Emerald

The wreck known as the '�Emerald'� is probably the wreck of the Hibiscus, a wood-hulled twin-screw steamer which was built in 1864. She was commissioned into the US Navy at that time, was used during the Civil War, and was then decommissioned in 1866 and later renamed Francis Wright. Later, after being renamed back to Hibiscus, she sank just off the New Jersey coast after breaking a propeller shaft. Nothing has been found to actually name the vessel although the discovery of artifacts dating from 1872, as well as the presence of the US Navy emblem on some items, seems to indicate that the Emerald is the same ship as the Hibiscus. The size of the Emerald also corresponds to that of the Hibiscus, and today one can find twin engines (with some of one of the propeller shafts missing) onboard the wreck which seems point towards the Emerald and the Hibiscus being one and the same.
