Supposedly it is still a current license type, suitable for, say, a guy from a chandlery trying to call out to an incoming vessel, i.e. from the docks to say "Hey, you're heading to the west pier, we're on the east pier" and then five minutes later "Hey, we're in the launch, drop your boarding ladder."
Once on land, once on sea, both situations covered by one portable license.
Same thing for a non-commercial user, i.e. "Hey, come back, you left me n the dock" from a guest crew who will later be taking a dink over to the next ride. One by land, one by sea, the use on land typically incidental but otherwise illegal.
This is very definitely NOT a coast station in any usual sense.
