The last Thames barge to trade entirely under sail was the Everard-built Cambria in 1970, owned by Captain A. W. (Bob) Roberts. Roberts sailed the Cambria for more than twenty years, and gained a reputation for hard sailing and fast passages in other Everard barges.
Cambria's last mate was Dick Durham from Leigh-on-Sea, Essex, with whom Bob carried the last freight under sail alone: 100 tons of cattle cake from Tilbury Dock to Ipswich in October 1970. Dick wrote Bob Roberts' biography: The Last Sailorman. 
CAMBRIA is a wooden Thames sailing barge, built at Greenhithe, Kent in 1906. She is famed as the last British registered vessel to carry a commercial cargo under sail alone (until 1970) and as such forms a unique part of our industrial and maritime heritage. The barge is owned by a registered charity, the Cambria Trust, established with the specific objective of restoring, preserving and using the famous barge. She is in urgent need of a comprehensive rebuild at a cost of over £1 million.
What will she be used for? Once fully restored, CAMBRIA will be used for sail training and educational purposes, thus preserving the vessels and introducing her to a new audience who will be taught how she traded under sail alone - a supreme example of environmental transport which will also promote an understanding of new alternatives.
What public benefits will be created? Operating as a floating classroom, CAMBRIA will moor at a variety of locations throughout the Thames, Medway and Swale esturaries, offering environmental training and education in social and economic history for Junior school children. Young people and apprentices will take part in sail training and associated activities. CAMBRIA will also operate as a floating museum depicting the history of London River, extending the opportunity to encourage interest and support from the general public.
What has been done to save CAMBRIA? The CAMBRIA was transferred from the Maritime Trust to the care of the Cambria Trust towards the end of 1996 and the barge was in need of urgent care and attention. The hull of the CAMBRIA is now safely housed in the Trust's floating dry dock and the Friends of CAMBRIA have done their best to look after the barge with regular working parties - and limited funds.
A £1 million project The estimates for restoring and bringing sailing barge Cambria back into use are over £1 million. No single body is in a position to fund the full restoration costs and any bid for restoration is dependent upon a successful application to the Heritage Lottery Fund and/or other major funders. An application for funding of £950K was submitted to the Heritiage Lottery Fund in July 2006. The Trust is also working to establish a funding partnership of bodies with a mutual interest in the scheme.
On Monday 21 March, she was re-launched from Faversham for a two month fitting out programme before commencing sea trials and her intended work in support of local schools and social outreach programmes.
