When I read this article, very curious to find out this ferry configuration hence this finding: "Francisco is capable of sailing at a speed of 51.8kt with a deadweight capacity of 450t." then the rest of findings.. Aussie can build fast ferries indeed.
Francisco (formerly Lopez Mena) is the first dual fuelled high-speed Ro-Ro ferry to operate with liquefied natural gas (LNG) as the primary fuel. The high-speed ferry was built by Incat for its operator Buquebus.
"The vessel will operate on the River Plate, between Buenos Aires, Argentina, and Montevideo, Uruguay."
Incat was awarded the construction contract for the catamaran in November 2010. The design works were carried out by Revolution Design. The vessel was constructed at Incat's Prince of Wales Bay shipyard in Hobart, Tasmania. The vessel was launched in November 2012, with sea trails commencing in March 2013. The energy-efficient vessel was named in June 2013.
The vessel carries the 1A1 HSLC R4 Car Ferry B Gas Fuelled E0 class notation. It will operate on the River Plate, between Buenos Aires, Argentina, and Montevideo, Uruguay.
