Via TugTalk we have report of investigation by Philip Simons:
"This is to try and sort out these ex US Army “ST” tugs as best as we can.
Confirmed by the Registry of US Army vessels (by the Office of Chief of Transportation), the following details:-
ST1982 Groton, ST 2115 Fort Moultrie, ST 1981 Ridgefield & ST2113 Charlestown
Confirmed by my own sightings when first moved to the R Itchen by 3/95
ST 1982 Groton became Elektra and went to Jersey as a MY (The current owner of the Whitby boat went to see it and its owner insists still a tug not a yacht)
The next three tugs were all bought by Gordon Read of Read Heavylift, Newquay.
ST2115 Fort Moultrie became Able One
ST 1981 Ridgefield became Able Two
ST 2113 Charlestown became Able Three
We know that Able Two was sold in 2003 and went to Ostende last reported to me 7/04.
We also know that Gordon Read made one ready to go to Florida, and according to Graham at Itchen Marine Towage left on trials and was never seen again though she has been reported in Florida for sale.
Now for the third tug, I asked through a friend who is purchasing a barge from Itchen Marine, to ask which tug went to Saxon Wharf for sand blasting in 6/03. They could not remember but told me to contact Marina Developments Ltd at Saxon Wharf and gave me the names of the sand blasters. I rang MDL the sandblasters have since left and they couldn’t remember the name. Now when I was there in 6/03 and asked the sand blasters the name of the vessel they were blasting, they said Able ONE. I then rang Whitby Harbour Master, who said no name is showing and none given. He gave me the phone number of the boatyard where she lies who told me there was no name on the boat. They gave me the phone number of the architect working on behalf of the owner, who said that they only know the boat as Able ONE. A little later the owner rang me to say that he knew no details, but he had bought the yacht from a colleague of Gordon Read and took it to Hartlepool and more recently to Whitby for conversion. He only knows her as Able ONE. (She has no engine so we can’t go back to the. US army with the engine serial number)
However I think it is more than likely that the one that went to Florida was Able THREE ex ST 2113 Charlestown
and that the boat now lying at Whitby is Able ONE ex ST 2115 Fort Moultrie."
