SAVANNAH — Coming off a year of record-smashing growth, Georgia's top ports executive said Thursday he's convinced the Port of Savannah can someday overtake New York as the busiest seaport for containerized cargo on the East Coast. Curtis Foltz, executive director of the Georgia Ports Authority, dropped the ambitious goal on a crowd of 1,300 Savannah business and civic leaders attending his annual speech giving a progress report on the state's ports. The Savannah port moved a record 3.1 million container units in the fiscal year that ended June 30.
