Here's is the setup. I set the wave info of the water shader to zero for roughness, wave scale, and smallest scale. I added a power fractal set to ridged noise with 6.25 for the scale and displacement. The distance shader is added to the Blend by input of the power fractal. The render camera is the center location of the spherical influence of of the distance shader. I then just did some quick renders to set the distance; 10000+ may be a little far...
