"garth" was part of the original names of Rea Towing, IE Williwgarth, Dongarth, etc. Rea's were taken over by Cory and became Cory Towage, part of Ocean Fleets IE Blue Flu etc, they inturn sold out to Sviitzer which in turn was bought by Wijsmuller which in turn has been absorbed into the Maersk Group. they now have a monopoly of towing in UK ports and most of Europe as well it think.
