HSC Francisco is a high-speed catamaran built by Incat in Hobart, Tasmania. Powered by liquefied natural gas, she is currently the fastest passenger ship in service, reaching a speed of 58 knots (107 km/h; 67 mph). Propulsion is by two GE LM2500 gas turbines, coupled with two Wärtsilä water-jets.
HSC Francisco was built in 2013 and is sailing under the flag of Uruguay. Her carrying capacity is 500 t DWT and her current draught is reported to be 3 meters. Her length overall (LOA) is 99 meters and her width is 26.48 meters.
Liquefied gas is used to run GE Power’s pair of gas turbine engines, converted from a Boeing 747 engine and has a total capacity of 59,000 horsepower. Through a 7-speed sequential gearbox, the power from each turbine will be transmitted to a propeller to drive the water jet engine.
The catamaran is owned and operated by Argentine-Uruguayan ferry company Buquebus. Francisco plies the 146-nautical-mile (270 km; 168 mi) sea route between Buenos Aires and Montevideo.
