The 91' Z-Drive tug is the latest in Martinac's line of combination towboat/ship-assist tugs. Unlimited maneuverability is achieved with a pair of Ulstein-Aquamaster 360° rotatable z-drives with PV-Duct nozzles and two 1600-horsepower Detroit Diesel engines. This formidable combination provides 105,000 pounds of forward bollard pull, with an equal amount when operating in reverse! Undaunted by ships or barges, the Martinac 91' Z-Drive Tug cruises at over 14 knots. |
