The light clearly lit up the bow of the vessel, where no light should have been, in the middle of the Atlantic.

We were crossing the Atlantic Ocean in a Tidewater boat, M/V tough Tide about 100 miles north of the equator.  I had the midnight to four watch.  
With every light turned off including radar, I was turned towords the after part of the boat to turn over the tape cossette in the machine.  All of a sudden the whole bow was lit up, as bright as day, I turned around to see the light and it emediatly took off to the north and headed to a cloud.  The light veered around the cloud and dissapeared.  
The object made absolutly no sound, and manouvered like nothing of this earth.  
I am a pilot and I was astounded by the quickness of the craft and the intensity of the light.  I can still picture this as if it happened yesterday.  I made log entries after the occurance and informed the captain.  He told me it was a bird, I told him I didn't know what it was, but I know it wasn't a bird
Witness indicates that date is approximate.  PD
