The boat, carrying 55 people, was on its way to Rajamahendravaram from Kondamodalu when the incident took place.
But boat accidents are also common in India for other reasons mainly overcrowding, poor maintenance and lax safety.
The passengers had a narrow escape as the driver wheeled the boat to the shore and they jumped off before the entire boat was completely destroyed. On Wednesday, teams of Indian Navy and National Disaster Response Force (NDRF) brought a JCB from the nearby Polavaram project site but could not pull out the wreckage of the boat from the river. Many people are feared drowned in the boat tragedy.
Giving an update about rescue operation, the officer said, "We have been able to trace the location of the boat".
Prime Minister Modi condoled loss of lives due to collapse of under-construction flyover in Varanasi. He also extended his condolences to the families of the victims for those still missing. "I pray for the safety of those missing", he tweeted. It is believed to have capsized due to gusty winds.
Chief Minister N Chandrababu Naidu directed the officials to launch rescue operations on war footing. It is pitiable condition that four persons got killed from one family and it is painful to see the kids crying for their parents. Jagan Mohan Reddy has instructed party cadre to help in the rescue works.
Naidu blamed the private boat operator for the tragedy, saying the ferry was packed with men, cement bags and motorbikes.
