Bob,
The current
RESOLUTE, IMO 7367419, built in 1975, was acquired by McAllister in 2006 through the purchase of Providence Steamboat Company. She retained her previous name.
The former
RESOLUTE, IMO 6517550, built in 1950, was acquired by McAllister through the purchase of Barker Whiteley Towing Company, when she was renamed from RESOLUTE to DAVID MCALLISTER. However, for some reason, her name was returned to the original at some point. She would later be sold, I'm not sure of the year, to Patriot Marine, under whom she is still serving under the name OCEAN KING.
Regards,
Kyle
