Actually, I believe that at the time the stuff that was considered the cat's whiskers was by a company called Decca. British I believe. And, at the time, unless there was reduced visibility, they saved costs by not operating the unit. This happened to be a very clear night so the radar would have been off. Also, at the time, the SOP was for a lookout on each wing plus the watch keeping mate in the bridge. People were cheaper then newfangled expensive technology Part of the duties of a good Captain (as well as Chief Mate, Chief Engineer and First Engineer). I had a good time but got tired of the box carriers (you're never more then 12-18 hours in port). Almost as bad as being on a tanker (one end of a pipe on one side and the same on the other side).
