Manuel Huezo submitted this image taken with a Canon Rebel XS, with an exposure of 1/3200sec at f/5.6, ISO 100. Consider cropping some off the bottom, bringing more attention to the boat by moving it out of the horizontal center. The two faces are underexposed so adjust your settings to allow more detail which is important to a quality black-and-white. Giving some thought to the position of the sun relative to the boat, consider catching the scene from the other side of the boat. The tide coming in creates a nice line to lead you viewers across the photo but go ahead and straighten the horizon. This is a nice start, just pay attention to the details.
