    Re: Harbor Markers

    My thanks to Brad and David and all who contributed to this query! The full address of the article is: [deleted].

    I am surprised that ‘harbour /harbor markers’ (re chronometer rating) are so elusive or possibly dreamed up by the author! I can understand that  if they ever did exist they may have been short lived phenomena, rendered obsolete by wireless, lat/lon  listings etc.
