Soft ocean waves?
 

Hello. Not sure if this is the right place to ask, but I just can not get a smooth surface with ocean shader. I am looking for a setting that will give me a lake with long and soft waves. I have been fiddling around for hours now and the closest I get is something that looks like a flat floor and an occasional ridge every now and then. I just want a simple flow from top to botton like a sine wave. Can somebody please tip me off to a good setting?
