Dhaka's marine court has found a ferry owner and nine staff guilty of causing the Coco-4 ferry to capsize in Bangladesh in 2009.
The accident killed 81 people, with others said to be missing.
Judge Begum Shammi Hasina Parvin handed down four-year jail terms to workers and ordered the vessel's owner Rahman Shipyard to pay BDT 480,000 ($5,882) in compensation to the victims' families.
The Daily Star reported staff were also fined BDT 5,000 each.
The convicted men include the master and some other crew, plus clerks and an inspector.
They can now appeal the decision.
Coco-4 capsized near Nazirpur with around 2,000 passengers on board on 27 November, 2009.
Shipping minister Shajahan Khan told news agencies that officials had locked the ferry's exit gate as it approached the shore to find out whether anyone was travelling without a ticket. This triggered a stampede, causing the boat to tip, according to Wikipedia.
