When i first viewed the image, my eye was searching all over the place, with the whole lot of clutter and distractions in the top third of the image, which also was bland in colour. I found this uninteresting and unappealing. The bottom 2/3rds of the image - the reflection - however, I found to be dynamic and representative of the contrasts of both stillness and movement when on the ocean. This is indicated by the wave like reflections of the masts on the water. The abstract shapes are so fluid and intersting. I felt a sense of serenity, yet an awareness of the power of the waves on the ocean, when so much movement can result even with the smallest of seas.
I would centre the image around the red fender and crop out the right accordingly. I would also crop along just below the door heads on the lower deck to remove the clutter on the upper boat.
I wouldn't level the water...., because when the right side is cropped out, only a small amount of water is left, which then does not give any indication that the water line is not horizontal. The boat which is not horizontal, and without the reference of the extended water line, helps create the movement in the image, and is reminiscent of the rocking and swaying inherent on boats - even when moored. I think that making the boat horizontal would make the image more static and solid, rather than creating the feel of being on the sea.
