  1. Feadship launches 83.5 meter hybrid superyacht "Savannah"

    Inspired by the 2010 Feadship Future Concept Breathe, Savannah is a demonstration of thecost-effective and cleaner mode of propulsion that can be achieved within an entirelybespoke superyacht. Savannah has a dynamic hull shape with a very fine entry, uses oneefficient medium-speed Wärtsilä main engine instead of two higher-rev diesel motors, asingle central propeller shaft installation on the centreline and three gensets.Feadship has launched the 83.50-metre (273’11”) Savannah, 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 thirty per cent, 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.
  2. Redundancy is ensured by fitting a large contra-rotating and azimuthing sternthruster just aft of the main propeller. The design of the aft ship allows for a propeller that is forty per cent 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 sternthruster also ensures excellent maneuverability in marinas. Taken as a whole, the package offers major benefits in terms of fuel saving and consists of five modes: manoeuvring, diesel-electrical, range, high speed and boost. This guarantees a high level of reliability and a better engine load than any other superyacht afloat today.
  3. “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. “Feadship has leveraged on all the options available in the marine industry today to bring this hugely innovative system to completion. “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. Only Feadship engineering and the rich experience of this yard could have successfully concluded a project of such scope and vision,” McCumber continues.
  4. But there is much more to Savannah than her extraordinarily efficient propulsion system. 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. 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. Feadship developed a special spray nozzle technique to attain the all-metallic look which had to be achieved in one sweep to avoid any color discrepancy. The outside staircases are jet black and the steps covered in teak.
  5. 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-meter 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. Savannah also has unprecedented facilities for her 26 crew members 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. Another major innovation is the batteries, which were suggested by the owner. These provide extra speed at the top end, allow proper loading of the generators at any speed and facilitate super-quiet cruising at slow speeds without any engines turning. Li-ion batteries with no less than one million watts were installed.
