Low tide at Pettycur Bay but the channel is deep enough for large tankers at all states of the tide. This one, a gas tanker, was on its way back out into the North Sea heading for Rotterdam (Europoort).
The foreground lead-in lines are the remains of old wartime defences to prevent light planes/gliders landing on the sands. I have previously blipped them here:

Looking towards Edinburgh.
The background hills from the left are:
Arthur's Seat, Salisbury Crags, Calton Hill.
The buildings are the dockside areas of Leith and Newhaven.
