Sure, cars like the Cayenne and even the Panamera are enormous in comparison to the 911. But there's still only so big Porsche can go. That is, on land at least. Not one to be told to stick to its core business, Porsche's design arm has teamed up with a Singapore shipyard to design a state-of-the-art catamaran megayacht.We first reported on the RFF135 by Porsche Design and Royal Falcon Fleet back when the idea was announced, but now that the project has started to materialize, the two companies have begun releasing details and images. Worlds apart from the speedboat which Porsche Design penned for Fearless , the RFF135 is a massive twin-hull design measuring 135 feet in length (hence the name) with a 41-foot beam. That's enough space to accommodate 10 guests and 10 crew members below decks in 472 square meters of area, with another 208 square meters of deck space up top.That's almost unfathomably large, and to propel the vessel up 35 knots (about 40 mph), the catamaran will be equipped with twin V16 turbodiesel engines from German manufacturer MTU, each producing a massive 4,600 horsepower. Don't ask about miles per gallon – this puppy will drink down 750 liters of diesel every hour, but at least you're bound to look damned good doing it, right? Details in the press release after the jump and renderings in the gallery below.

[Source: Porsche Design]Bietigheim-Bissingen/Singapore. The Porsche Design Group and Singapore-based megayacht builder Royal Falcon Fleet have reached the first milestone of the construction of the RFF135. The first joint project for the two companies, it is a luxurious anomaly on the water: a power catamaran with a length of more than 40 metres. The outer hull and the interior are in keeping with the functional, timeless and puristic hand of the Porsche Design Studio at Zell am See (Austria), which was responsible for the styling.The appearance of the RFF135 is particularly extraordinary, as it was conceived as a "spacecraft on the water," as was requested by the customer. In this form, the catamaran platform offers completely new possibilities for configuration in exterior and interior design. Unlike a great number of mega-yachts, the interior was styled in a highly modern way and captures the dynamic contours of the hull.Its typical Porsche design is unmistakable: Luxurious and functional, it dispenses with floridness and opulence of any kind. On the contrary, an unadorned design and authentic, premium and comfortable materials constitute the flair of the interior. The generous impact of its space goes beyond established standards for a 135-foot (41.2 metre) yacht.After the successful completion of the development phase, the construction of the hull for the first RFF135 began in September 2008. At the end of the year, the hull will be relocated to Sweden, where the technological installations and interior fit-out will be carried out. Royal Falcon Fleet has engaged the Kockums and the Incat Crowther firms for the construction design of the catamaran. Kockums, a Swedish subsidiary of Thyssen-Krupp, is known for leading-edge technology in the area of marine technology. The Australian-based shipbuilding engineers of the Incat Crowther firm have decades of experience in the construction of large power catamarans. The launch of this first Royal Falcon Fleet power catamaran designed by Porsche Design is planned for the fourthquarter of 2010."In 1987, we designed the 'Kineo' power yacht, an exclusive speedboat, of which there are only three examples worldwide and which drew attention for its characteristic dolphin form," says Dr. Jürgen Geßler, CEO of Porsche Design Group. "Our newest project once again demonstrates that our design, outstanding in many ways, is setting trends in numerous fields. With the first Royal Falcon Fleet yacht, we are building a bridge to the Porsche Design Sport textile collection that was developed specifically for the maritime area.""We have now reached an important milestone in mastering this path-breaking project," says M. A. Zaman, president and CEO of Royal Falcon Fleet. "Under the guidance of highly qualified experts from Australia , France, Sweden and the U.S., we are constructing the hull of the RFF135. On December 15, 2009, it is going from Asia to Sweden, where it will be completed. And at the end of 2010, the first Royal Falcon Fleet will be launched – the ultimate luxury experience at sea."In many respects, this project is an anomaly," says Roland Heiler, executive director of the Porsche Design Studio at Zell am See. "The sole requirement from Royal Falcon Fleet was to implement contours outside of the stereotypical boat aesthetic. This gave us considerable creative latitude and the result was a revolutionary design – a real challenge for the ship architects. This innovative yacht concept quickly drew them into its thrall, however, so that all the participants are now working painstakingly on the realisation of the design."Royal Falcon Fleet, a Singapore-based builder of luxury yachts, was founded by a Swedish investor. The goal of the firm is to develop mega-yachts that stand out for their innovative design, cutting-edge technology, and handcrafted European interiors.The Porsche Design Group, based in Bietigheim-Bissingen, is a majority-owned subsidiary of Porsche AG in Stuttgart.
