the Earl of Warwick (Warwick the Kingmaker). A letter of authorisation dated 22 November 1469 from Warwick to Thomas Throkmorton, his receiver of Glamorgan and Morgannwg, authorised various payments for "the making of the ship at Newport" which could be construed as repairs to the badly damaged vessel. Recent research has shown that Newport sometimes had some very large vessels in the fifteenth and sixteenth century, like the Newport Medieval Ship. These were used primarily to serve the long-distance trade of Bristol, which was then the second port of the realm.
