This sketch is largely a sky study with swift jottings of cloud formations and notes on the colours and tones of light: ‘Dun’ or ‘Warm blue’ for example. Turner has produced a further study of the same sky on the folio opposite (Tate D19899; Turner Bequest CCXVI 174). Rendered in the distance is a diminutive profile of Ostend harbour, with the conical spire of the Peperbusse or St Peter’s Tower visible. Turner produced this sketch and that on Tate D19897; Turner Bequest CCXVI 173 as he approached the Flemish port on 7 September.
