Earthrace circumnavigating on biodiesel

Posted By on March 5, 2007

EarthraceEarthrace, a unique 78 foot biodiesel powered wave-piercing trimaran, is at the starting line in Port Charles, Barbados. The sponsored project is looking to break the world record for circumnavigating the globe in a powerboat, and intend to do it on renewable fuel.


The team is skippered by 41 year old New Zealander Pete Bethune, who intends to showcase a myriad of environmentally friendly technologies; the engines are two 540 hp Cummins Mercruiser diesels, the use of non-toxic antifouling and a fuel efficient hull design. The trimarans hull “pierces waves instead of riding on top of them. Piercing the waves gives a smoother ride, and allows the boat to run at high speeds even in rough seas.” Their goal is to top the world powerboat circumnavigation record of 74 days, 20 hours, 58 minutes which was set in 1998.

The world record attempt will begin on March 10, 2007 although I’ve heard the 6th in a email from Donna Lange today. (which is why I’m posting this early) The Turbo.com channel of Discovery.com is covering this like nobody else, so that’s probably the best place to get up to speed and stay up to date. Oh … and if you think everything is going like clockwork, just read some of the Earthrace team comments.
