This photo shows Dr Katherine Abbass and myself, with the waters of Newport Harbour in the background, where she has the RIMAP team (all volunteers) diving on wreck sites in search of what may be left of Endeavour. I spent a very interesting couple of hours with her during a visit to the area in September, 2001, and she went over the historical events that led to the scuttling of the Lord Sandwich, and her rationale for identifying this ship as Cook's Endeavour. They have finished diving on one site, having found only the remains of smaller vessels.
She has checked sources in London and found records of the Admiralty paying an agent, one Wilkinson, for several of the other scuttled ships, but not the Lord Sandwich; it is just possible, but unlikely, that this hulk was refloated, and disposed of elsewhere. She would like to know more about Wilkinson, a Quaker from Whitby. He is mentioned in Endeavour Lines, number 36, May 2001, page 7. This article is a very clear summary of Abbass's rationale.
