Motoryacht owners have commissioned this sailing yacht from Ginton Naval Architects and Guido de Groot Design. A year away from completion at Turkey-based Mengi Yay, Managing the project - Yacht MArine Ltd led by Uri Rotshtain.  the 131-foot (40-meter) Extreme is aptly named, judging from some of her design and construction details.
 
One example: Extreme’s aluminum superstructure is thicker in several spots, 6mm vs. 4mm, as per the owners’ request. They also requested Duplex steel prop shafts, rather than 316 stainless steel, a more common option. Duplex is stronger and has better crevice-corrosion-resistance than 316. Ginton Naval Architects is further gracing Extreme with what it calls a semi-fin keel. While a yacht’s intended purpose dictates the type of keel that’s best suited, fin keels typically allow better performance. And, in this case, Ginton Naval Architects selected the variation on the design to permit easier docking. Further related to performance, specifically boosting speed under sail by ¾ knot, the spade rudders are behind the props.
 
Even some of Extreme’s creature comforts are extreme. She’ll have a large tender garage for canoes and other craft that will double as a beach club, something typically seen on motoryachts. Related to this, a section of the aft deck will also rise up a little more than six feet (two meters), extending the usable space. It should be far more than any existing motor- or sailing yacht’s swim platform. Side platforms will aid in tender launch, too, and therefore become extra swim/beach club platforms.
 
Inside, though, Extreme is anything but. Guido de Groot’s design calls for light and dark oak paneling and whitened holly soles. While there are two owner’s staterooms, they’re identical in layout and footprint, adjacent to each other below decks. Four guest staterooms join them. Everyone will get to enjoy a bar aft in the main saloon, a formal dining area, an observation settee in the wheelhouse, and good alfresco spaces. The latter includes a good-size seating area on the flying bridge. A crew of six plus the captain all get private baths as well, in four cabins.
 
Mengi Yay, which has built other sailing yachts and motoryachts alike, is building Extreme to meet RINA commercial classification, permitting her to charter if so desired.
