if you have a compositing program like after effects, you can make multiple layers. have the bottom layer be the waves like you showed. then make another layer, of only the sky. you can cut the sky out in photoshop. if you extend the sky lower and give it a flat bottom, then place it over the ocean, it will appear as if the waves are straight in the distance, when really it's only because the sky layer above it is hiding the tops of the waves.

i hope that makes sense. otherwise if you want to solve the problem in maya, you got me.
