Based on his research at
Macquarie Graduate School of Management, Bethune set out to prove that hydrocarbon fuels could be replaced by sustainable
bio-fuels. He had
Earthrace designed by
LOMOcean Design and built in order to break the world record for a
circumnavigation of the globe by a powerboat in hopes that it would call attention to the viability of
biodiesel as an alternative fuel. He mortgaged his New Zealand home and financed the building in the hopes of recouping the expenses from sponsorship. He declined a $4 million sponsorship from a company that would have required them to use regular diesel. His first attempt began in Barbados on 10 March 2007. He encountered significant delays due to issues with the propellers and other mechanical problems. On the night of 19 March, while around offshore from
Guatemala,
Earthrace collided with a local fishing boat. The crew was absolved of any responsibility after a 10-day investigation during which they were held in custody under armed guard in the military compound in
Puerto Quetzal. The delays prevented them from completing the circumnavigation in record time using their original start location.
The crew took
Earthrace to
San Diego where they made repairs. They then restarted their record attempt, leaving
San Diego on 7 April 2007. Once they rounded
Aceh in Indonesia and started crossing the Indian Ocean the vessel encountered significant bad weather in the first
monsoon of the season. The
monsoon remained with them all the way to
Salalah in Oman. The vessel passed through the
Suez Canal, then when getting close to Spain, crew discovered a structural failure around the depth
transducer. Bethune said the "failure was a result of the constant pounding in crossing the Indian Ocean". The crew made temporary repairs and headed out to cross the Atlantic, however the repairs failed and Earthrace limped back to port in
Málaga, Spain. Bethune decided to abandon the attempt. Bethune returned to
New Zealand to recover from what he said was "a brutal ordeal". After meeting with some of his original sponsors, he assembled a new team. The vessel was repaired and departed from
Sagunto, Spain, in another record attempt on 1 March 2008. The second record attempt also suffered a large number of setbacks. The auto-pilot system failed in the
Atlantic crossing. This was repaired in
Puerto Rico. There was a general strike in
Panama Canal causing 3 days in delays waiting to transit the
canal. In the leg between Hawaii and
Marshall Islands, there was a problem with the
common rail injection system, which was repaired in
Majuro. The crew then had their biggest setback in Palau, when
Earthrace hit a submerged log a few nautical miles offshore. The vessel limped back into
Palau with extensive damage. A list of problems included a bent
driveshaft,
propeller damage, smashed P-Bracket, smashed engine mounts, broken
gearbox,
rudder damage, and a 5-metre gouge down the
starboard side of the composite hull. Crew determined it would be almost impossible to repair the vessel quickly in
Palau. They made temporary repairs and ran on one engine to Singapore. On arrival, the initial assessment was repairs would take at least 2 weeks, which would make the record almost impossible to get. The marine salvage company Posh Semco offered to help with haul-out, and the vessel was pulled from the water. The crew worked around the clock for 3 days.
Earthrace was put back into the water with what Bethune described as "the ugliest composite repair" he'd ever seen. The crew continued on their voyage towards their finish line in Spain. Bethune later confessed the reason they missed the record on the first attempt was his leadership was poor. He said the real difference in the second successful attempt was he did a better job in making decisions and running the team. He also claimed his team had been outstanding in Singapore. They had achieved a small
miracle in getting
Earthrace repaired so quickly, in very challenging circumstances. ==Earthrace Promotional Tour==
