A self-sufficient, silent, and emissions-free luxury catamaran

A bit of Baltic snow wasn’t going to disrupt Sunreef Yachts’ timing... the Polish shipyard has just launched, in almost polar weather conditions, the first example of its new Eco range. Though this might be an 80-footer, it is equipped with very advanced ecological technology, with the aim of envisaging cruising that’s entirely self-sufficient in terms of energy, that’s non-polluting, and silent... all without forgoing the luxury common to every catamaran launched at the Polish yard.

Some will see this as a marketing technique along the lines of “We're giving ourselves a clear conscience” – but they’re probably wrong if the 80 Eco is indeed capable, as announced, of supplying up to 36 kWp thanks to its innovative solar panels (ultralight, they are integrated into the hulls, the mast, the superstructures and the bimini). The electric propulsion is provided by twin 180 kW motors. Under sail, the Sunreef 80 Eco produces energy from the rotation of its two propellers. This hydrogeneration system is capable of producing more than 15 kWh when sailing at over 7 knots.
