The drawing was made with the page turned vertically. It comprises two women with parasols, seen from behind seated on a slope, with what may be a small girl between them. The group and its setting evoke the parties of spectators on the shore below Cowes Castle in the finished painting East Cowes Castle, the Seat of J. Nash, Esq.; the Regatta Starting for their Moorings, exhibited at the Royal Academy in 1828 (Victoria and Albert Museum, London),1 and the 1827 oil Sketch for ‘East Cowes Castle, the Regatta Starting for Their Moorings’ No.3 (Tate N01997).2
Compare in particular the slighter sketch of a bigger group on folio 13 recto (D20615; Turner Bequest CCXXVI 12), where other studies are noted. For more on studies in this sketchbook relating to the regatta events at Cowes from late July 1827 onwards, see the Introduction.
