Do you need to crop for some reason? Aesthetically, you don't want your subject right in the middle, but if you want to keep all of the ocean you can. If you do want/need to crop, two suggestions. First, I would take off the right 1/4 of the picture to place your subject in a good place. If you prefer taking a little off the other side, I would go only to the far left side of the end of the pier, to still illustrate the pier without feeling like you're cutting off the ocean. You could do both of these if you're looking for a smaller picture. I would leave the height alone unless you need to crop it, and then take off from the bottom, but I would leave some of your husband's jeans or he'll look odd. If that doesn't make sense, let me know and I'll try to be clearer.
