I like the "canvas background" aspect of those houses, they are in a slight haze and therefore look a little unreal to me, which is interesting. The colours of the ropes are so much strong in comparison.
I prefer the composition of the original photo, the quay wall cuts a nice diagonal line through the photo, the heaps of rope have a nice element of repetion and something like a vanishing point, too, in so far as they get smaller and smaller the further they are away.
If I were to consider a crop at all, I'd crop below the numbers 00069 on the boat. The photo feels different then (no more person to be seen, and no "canvas background").
