Definitely different than waterfalls and creeks, but "not really any good" is subjective. I have used it for an interesting effect, but that was years ago. When one clicks the shutter is what can make multiple exposures with medium to big waves interesting . Making the exposures whenever the waves hit rocks, yields an interesting fog around those rocks...especially multiple semi-long exposures (instead of freezing shots). I have a photo of a single rock in the surf zone (multiple long exposures of the waves hitting the rock) -- it made the rock look more like a mountain top sticking out of the clouds.
