A sketch showing the tonal effects of light on the surface of the sea, from the 'Castilian'. The sea is shown as pale grey wash with the movement of waves indicated by a series of short brush strokes of varying shades of grey. The bright effect of the sky is indicated by linear washes of lightly toned paint and by an intense reflection on the surface of the water. Everett sailed in the steamer, 'Castilian', from London to the Mediterranean, between October 1937 and February 1938. This was his last journey to sea, probably because of World War II. The painting is inscribed with the artist's monogram bottom right, and 'Cas' verso.
