Do you think this picture needs to be cropped?

I took this shot from a cruise ship as we departed Miami. As you can see, I am violating the general rule to not cut the picture in half with the horizon. Do you think I should crop it some? I assume the crop would have to come off the top if I do.

Other pictures I have taken during the cruise can be found here if interested:

Thanks in advance for any comments / suggestions you may have.
