Hi Mark,
Wow, this is very nice. All of those different shades of blue surrounding the the wide white ship are quite striking. Several have beat me to the punch but I noted the symmetry as well, very effective. The ship also looks sharp, in spite of the haze. Great shot, well done!

I agree about the symmetry and would add that I like the sense you get of all that weight in the water. Good sense of distance too with the slight haze. Nigel
