Sauter Carbon Offset Design presents the 22 meter Emax Excalibur built by Ned Ship, a Carbon Neutral Solar Hybrid Fly-bridge Cruiser that features a Photo Voltaic Carbon Epoxy Exoskeleton that comes with a 25 year warranty.

The Emax Propulsion System employs the most advanced form of hybrid diesel power to date. the VW Marine 350TDI and the GM Allison dual mode Hybrid Transmission with Delco Remy motor/generators. The GM Allison Hybrid Transmission which was developed with 330million dollars of DOE Grants, powers 10’s of thousands of hybrid trucks and buses oporating in everyenvironment from Arctic toTropic locations around the world.

The Plug-in Emax Excalibur has a top speed of 30 knots and can harvest enough energy per year to Offset up to 3,000 nautical miles of Carbon Neutral Cruising at 18 knots.

Richard Sauter head of design commented “ The Emax Excalibur is the world’s first Carbon Neutral Yacht built from molds in order to produce a semi-custom series which represents the first step in the
maritime industry towards the production of Post Carbon Yachts.
