GeoGraph - photograph every grid square

I'm not sure where the ship is other than to speculate that it is in an 'all at sea' square so I've located this submission in the viewpoint square. Again I'm not sure but I suspect the lighthouse is at Battery Point at ST464776. If anyone knows otherwise please feel free to correct it. As to the ship it is probably a container ship. It would appear to be on the way into Avonmouth. It seems to be riding quite high in the water. I've never seen the Bristol Channel any other colour than this rather dull brown. There appear to be the remains of an old boat in the muddy foreshore. How long have they been there?
