Carbon Neutral Yacht

Introducing the world’s first “carbon neutral yacht,” the Emax Excalibur. The fly-bridge features a photo-voltaic exoskeleton that can harvest and return enough energy per year to offset up to 3,000 nautical miles! The Emax Propulsion System delivers advanced hybrid diesel power by combining the new VW Marine 350TDI v8 and GM Allison duel mode hybrid transmission- a revolutionary first step in the maritime industry.
