The vessel, with a capacity of 160 passengers, had 129 people on board when it overturned after departure, Xinhua news agency reported. The Navy said 21 people were rescued.
Three rescue teams were dispatched to the site and the fire department joined the operation.
Last week, the route which the vessel operates was interrupted several times due to prolonged low tide.
It is the second shipwreck in Brazil in two days. A ship sank between Tuesday and Wednesday on Xingu river in northern Para state in the Amazon region, leaving 19 people dead.
