The 50-knot Sea Hawk...

Design

This Richard Sauter-designed 18m ‘carbon neutral’ flier is proposed for Dutch company Atlantic Motor Yachts.

JANUARY 2011

“The Atlantic Sea Hawk combines a plug-in SunPower solar array with an Allison hybrid system to produce one of the cleanest marine propulsion systems in the world,” says designer Richard Sauter of Sauter Carbon Offset Design. “Her state-of-the-art solar-hybrid technology addresses the issue of global warming pollution by achieving a 50-100 per cent reduction in fuel consumption and GHG emissions.”
Allison Transmission, a unit of General Motors, in partnership with the US Department of Energy, developed this hybrid system under the DOE's Advanced Heavy Hybrid Propulsion System (AH2PS) Program.
The energy from the solar array, combined with plug-in power sources, charge an Allison Nickel Metal Hydride storage system that runs hotel services and powers the express cruiser to her maximum speed of 50 knots. This same UPS allows her to navigate harbours and inland waterways with zero emissions
Plugged in the Atlantic Sea Hawk is capable of feeding 11MW-hour’s of electricity to the grid. That’s enough energy to offset up to 1,000 nautical miles of ‘carbon neutral’ cruising every year.
Rolls-Royce Kamewa water-jets are safer and high-speed waterjet-propelled yachts will use less fuel than boats of the same size with propellers.
