by Delta Marine Shipyard with Diane Johnson Design

Initially known as Project Invader, the impressive mega yacht Invictus is a major milestone in Delta Marine’s production history. From a technical point of view in particular, this build was a significant challenge for the Seattle-based US shipyard, which met the challenge very successfully.

The in-house Delta Design Group’s objective was to build a seaworthy, efficient transoceanic vessel, and to do this it created naval architecture featuring an ice-strengthened steel hull and a composite superstructure. However, most importantly, since it had to meet a tight delivery schedule, the Delta Design Group devised a construction plan with phases managed simultaneously in parallel. This meant that work on the hull and the superstructure could continue much more quickly than the traditional method with consecutive phases. As all the technical staff and necessary technological components are constantly available at the shipyard’s facilities, Delta coordinated and managed the entire production process fully in-house, with maximum efficiency and no unproductive interruptions. The finished hull, weighing 800 tonnes, was transported by water at the appropriate time from the metal facility to the main yard, where it was housed in the high bay assembly building to move on to the next phase: the adding of the superstructure. The latter, weighing nearly 140,000 pounds, was raised by three cranes with a load capacity of 550 tonnes and then positioned on top of the hull. Not only was the size of the pre-outfit superstructure module impressive, but the process with which it was designed and built was also remarkable. The Delta Design Group used its own advanced engineering and finite element analysis for technical evaluation to develop and prepare the components of the superstructure. The latter is a combination of composite, steel and aluminium, selected as appropriate depending on the most suitable material for each specific application and prioritised on the basis of the main build requirements: efficiency and strength, lightness and beauty. Thanks to this innovative approach to the design and build, the superstructure also has sculptural lines with dynamic curves, allowing the designers to make the best use of the interior spaces, achieve the maximum possible interior height, and include floor-to-ceiling windows with minimal stanchions. All of these features were expressly requested by the Owner of Invictus, who had the mega yacht he wanted delivered in record time. He and his family celebrated the debut of Invictus with some close friends in Seattle in July last year at a lively party at Delta’s shipyard before beginning the traditional maiden voyage. Impressive in size, mighty in stature and elegant from every vantage point, Invictus makes a commanding impression. With Delta Design Group’s exterior styling the yacht is a masterwork of design balance, cutting a supremely graceful silhouette with tailored lines and classic proportions. If you want to experience this magnificent mega yacht for yourself, Invictus is under operational management with Burgess and will also be offered for select charter by Burgess as central agents in the Caribbean, the Mediterranean and beyond. The yacht has an enhanced ability to accommodate extended worldwide cruising and allows the Owner and guests to safely and enjoyably cruise the world’s seas. For full enjoyment of the outdoors, the exterior decks flow gracefully from the fold-down beach cabana at the stern with its bar and day head, to the extra large sun deck complete with a hot tub spa pool, a bar and several areas for dining, lounging or gathering for cocktails. Details include custom stainless steel sconces, loose furniture with a gorgeous ebony and stainless steel table and a magnificent oval polished stainless steel handrail. Like the exterior spaces, the interiors of Invictus have also been designed to offer the maximum level of comfort and excellent spaces for socialising, which are permeated throughout with sophisticated refinement, expressed with stylistic elegance and inspired by exclusive grandeur. The stars of the picturesque fittings are the generous dimensions and the light in the spaces created on board the luxurious vessel. Thanks to the yacht’s broad beam and expansive interior volume with its careful planning of space, the interiors feature high ceilings and spacious rooms emphasised by low bulwarks and large floor-to-ceiling hull side windows that bring the outside in, providing a dramatic panoramic view of the outdoors. Maximising the opportunities to experience the beauty of the surrounding environment is a key consideration throughout the design of Invictus, culminating in the forward-facing master stateroom with its 180-degree view of the ocean.

The whole of the upper deck is a private Owner’s oasis that includes a salon and office plus an external deck. This arrangement allows for six large guest staterooms to be located forward on the main deck and provides incredible views of the outdoors for guests. Furthermore, the main deck features an impressive main salon with nearly floor-to-ceiling windows and high ceilings. Coupled with the low bulwarks, the result is a dramatic panoramic view of the outside. In the main salon, a grand piano sits unassumingly amongst a mixture of furniture perfect for small and large gatherings, and the main deck also features a cinema with raised stadium seating. On a separate deck, the dining room is framed by curved sliding glass doors with an expandable table that can seat more than 20 guests. In addition, each deck has a sizeable pantry for service. Additional highlights include an on-deck gym with sliding doors and magnificent views. Many of the spaces have been designed to be very flexible in use so that both large parties and intimate gatherings can be held; large spaces and opulent foyers are mixed with intimate settees and lounges. Family living was the keynote of the interior design brief, and as such, Invictus combines luxury and beauty with comfort and hospitality. Overall, the interiors are a harmonious mix of modern and antique, intimate but elegant, familiar yet completely original. However, every touch-point reflects the classical, clean, timeless vision and tastes of the Owners and their family, bringing to life a dream and a vision that can only be realised in truly custom yacht building. Diane Johnson of Diane Johnson Design, working with Johnson Wen Mulder Associates, was set the task of creating something new in yacht interior design, and succeeded. The result is a pure work of art that transcends description, incorporating both traditional and modern influences to create a cool sophistication that is still warm and welcoming. Elements of this transitional design can be found in the intricate detailing of the balustrade and the whimsical nod to the playfulness of the Rat Pack era in the sky lounge. The interior favours traditional classic yacht design with burr walnut and crotch mahogany veneers, raised panelling, beamed overheads, fluted columns and fabulous custom designed Lalique glassworks. Hallmarks throughout include different combinations of exotic woods, such as olive ash burr, Brazilian cherry, khaya and teak in traditional veneers, with intricate patterns and polished finishes. Gorgeous rare granites and marbles such as Black Onyx, Bardiglio Dark, Calacatta White, Absolute Black, Black Greek, Grigio Carnico, Carrara White, Botticino Fiorito, Kenya Blue and Green Labradorite have also been used.
