I am sure that this is not an over active imagination. The first photo shows a humpback whale starting a dive not far from our boat. The closeness to the kelp bed and the number of years fishing in the area I know that the water is no over 60 feet (20 meters) deep so the whale cannot dive that deep. In the second photo just to the left of the bow light one can see several small patches of white on the humpbacks pectoral fin as it passes beneath the bow. If you strain hard enough one can see an outline of the whale; we saw it in real time I just hope the camera has captured the image.
