Wow this is a nice shot. Compositionally I would have to say that the ship just a tad bit closer to one of the bottom corners would have been a bit more attractive to the eye. Your sky is wonderful. your colors are great. This is a strong shot.
The water is a mucky Blah, but that is not your fault. Looks like things are a bit stirred up out there. Wonderful job.
The center-haters will rate you down a notch or two for the boat's position. But I think it is visually pleasing that way. It's not my kind of beach, but the boat makes it look good to me.
Such marvelous tones here! I'd like to see what would happen if the boat were farther to the right--more rule of thirds orientation. It might make the negative space speak even more loudly of the encompassing world the boat is in.
