Seems like you took on several challenges simultaneously. Bright sun, the goal of providing some soft blurring of the water, preserving highlights, preserving detail.
If your goal is to smooth the water with a long exposure image and shoot in brighter skies, you really need an ND grad filter to reduce the light entering the sensor. And, depending on the smoothness you want in the water, a longer shutter speed as well.
There is a softness in the broken pilings suggesting camera shake or a focus much further into the scene. I can tell for sure which. Did you use a tripod?
Unfortunately the whites are blown in the posted image, with no detail at the breaking wave close to the shoreline. Maybe there is some recovery possible from a RAW version.
The colors look a bit dull and off to me. I am wondering if this is a style choice you made.
BTW, images are best posted 800 on the long end, although most of us can readily view a 1000 pixel wide image without scrolling.
