is it possible to modify the waves so that they occur more often and further out at sea?
Do you mean ripples (appearing in game at the seaside) or real, big waves?
ripples and real big waves :D
OK, so I suggest you to read this update in my MD. (http://sc4devotion.com/forums/index.php?topic=2157.msg105372#msg105372) Ripples can be modified. I did it and showed in that update, i use the modified version from that time (you can see them also in my last updates along all waterfronts). But my intention was to make ripples more smooth, irregular and generally natural. I didn't try to stretch them for - let's say - 200 meters. I can do it, but ripples effect is subtle. Particular white stripes cover partially one to another so they must be less or more condensed. I'm afraid they would be almost invisible if I would stretch it on such large distance...
But I can try and report the result here :D
As for waves - they were provided during SC4 development, but never used in game. I tried to unlock them, but without success, I even made a competition to encourage others to experimenting (look at the end of linked update), but without success too. This theme looks intriguing for me, so I'm sure I will return to it, but I have some more urgent projects now.

it's amazing how much content we can play with and modify ;)
