Well, the seaweed doesn't bother me because it's part and parcel of the seaside landscape and matches up nicely with what we see beneath the shallow water. I do like the colors.
I don't like the crop so much of Mathius13's version because it has cut out the play of reflection between the little boat and the larger one. However, I may have cloned out that small patch on the lower right. Also, that B&W has too much mid-tone grey.
I think that one other thing should be addressed IMO. DOF. I think I may have preferred to have the DOF end just past the last boat, having all in focus or either have the last two boats more OOF.
...and that's a mighty large image you have there, sir. ;~)
