New Catamaran “Unicat” in Argentina

In September 2018, a 17 x 5m catamaran completed its ? nal tests in the Tigre Delta of the Tigre on the Parana River near Buenos Aires,

Argentina prior to its delivery to her Chilean owners. The cat was de- signed by Eng. Emilio Noel and built by Astilleros Unidelta SA. which has a well-established reputation in a wide range of steel and aluminum workboats. The yard has a plant located in Buenos Aires with 10,000 cu. m. of open and 4,000 cu. m. of covered work space. The shipyard also has an engineering of? ce located in the City of Buenos Aires.

The new catamaran has a capacity for 69 passengers and a three- member crew. The power for propulsion is provided by two Cummins

QSB 6.7 engines, each delivering 350 HP (261 kW) at 2800 rpm. The two mains are coupled to two heavy-duty Konrad Sterndrives 680 B series. This arrangement allows the boat reach a speed of 22 knots with a range of 600 nautical miles. The auxiliary power for the vessel ser- vices is provided by a Cummins Onan MDKBJ generator of 6 KVA.

Tankage onboard includes fuel tanks with capacity for 3000 liters as well as fresh water tanks with 300-liter capacity. The new catamaran, named Worsley, joins the tourism catamaran ? eet owned by the Chilean company Hipsur SA, whose headquarters are in Natale port, Chile. The boat is built according to Lloyd’s Register Class & Prefectura Naval

Argentina standards.
