Suddenly, as dusk fell ...

I looked out of the window, casually, and saw this wonderfully large cruise ship gliding down the quiet Firth, all its lights shining and lighting up the water. I have only ever done river cruising, but despite the un-traditional lines of modern cruise ships their departures always make me feel a romantic longing to be aboard, looking out at the land where people are going about their business unaware of the self-contained world drifting past them.

I had to choose between hanging out of the window to catch a photo before it went too far downriver or firing up the computer to find out what ship it was. The photo won - if anyone can tell me, I'd be happy.
