Police and rescue agency officials said by late today morning a further 33 bodies had been recovered from the sea off the Indonesian island of Batam.
There were 101 people on the speedboat carrying migrant workers and their families that capsized in stormy weather early Wednesday morning, and 39 of the passengers were rescued. Two of its three crew also survived and were later arrested. Nine people are still missing.
"This search is not easy," said Abdul Hamid, head of the local search and rescue agency. "Strong winds and currents were hampering our efforts and the sea was murky, making it difficult for rescuers to look below the surface."
The boat was about 7.5 kilometers from land when it sank. Speedboats and ferries are a common form of transport in Indonesia, a sprawling archipelago. Sinkings are common due to poorly enforced safety regulations.
One of the worst ferry sinkings in recent years occurred off Sulawesi island in 2009, killing more than 330 people.
