Whisper-Yachts 50

The first electric catamaran from a range of powercats from 40 to 60 feet

The success of Silent Yachts is being emulated, and that's surely a good thing! Symphony Marine is entering the electric catamaran market, but with more modest sizes from 40 to 60 feet, whereas the Silent range extends from 55 to 100 feet.

Guy Marchal, the founder of the Whisper-Yachts brand, asked Berret-Racoupeau Yacht Design to draw this environmentally friendly catamaran with 320 square feet (30 m²) of solar panels (6 kWp), a 200-kWh battery pack and two 100-kW Torqeedo electric motors. The Whisper-Yachts 50 should be able to provide “clean” propulsion at 5/6 knots. It can of course sail faster - up to 18 knots - but at that speed, recharging the batteries is necessary through the generator and/or the shore power. The deck layout does not seem to inhibit the surface area of the solar panels - many areas remain well clear. Inside, the nacelle offers a decent 375 sq ft (35 m²), generously bordered by sliding windows. The manufacturer offers a three or four-cabin version.
