The 2017 i-Novo Eco prize went to the Solarwave Silent-75, a catamaran cruising yacht with hybrid propulsion. The Swiss manufacturer claims unlimited range for its globe-straddling cruiser, thanks to paired electric motors producing 135 kW of power each, with a 400 kW option. The roof over the main cabin, flybridge and aft cockpit is covered with solar panels. The system offers 20,000 Wp of generating power and features one or two 100 kW generators. The diesel engine fuel tanks hold up to 3000 liters.
The 75 has an overall length of 22.8 meters, a beam of nearly 10.7 meters and a draft of 1.2 meters. The starboard hull houses a tender garage and an aft hydraulic platform can handle a tender or jet-ski. Layout options offer three to six cabins plus a crew cabin. Cruising speed ranges from six to 15 knots and top speed from 10 to 20 knots, depending on powerplant options. The boat can carry between 1000 and 2000 liters of fresh water and has two 500-liter holding tanks.
