You’ve got it partially backwards. The sky is blue because of Rayleigh scattering, but it doesn’t reflect the ocean; the ocean is blue because it reflects the sky.
Incidentally, I’ve heard it said (I think it was xkcd) that we use the term “Rayleigh scattering” because it sounds silly to say that the air is blue (via the mechanism of Rayleigh scattering); so maybe that’s part of it?
The bit about the ocean being blue because it reflects the sky is unfortunately mostly wrong. Water is slightly more blue than ozone, so the more of it there is (big water in big ocean) the more blue it will look. The fact that it’s also reflecting the blue sky adds to the color, but on a cloudy day the ocean is still blue.
