This scene was painted above  the Cala Turquetta, in Minorca, and the boat waiting to go out of the cove is the pea green yacht.  The colours are very typical of the area, and there is a lot of contrasting underpainting to achieve the depth of colour of the sea.  I had in my mind at the time a thought of whether to stay safely on the warm sand, or to go out to sea in the waiting boat.
