Open Ocean Help!!

I have been trying to make a realistic open ocean and have had little luck. The tutorials on here for close ocean waves or great but I need something on a bit bigger scale. Can anybody help?? It would be much appreciated.

If you haven’t already done so, have a look at the ocean tutorials on Colin Listers web site:
COG Films Ocean Tutorials.

They work from close up to the horizon.
