World’s Largest Battery-Electric Ship, China Zorrilla, Enters Service On River Plate For Buquebus

The world’s largest battery-electric vessel, China Zorilla, has entered commercial service after completing its maiden trip between Buenos Aires, Argentina, and Colonia, Uruguay, on the Rio de la Plata.

Previously known as Incat Hull 096, it was built by Australian shipbuilding company Incat Tasmania for ferry operator Buquebus.

It was launched in Buenos Aires on October 21, 2026, with the event attended by officials from Incat, Buquebus and maritime authorities from Uruguay and Argentina.

Named in honour of the late Uruguayan actress and cultural icon Concepción “China” Zorrilla, it links Colonia del Sacramento, Uruguay, with Buenos Aires, Argentina. Robert Clifford, chairman of Incat, said China Zorrilla is proof that high-capacity vessels can sail using battery-electric propulsion.

The largest battery-electric vessel is 130 m long and 32 m wide and can accommodate 2100 passengers and 225 vehicles. It has three decks and a 2,300 m2 duty-free retail complex.

The energy system exceeds 40 MWh, with more than 250 metric tons of batteries provided by Corvus Energy. The system propels 8 electric motors connected to waterjets, giving it a speed of 25 knots.

The vessel covers the 55-60 km route in 90 minutes, eliminating vibrations, toxic gases, and carbon emissions, while making the journey comfortable for passengers and harmless for the environment.

Incat officials said the vessel has revolutionized ferry standards by offering luxurious travel. Electricity generated from wind farms and hydropower goes to the Uruguayan grid, and from there to China Zorilla’s batteries, making the operation truly sustainable.

Incat Tasmania plans to use its technical expertise for expanding electric shipbuilding in Hobart. According to sources, it is building three 129-metre-long battery-electric and two hybrid catamarans for European and international operators.
