 The brothers <unk> and Nelson <unk> received the contract to convert the blockade runner into an ironclad in early 1862 with the name of Atlanta , after the city in Georgia . This was largely financed by contributions from the women of Savannah . Fingal was cut down to her main deck and large wooden <unk> were built out from the sides of her hull to support her casemate . After the conversion , Atlanta was 204 feet ( 62 @.@ 2 m ) long overall and had a beam of 41 feet ( 12 m ) . Her depth of hold was now 17 feet ( 5 @.@ 2 m ) and she now had a draft of 15 feet 9 inches ( 4 @.@ 8 m ) . Atlanta now displaced 1 @,@ 006 long tons ( 1 @,@ <unk> t ) and her speed was estimated at 7 – 10 knots ( 13 – 19 km / h ; 8 @.@ 1 – 11 @.@ 5 mph ) .
