The 197 meter long, 34,942 dwt freighter Angel 1 sank off Pointe-d’Esny, Mauritius after three months being aground on a coral reef.   Salvagers had made repairs and pulled the freighter free of the reef.  However, they found the hull had suffered many cracks.  These cracks enlarged as the vessel making repairs impossible.   Pumps barely kept the vessel afloat with it pumping out some 6,800 cubic meters per hour.   It was decided to tow the Angel 1 as far as possible from the coast and allow the vessel to sink.   When the vessel was some 36 miles off the coast, the crew was evacuated and the pumps were stopped.   The vessel quickly filled with water and sank.   The Angel 1 now rests under 4400 meters of water.   Reports state the Angel 1 still had some remaining cargo of rice on board.
