It was pretty wild being underway on the west coast of the US and seeing a huge smear appear on the radar as a container ship swept by. If we were going north and they were going south the relative speed was really something. And the CPA (closest point of approach) would be a couple of miles, so you couldn't hear them, but wow, they were impressive.
