How to clean your windows

I'd wondered over the last couple of days how they would clean the windows which are up so high on the boat. 
Well, I got my answer It's quuite a clever contraption that rolls along on rails and provides the platform on which the crew member can stand and wash the windows.
Very ingenious.
Now if only therywere a ingenious with their food. There are probably schools with better lunch buffets than this ship had.


Ah well...
