Built in East Germany in 1961, the Sierra Maestra came from the V.E.B. Warnow Werft at Warnemunde, and is obviously one of this shipbuilding yard's type IV class, for she is a double of the Frieden on stamps of East Germany. The type IV's are 10,000 tons deadweight, 516 ft. overall length, 65 ft. breadth moulded and 27 ft. loaded draft, with slight variations in individual ships. The hull is strengthened for navigation in ice. Four 8-cylinder, direct reversible oil engines, built at VEB Machinenbau Halberstadt, drive twin screws.The Sierra Maestra is an all-welded vessel for general cargo trade, having six holds and four hatches with MacGregor covers and 14 light derricks for cargo handling, as well as a 50-ton heavy lift derrick and two deck cranes. Accommodation is provided for 12 passengers with a separate dining room, smokeroom and bar. Her gross tonnage is 6,747, and net 3,884.SG1124
