THE 1682 SHIPWRECK OF THE BRITISH EAST INDIAMAN JOANNA
The Joanna sunk on June 8 1682 while on her way to Surat on the West coast of India. She got separated from her convoy and sank in rough seas on a reef off the Southern most tip of South Africa sending 24 people to their death. Eventually, 104 survivors reached the Dutch colony of Cape Town, from which a salvage party was soon dispatched. The Joanna's cargo consisted of 70 chests of silver coins, of which the salvage party reported having recovered only about 28,000 guilders' worth.
In November 1982 the wreck was relocated. Sealit, an amateur diving syndicate, the South African Cultural History Museum and the National Monument Council worked closely together on the excavation. The group of South Africans divers led by Gavin Clackworthy, brought up silver ingots and over 23,000 silver cobs, most of them Mexican 4 and 8 Reales of Charles II in generally low grade condition.
