Stewart & Stevenson Services, Inc., based in Harvey, La., has delivered a towboat, Espiritu Paraguayo, to Asuncion, Paraguay to Navegacion Paraguaya Americana S.A., a company affiliated with the South American barge line ventures of Allen Mott. This is the third towboat purchased by Mott from Stewart & Stevenson, and the fourth towboat powered by Electro-Motive Division of General Motors (EMD) engines by S&S for Mott and Mott's affiliates. Espiritu Paraguayo was completed using the hull of Senator Eastland, previously owned by Brent Towing Co., Inc., Greenville, Miss., which burned in 1989 on the Arkansas River. After the fire, the vessel was towed to Superior Boat Works, Inc., in Greenville, and the machinery and deckhouse was removed and the hull was painted and stored.
