Painting waves is a real joy. The best part is painting the foam. You can let the paint do the work. The painting technique I use always depends on what I'm painting and when painting foam I can go all the way in using impasto techniques. No need to smooth out my brush strokes (like in for example the blue of the sky). The texture only adds to the dynamic of the wave rolling over.
Because this is an evening scene I get to paint lovely warm accents with lots of paint on my brush. Still, it's not all impasto. Glazing can be very useful here as well. For the shadow part of this wave I used a glaze of transparent white mixed with ultramarine and a bit of sepia. Works great.
But like I said, I'm not a specialist. Maybe you should take a look at the work of a real seascape painter like David Smith (http://davidlyttletonsmith.com).
