Probe into Robben Island ferry sinking

Passenger ferry began to sink on way back to Cape Town.
An investigation has been launched to determine why a passenger ferry returning from Robben Island to Cape Town started taking water and began sinking on the afternoon of 15 September.
The ferry's 64 passengers and four crew were evacuated by rescue services when the nose of the boat began sinking about 3 km from the Cape Town waterfront.
The South African Maritime Safety Authority is investigating the cause of the incident, which Robben Island museum management described as a "technical problem."
It was the first time that the ferry had taken to the seas again following lengthy maintenance work.
Thousands of tourists each year make the journey from Cape Town to Robben Island, a World Heritage site and home to a former prison where Nelson Mandela was incarcerated during the apartheid era.
