A Shipyard off the River Thames, Deptford , with an Admiralty Yacht & Barge in the foreground
oil on canvas
64.80 x 84.40 cm
The Painting shows a Shipyard & Boat House off the River Thames at Deptford.
The barge in the foreground has the long rudder characteristic of Thames upstream barges as well. The Yard has a lot of stacked Wood in various lengths arranged in the vicinity a phenomena you would expect to see in any busy shipyard of this period.

The ensign might be a St George cross or an white ensign with the red St George in the upper quadrant (which would technically imply 'Royal Naval') this is unlikely since the standard naval form was red unless the vessel was part of a white squadron- which this is not; however if it was a personal property of a flag officer 'of the White' at the time then this may show a Private boathouse of a Flag Officer of the White on the banks of the River Thames.
