DAVID W (barge). At the time of seeing her she was not recorded in Lloyd's Register so went down as an unidentified sighting, one of many in my collection. Research has improved in this internet age but, even so, I can find only one passing reference to her/him online.
It appears she was owned by Whitaker and was still in service in 2007 under the name PARAGON.

First vessel leaving the locks at Goole - 27 June 1982: Ron

Whitaker tank barge from their Yorkshire Drydock yard, 1956, 213grt, y.n.22
Later HULL PARAGON then PARAGON, I think in the veg oil trade.
I have her as 'existence in doubt' 1995.

Still in use by Mainmast for oils from Croda to KG dock
