Having got the wave painted to my satisfaction, I then started adding some floating foam to the foreground (see also: Sea Painting: Understanding Foam).
The first stage in this looks rather like strands of spaghetti (Photo 9) splattered on the painting. Once that was painted, I followed it with some thicker foam (Photo 10).
But I was working on the floating foam, I decided the right-hand edge of the breaking wave was too uniform, and added some more foam to it.
