Big Mama Gets a Make-Over
When Zito Companies towed 32-year old Big Mama into their subsidiary, Inter-Coastal Marine Repairs, at Jefferson, La., from her lay-up berth in Pascagoula, Miss., she was a tired and worn-out boat. But under the rust and grim, was a fine ship waiting to be found. The propulsion system had been four engines arranged as a two tandems turning into two gear boxes. These were replaced with a pair of Cummins KTA38 MO engines rated for continuous duty at 850 hp at 1,800 rpm and turning into Twin Disc 540 gears with a 7:1 ratio and 74 x 68 in. four-blade props. The 73 x 26-ft. towboat, which is equipped with flanking and steering rudders, will be employed in fleeting operations by Zito themselves, rather than chartered as they have done with their other 12 boats.
