I like #5 the most. it is not only about the boats, it is also about the environment which the boats are in. I like that they are obstructed, it heightens the sense of place while evoking the feeling of misplacement, abandonment. My only concern is that the boats are not in sharp focus.
I also like #4, but I think that there could have been some other compositional choices here. Still, I like the tension which is evoked for the same kind of reasons listed above - and a harmonious composition would have broken the feeling of misplacement. I prefer the original to the one posted above.
The others I think are a bit humdrum, IMO.
