Its pointless to print and distribute something which is of dubious accuracy and certainly out of date when its easy to use a service like http://www.marinetraffic.com/ais/ which provides live updates to a complete world-wide view of all ship traffic located by GPS.
Its also possible to follow live updated, GPS located, world-wide air traffic on a map by using http://www.flightradar24.com/40.73,-74.08/10
The clients of old are not even trying to hang onto the old techniques.
