The profile of a headland and woods at the top, combined with the two busy studies of shipping inverted relative to it below, including the hatched, silhouetted hull of a large, moored warship, appear to have informed the contre-jour painting Shipping off East Cowes Headland, of 1827 (Tate N01999),1 showing the mouth of the Medina Estuary looking east from the shore at Cowes into the low morning sun.
Turner has made visual and written notes of clouds, colour and tone in the drawing, which correspond with the effects in the painting. Compare the slight sketch of a headland on folio 19 verso (D18025). For more on studies in this sketchbook relating to the regatta events at Cowes from late July 1827 onwards, see the sketchbook Introduction.
