The license plate commemorates the HL Hunley submarine that sunk off the cost of Sullivan's Island in 1864 and was recovered in 1995. The fee for the plate is $100 every two years in addition to the regular motor vehicle registration fee. A portion of the special plate fee, $60, is distributed to the Save the Hunley Fund created by the Hunley Commission or another non-profit fund designated by the commission. The funds provide for the continued curation of the Hunley submarine. This plate is available to anyone interested in the restoration and preservation of the submarine.
