As we emerged from the fog we could see the ships coming into the Strait just where our AIS system said they would be. This system allows us to 'see' commercial vessels in the fog. It was nice to see them visually and verify that the system works well.

Our system had been tracking the ship behind me in this photograph while we were in that fog bank (which can be seen beyond the ship). We crossed in front of him knowining his position, course and speed.
