Feadship is hailing the recently launched 83.5-metre (273’11”) Savannah as the first superyacht to feature an eco-friendly blend of single diesel engine, three gensets, batteries, propeller, azimuting thruster and a streamlined hull shape.

Offering fuel economies of 30 percent, the pioneering electro-mechanical propulsion platform marries Feadship’s past experience and forward-thinking approach within a pure custom creation. Further innovation comes in the form of a floating superstructure, an underwater lounge, the open aft deck areas, and much more besides.

Inspired by the 2010 Feadship Future Concept Breathe, Savannah is a demonstration of the cost-effective and cleaner mode of propulsion that can be achieved within an entirely bespoke superyacht.

Savannah has a dynamic hull shape with a very fine entry, uses one efficient medium-speed Wärtsilä main engine instead of two higher-rev diesel motors, a single central propeller shaft installation on the centreline and three gensets.

The design of the aft ship allows for a propeller that is 40 percent larger than the norm. Combined with the power supplied by the thruster, the load on the propeller is only half that of a conventional twin screw yacht. This again results in a higher efficiency and fewer vibrations. In addition, the large stern thruster also ensures excellent manoeuvrability in marinas.

“It is not the individual technologies used on Savannah that are new in the yachting world – it is the way they have been combined,” comments the owner’s project manager, Ted McCumber. “The possibility to choose between diesel, diesel-electric or fully electric is truly exceptional. Moreover, Savannah is the first yacht in the world to be running with an azipull and a variable pitch propeller.”

The exterior profile created in partnership between CG Design and Feadship’s designers includes a ‘floating superstructure’. The glass and composite panels appear to float thanks to complex visual trickery involving polished stainless steel strips, aluminium supports and teak. The stainless steel doors form part of the yacht’s continuous line and also appear to be floating as part of an immensely complicated design feature.

Another unique aspect of the exterior of Savannah is the way the aft owner and main deck areas have been designed as single giant open inside/outside spaces, enclosed by weather-tight sliding doors. With the sides of the main lounge open, the entire space from the swimming pool to the saloon serves as a comprehensive al fresco experience zone.

“The owner of Savannah loves to be at one with the water,” explains McCumber. “This phenomenal design allows him to run from the main saloon and dive straight into the sea.”

The exterior colour scheme is Sea Foam metallic green – Savannah is the first superyacht to be entirely metallic painted (including the ceilings and fixed deck furniture) with the exception of the mast domes.

As the second superyacht venture from the boards of CG Design, the vessel comprises an unrivalled amount of detailing, finishes and materials throughout. For instance, there are lighting fixtures on the boat with up to 10 different colours, lens types and positions.

One of the many structural highlights is an underwater lounge at port side where guests can watch the fish outside or turn around and observe the fun and games in the nine-metre swimming pool. The room, which also converts into a cinema, is another first for a superyacht and features especially thick glass due to its position in the hull.

In addition to the owner’s stateroom, there are four large guest suites and one VIP stateroom with a balcony.

Savannah also has unprecedented facilities for her 26 crew and an exceptionally high-end tender bay finished in teak with a hatch that doubles as a mooring platform. After docking, guests can walk inside the garage and take the stairs straight up to the main deck.

Savannah is a yacht full of premieres,” emphasises Feadship director Henk de Vries. “As the first ever hybrid superyacht, she offers incredible flexibility in operations and loading of the power plant. The result is fuel savings of some 30 percent compared to the best boats that we have launched to date.

“More than 1,000 people have been involved with the creation of Savannah since the contract was signed at the end of 2011. And the tremendous final result once again shows how Feadship is never afraid to venture into uncharted waters.”
