I do believe that there is or was a Nessie and other cryptids that could be or could have been different things at different times. Perhaps there was or is a large plesiosaur creature there at times and out in the greater ocean. Perhaps at other times she was or is a large eel. Unidentified swimming objects are interesting and folks could be seeing different things at different times.
After searching about a little more, I think it is a boat wake and an image that has been blurred or overlapped and altered in some way. I believe this image comes from Apple Maps.
I just found this image on Google earth in the same Loch Ness but further up into the river. It has almost the same exact looking wake with two fin-like and a tail-like wake however this image definitely has a boat above the wake.
Perhaps the Apple Map image was just an unfortunate image altering do to the overlapping of images or ghosting as previous posters suggested or perhaps it was a willful removal of the vessel from the image.
