Thanks!

Yeah, I know. I thought about that, but I wasn't sure how water was
supposed to function at the shore. Also I was happy to get it work the
way it does now (flattening out at the edges) so I let it be. I guess
I'll try to fix the waves first and the have a look at this.

Well, it was actually supposed to be wind (I know it doesn't look like
that).
