Her Story
The tugboat Lead Horse was built in 1969 by Burton Shipbuilding of Gulfport, TX, for the Caspary Wendell Inc. of Houston. She was sold in 1971 to Santa Fe Pomeroy Marine Service Co. of Houston, retaining her name. She was sold again in 1973 to Gulf Mississippi Marine, and renamed Gulf Challenger.
Gulf Challenger was purchased by Hannah Marine Corp. of Lemont, IL, in 1979, and brought to the Great Lakes region. She was renamed Challenger, and employed pushing tank barges for the Hannah Fleet. Hannah renamed her to Mark Hannah in 1993, and retrofitted the tug with a Bludworth style ATB coupler system and paired her with the tank barge Hannah 6301.
In 2009, Mark Hannah and Hannah 6301 were sold to Occidental (Oxy) Chemical Corp. of Houston, TX, renaming the vessels Spartan and Spartan II, respectively. Oxy contracted Andrie Inc. of Muskegon, MI, to manage the pair. Spartan and Spartan II continue to be active, transporting Calcium Chloride (CaCl2) from the Oxy Calcium Chloride plant in Ludington, MI, to ports across the Great Lakes.
