UK design studio, Sauter Designs has devised a Mercedes Benz Blue-Hybrid Tender that demonstrates to the boating community how it can reduce 'Global Warming Pollution' by 280 million metric tons per year.

The Carbon Fibre Guardian S Class is a is 45 knot Solar Hybrid Vessel powered by an EPA car regulated Mercedes Benz Bluetec engine coupled to a Carbon-Grossbauteile electric motor. When combined with other currently available technology her Fuel Consumption and GHG Emissions are 50 to 100% lower than any speed boat ever built.

The Guardian’s Lithium ion UPS provides a Zero Carbon cruising range of up to 50 nautical miles while her plug-in SunPower array generates enough free energy to motor Carbon Neutral for up to 1,000 nautical miles a year.

Richard Sauter head of design comments: 'Taking advantage of existing advances in Green Technology, the Guardian S Class leads the way in attacking one of the major causes of global warming and in doing so lays the foundation for the only marketing force likely to revitalize the boating industry in the face of ever increasing fuel prices.'

While many look to revitalizing inland waterways, doing so without regulating the inevitable increase in pollution that will come as a result, will not benefit the related communities. By employing catalytic dry exhaust systems, Solar Hybrid power boats like the Guardian S Class are actively protecting rather then contaminating marine bio-systems.

The EPA estimates that registered recreational boats in the USA alone produce a staggering 375 million metric tons of Co2 per year. Carbon Neutral power boats that follow the Guardian’s example, can reduce that figure, by on average 75%, thereby reducing 'global warming pollution' by 280 million metric tons per year.
