The 64 meter long tug Manhanuwara collided with the 102 meter long, 4900 dwt bulk freighter Thor Gitta near the grounded vessel Angel 1 off Mauritius.   Both vessels have been chartered for the salvage of the Angel 1 which sits on the reefs off Poudres-d’Or, Mauritius.   The collision resulted in only slight damage on the Thor Gitta.    Reports state the Thor Gitta proceeded back to the Angel 1 where it is transferring 32,000 tons of rice cargo.
