S1723 is based on Sulphur Enterprise on 14 December 2010. Built for Sulphur Carriers in 1994, she was sold on 28 August 2007 to ISC-Sulphur Holdings, a Capital One subsidiary, and leased back for ten years with an eight-year early-purchase option. Rosanoski found no earlier photographs to verify the funnel before the sale but thinks continued use likely because the original operator retained the ship on lease.
