German eco-industrialist Guido Krass is offering to sell his 241-ft. Silver Zwei (above), the world's fastest long-range superyacht, for €59 million (about $85 million). Designed to the billionaire's specifications by Monaco's famed Espen Oeino, the Silver Zwei is about as an environmentally friendly as a yacht of its size and speed can be.
That means high fuel efficiency, which is quite handy when crossing the Atlantic at a cool 22 knots. The yacht's light, airy interior has accommodations for 20 guests in nine cabins including a large owner's suite with private lounge and veranda deck. Earth tones and clean white spaces with orange accents abound.
