I know this resource.
There is it:
http://www.imagico.de/pov/water/water05.php

#declare Material_001 = texture{
    pigment{color srgbft <0.5012,0.9606,0.9037,0.0000,0.0000>}
    finish{
        diffuse 0.8000
        brilliance 1.8000
        specular 1.0000
        roughness 0.0200
          }
normal {
  function {
    f_ridged_mf(x, y, z, 0.1, 3.0, 7, 0.7, 0.7, 2)
  } 0.4
  scale <0.01, 0.4, 0.13>*0.2
}
}

It could be very good! :)
But, there is a problem. It's not clear.
Polygons of a wave are expanded more, than other polygons. Shall be on the
contrary (inverse).

Yes! Thanks.
To my previous post:
The uv_mapping corrects the form, but
To take good result, long time is necessary. :)

crackle -2 ?
That's an extremely strong normal. Try something gentler, like crackle 
-0.2 instead. It should look beter.
Also, you may want to add some turbulence.

Those looks like the ripples caused by a cross wind at the top of the waves.

I took from the file without changes.
I play the whole day with parameters, but I don't find an optimal variant.
I will try to create the ocean in the Blender with the internal render and I
will show what I want to achieve on a large scale.

In the Blender it is possible to make so (look attach).
In Povray so it is impossible to make.
It is necessary to try to bend mesh before export to Povray.
For the static picture there are no problems. For this purpose there is a
'Noise' button.
In case of animation - a problem.

I guess you are talking about deforming a mesh

http://wiki.povray.org/content/User:Le_Forgeron#Getting_a_new_mesh_from_a_mesh

It's not in official povray, but in hgpovray.

Of particular interest, if I got the post right: warp & displace.

I used warp to simulate the wind acting on a flag (moving the reproducible warp a bit
between each frame.
As I was making a cycling animation, the movement was a rotation but any paths would
have do )

Thanks!
I use your version. But, I don't use exclusive options.
What works what doesn't work? There is no time to check and complain. :)))))
Because I receive similar outputs of the console

File '/tmp/Empty.pov' line 8: Parse Error: No matching } in 'texture',
 undeclared identifier 'voronoi' found instead
Fatal error in parser: Cannot parse input.
Render failed

In attachment blender procedural texture "clouds"
But, what equivalent in Povray?
