Greg,
Unfortunately the moorings are a bit of a red herring here and this is actually an inland location. There is enough information provided to get a reasonable fix and narrow things down considerably.
At the risk of pinning down the size of the body of water and giving the show away, I estimate that the height of the camera was 5 feet and have measured the distance to the shoreline below Fomalhaut as 0.9nm. I haven't tried this myself yet and don't know how well it will work. This is a fairly wide angle view and there might be significant variation in angular scale across the image but as leading advocate for the use of the digital camera as sextant you would know better than I whether this presents a problem,

Regards,
Robin Stuart
