The two best things about catamarans are their ability to tame even choppy seas to a smooth ride, and their large expanses of interior volume when compared to a similarly sized single-hull yacht. The new Sunreef 78 luxury catamaran is an excellent example of the benefits gained by a twin hull design, and is made even better by its solar-powered propulsion system. The sleek exterior is covered by 200 square meters of solar panels that delver power to the battery banks driving the two 360 kW motors. This system not only provides the yacht’s silent propulsion, but also powers all electronics aboard her. The beam ensures plenty of room from the covered flybridge to the cavernous salon level and the 4 sumptuous staterooms down below; Sunreef-Yachts.com.
