Back in the '80s, early in our cruising career and before we had GPS with anchor alarms, I would get up a couple of times a night during a night to take bearings on nearby landmarks to see if we were dragging anchor. So one night my wife got up at about 2am for a head-call, so after laying there for a few seconds gathering my wits I decided to go topsides and check my landmarks with the compass. Of course my wife didn't know this since she was in the head.

About the time she came out of the head I started to go below and appeared in the gangway with the full moon behind me.

She shrieked and shrieked uncontrollably - yelling my name and saying there was a strange man aboard. Of course I spun around and looked behind me ready to pounce, not thinking that the strange man was actually me!

After things calmed down we laughed and laughed about it. Still do.
