Savannah Feadship

Feadship Launches World’s First Hybrid Superyacht

(With extra pictures) Feadship has launched the 83.50-metre Savannah, the first superyacht to feature an eco-friendly blend of single diesel engine, three gensets, batteries, propeller, azimuthing thruster and a streamlined hull shape.

The new yacht offers fuel savings of up to thirty per cent. Further innovation comes in the form of a floating superstructure, an underwater lounge, and “open” aft deck areas.

Breathe Concept

Inspired by the 2010 Feadship Future Concept Breathe, Savannah features three modes of propulsion: diesel, diesel-electric and fully electric. Savannah has a dynamic hull shape with a fine entry, one medium-speed Wärtsilä main engine instead of two higher-rev diesel engines, a single central propeller shaft installation on the centreline and three gensets.

Large Azimuthing Stern Thruster

Redundancy is ensured by the large contra-rotating and azimuthing stern thruster aft of the main propeller. The aft ship design allows for a forty per cent larger propeller than normal. 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 better manoeuvrability.

Floating Superstructure

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.

Savannah’s aft owner- and main deck areas have been designed as single giant open inside/outside spaces, enclosed by weather tight sliding doors.

Full Metal Jacket

The exterior colour scheme is sea foam metallic green. The 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 colour discrepancy. The outside staircases are jet black and the steps covered in teak.

Underwater Lounge

One of the structural highlights is an “underwater lounge” at port side where guests can watch the fish outside or swim in the nine-metre 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 can further accommodate 26 crew members. The yacht will be made available on an exclusive basis for occasional chartering.
