Inverted relative to the sketchbook’s foliation, this slight sketch shows yachts approaching north down the River Medina with East Cowes Castle no more than indicated on the skyline at the centre; above is a continuation of the wooded opposite shore around Cowes Castle. Compare the composition of the painting East Cowes Castle, the Seat of J. Nash, Esq.; the Regatta Starting for their Moorings, exhibited in at the Royal Academy in 1828 (Victoria and Albert Museum, London).1 For more on studies in this sketchbook relating to the regatta events at Cowes from late July 1827 onwards, see the sketchbook Introduction; for other views of East Cowes Castle, see under folio 22 recto (D18030), and for Cowes Castle, see under folio 19 verso (D18025).
