the Southern Wind and Nauta Design teams to this stylish new stern
The design brief from Southern Wind for the new 100X was very focused on the idea of efficiency in all aspects of the design. For the naval architecture that means creating a hull whose volume is aggressively low on viscous drag. Compared to some of our recent designs for Southern Wind the beam-to-draught ratio is lower and the gross amount of wetted surface needed to surround the volume is relatively less. The benefits of that process are lower sail area and less keel fin area and keel bulb volume required to achieve the desired sailing characteristics and performance. At Farr Yacht Design we work closely
with the structural designers and the suppliers of the rig (Hall Spars) and keel (APM or Lemer) to optimise the naval architecture during the various design stages leading up to the creation of the hull shape. We rely on in-house resources and programs to conduct hydro research and provide insights into hull shape development for projects like this. The SW100X is offered with different
propulsion systems, propellers and keels. Even just since March when the project was announced considerable refinement has occurred. The most significant was an increase in the LWL to 28.9m to accommodate the final configuration and positioning of the hybrid propulsion system, tender storage and seaside lounge. The style of the after sections has been pushed a bit harder in the direction shown in the renderings (straighter and lifted at the quarter beam) to optimise the transom immersion throughout the typical range of heel. The hull shape works beautifully with hybrid or standard propulsion and fixed or telescopic keels. For all versions the performance
targets include speed comfortably greater than the wind speed in light winds and enough stability to push the point of reefing/staysail usage above 17kts. These targets are achieved with an upwind sail area of 502sq m and a preliminary ballast weight (keel fin and bulb) of 21 tonnes (31 per cent) in a 4m draught fixed keel. The SW100X includesmany features that have come to be well known in all the

successful SouthernWind/Farr Yacht Design/Nauta Design collaborations. Exceptional handling, precise balance and easily achieved performance are all hallmarks of the SW96, SW105 and SW108. The SW100X continues the tradition and builds on it by including the same attributes in an exciting new way with exceptional efficiencies and economies.
Massimo Gino,
Nauta Design Starting from conceptual work on the original SW100 in 2004, followed by the SW102, SW96, SW105 and SW108, we developed and gathered a comprehensive range of solutions. Meanwhile, Southern Wind collected a detailed understanding of the needs and preferences of their owners, captains and crew. The SW100X is a culmination of this combined intelligence and demonstrates a synergy between the requirements of the end user and the best possible solutions available today. First seen on SW105 Taniwha, then
SW96 Nyumba, the GT style is the core of the deck design of the new SW100X. The reverse windshield enhances the distinctive, sporty style of the coachroof while the new cockpit arrangement gives more space for sunbathing and relaxing. The softly sloped coamings covered
with maple wood are inspired by the new SW108 Hybrid, but reinterpreted for the 100X. The steering pedestals and winches have been moved all the way outboard to optimise the view and line of sight from the helms, and to improve the angles of sheets and lines. As a result the sailing cockpit is dramatically wider, now comparable in size to that of a 40-metre yacht. Starting from this new “wing island” design and the consequent increase of the cockpit width came the idea to store the tender transversally. Southern Wind conceived a brilliant new aft platform solution that operates as the tender garage cover. The SW100X interiors reflect a design
that embodies our love for sailing. The interior material palette also reflects our commitment to natural materials and sustainable living within our environment.
Southern Wind fabricates the internal carbon structures (top) and the hull moulds (above) for its boats in house
quarters located aft for a crew of four. For short-range use the four-cabin general arrangement is ideal for owners hosting friends on board, or for two families sharing a charter, one forward and one aft of the saloon. For blue water cruising it provides VIP double and convertible twin/double cabins amidships for owners and guests to use on passage. The upper saloon offers good views out on both sides when seated and a panoramic 270-degree view forward, port and starboard when standing. Like most Southern Wind yachts, the snug lower saloon can be configured as a TV lounge, office or bar. The deck design by Nauta takes its cues
fromthe widely admired GT style decks of several recent SouthernWind yachts, with the coachroof and cockpit coamings subtly raised to increase shelter and security at sea. Themost striking feature, however, is the impressively large seaside lounge that folds out of the aft deck, with various configurations of sofas and sunbeds, and a total area of 20sqm– twice this size of the beach club area on any previous SouthernWind yacht. Beneath all of this is a transverse tender garage designed to fit aWilliams 435 jet RIB with an ingenious launch and retrieval solution.
The options The performance package includes a mainsheet traveller, running backstays and a square-top mainsail. Owners can opt for hydraulic furling or manual operation for the code sail and gennaker, and can
