Drawn with the pages turned horizontally, the studies continue on folio 77 recto opposite (D05053; Turner Bequest LXXXI 151). Spirited studies of sailing boats in this vein occur on folios 73 verso, 74 verso and 75 verso (D05046, D05048, D05050; Turner Bequest LXXXI 144, 146, 148). Those on D05048 and D05053 are related to the painting Calais Pier, with French Poissards Preparing for Sea: An English Packet Arriving, exhibited at the Royal Academy in 1803 (National Gallery, London).1
