Deepest wavepiercing powerboat

The world’s most efficient wavepiercing powerboat is Earthrace, a 24-m (78-ft) long wavepiercing trimaran, which can submarine through waves at depths of 7 m (23 ft) – deeper than any other boat. Running entirely on biodiesel, and using hemp for the first time in any boat construction, Earthrace is also one of the most environmentally-friendly vessels in the world. Skippered by Pete Bethune (New Zealand), Earthrace set out to break the 75-day world record for circumnavigating the globe in a powerboat (and doing so using only renewable fuels) on 10 March 2007.
