Aquatint. Hand-coloured print showing the stern and starboard of the Keying, a large nineteenth century, 160ft (48.8m) Chinese trading vessel with high bow and stern sweeping steeply down to a deep hold. She is tacking upwind against a stiff breeze. Keying has three masts on two of which are hoisted elliptically cut matting sails stiffened wth bamboo battens, seen angled obliquely to catch the wind from starboard. From her mast tops she flies a British flag and also a yellow Chinese flag. Coloured flags and pennants fly from the mast head and stern. The stern-set rudder is fenestrated, the holes in the wood cut to lighten the steering. In the background a small sailing craft is seen against a low coastline and distant windmill, possibly on Windmill Hill at Gravesend which Keying must have passed on her way along the Thames on her visit to London.
