MY ''Ady Gil'' (formerly ''Earthrace'') was a , wave-piercing trimaran, which was originally created as part of a project to break the world record for circumnavigating the globe in a powerboat. The vessel was powered by biodiesel fuel, but was also capable of running on regular diesel fuel. It used other eco-friendly materials, such as vegetable oil lubricants, hemp composites, and non-toxic anti-fouling, and had features such as bilge water filters.〔 The first attempt at the global circumnavigation record in 2007 was ill-fated. The boat several times encountered mechanical problems, and collided with a Guatemalan fishing boat, killing one of the other boat's crew. While the crew of the ''Earthrace'' was later absolved of any responsibility, the delay forced the restart of the record attempt, while more mechanical issues later aborted it. In 2008, the second journey proved successful—though again, numerous technical problems had to be overcome before the record was achieved, with the vessel finally making the return to Sagunto, Spain after just under 61 days on June 27, 2008. In late 2009, it was announced that the boat, now repainted black and named ''Ady Gil'', would be participating in anti-whaling operations under the lead of the Sea Shepherd Conservation Society. During operations in the Southern Ocean, the vessel and the Japanese whaling support vessel collided on January 6, 2010, resulting in loss of the ''Ady Gils bow and one injured crew member.〔 〕 Each side blamed the other for causing the collision, and government agencies are investigating the incident.〔 The crew of the ''Ady Gil'' were removed from the damaged vessel〔〔 and the salvage operation was abandoned, with the vessel sinking the next day.〔ABC News, January 8, 2010, (Ady Gil sinks after whaling skirmish )〕 == Design == The vessel was designed by LOMOcean Design (formerly Craig Loomes Design Group Ltd.) and built by Calibre Boats in Auckland, New Zealand.〔('Earthrace' – around the world in 60 days )〕 The wave-piercing trimaran design allowed for improved speed and stability. The boat was fully submersible, able to cut through waves and go underwater.〔 The hull was composed of a composite carbon fibre and kevlar with a non-toxic anti-fouling paint.〔 The vessel was powered by two 540 horsepower Cummins Mercruiser engines that ran on an animal fat and vegetable oil mix biodiesel.〔 It could be run on diesel, biodiesel or blends.〔In general, diesel engines will run on a wide variety of oils—Otto Diesel demonstrated the first one running on peanut oil at a World's Fair—and typically any engine that will run on biodiesel will also run on petroleum-based diesel. The main problem in using biodiesel is keeping it from congealing and clogging fuel tanks, lines, filters, etc., and this problem does not exist for petroleum diesel fuel, which stays liquid at all normal operating temperatures.〕 To cool and provide fresh air to the engines, intakes were located on two dramatic fins. The ''Ady Gils twin propellers were mounted under the main hull, while the rudders were mounted in the pontoons. This design provided good turning at speed, but limited maneuverability at speeds below 12 knots.〔 Despite its design as an "eco-boat", David MacKay calculates that it has significantly greater energy consumption per passenger-kilometre than a jet-ski or the ''QE2''. The $2.5 million cost was mostly funded by sponsors, and the only luxury item aboard was the $10,000 toilet. When asked, "Regrets about the cost of it all?" skipper Pete Bethune replied, "No...You know, I do have the coolest boat in the world." 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「MY Ady Gil」の詳細全文を読む スポンサード リンク
