South American customer, Buquebús. The aluminum ferry will be the ? rst fully electric vessel in South America when delivered in 2025, operating between Argentina and Uruguay.

It will have a capacity for 2,100 passengers and crew and 225 cars and will feature a duty free shop of over 2,000 square meters (21,500 square feet).

The vessel will sail on the longest zero-emission journey, at the highest speed, and will be charged with the world’s high-
