With a Coolpix, especially at a wide angle setting, the depth of field will be considerable, so there was no chance of blurring the background with this framing. However, I agree with Timoris that the background is not helpful here. With the camera you had with you, the best shot imo would have been at a telephoto setting to get the first boat against the wall, with parts of the other boats of course, and more of the first boat's reflection. I see you have a lot more equipment available now, so if you go back you will have many more options.
