On 22 March 1961 Arthur C. Clarke and Mike Wilson found an unknown wreck on the reef carrying sacks of silver coins struck at Surat for the Mughal emperor Aurangzeb, fused by three centuries of seawater into solid blocks of rupees. Clarke wrote The Treasure of the Great Reef about it. Anchorage: No anchorage. Kirinda is the launch point and the reef is a day objective in a flat-calm window. Hazards: A famously short season, the sea here is only workable in March and April, and the current runs hard the rest of the year. Más
