In issue 32 of Yacht Première, we published some initial preview information on Onika, a project then under construction. A high level of confidentiality had been maintained by the Delta Marine shipyard until that moment at the specific request of the Owners, who generously agreed to reveal some of the information only then. After a successful launch by the American shipyard and the formality of delivery to her Owners, we were at last able to prepare a full portrait of Onika and present the yacht to our readers in these pages. The Owners wanted to call their new motor yacht Onika, the same name as their previous vessel, which was also designed and built by Delta Marine and on which they enjoyed 20 years of cruising in complete comfort. They were so satisfied with their experience that they came back to the US shipyard to commission a new, substantially larger vessel – 7 metres / 23 feet longer – which also had some specific restrictions imposed by the client when it came to certain key measurements. Specifically, it was essential that the length and height of the motor yacht did not exceed the corresponding dimensions of the space available in the Owners’ boathouse and dock. As a result, in addition to the length overall, which is below 41 metres / 135 feet, a carefully engineered hinged mast can be hydraulically lowered to clear the Owners’ boathouse entrance. However, the exacting Owners also wanted a lot more, particularly a motor yacht with exceptional seakeeping capabilities, and specific technical parameters including a moderate draught and the right cruise speed and range for ocean crossings. In order to meet all the requirements and deliver a vessel with the greatest possible seaworthiness and stability to the Owners promptly, the Delta Design Group in-house team produced a completely new high-efficiency hull design and developed the entire naval architecture and engineering package for project 130043 (the yard’s internal code for the yacht from the design phase through to the construction phase). It is based on an innovative hull concept that combines all the best characteristics of a semi-displacement hull design and a full displacement hull design, achieved thanks to Delta Design Group’s experience and skill. Jay Miner, the yard’s Chief Naval Architect, had this to say about the outcome of the team’s commitment: “The new Delta hull design combines the best in long-range passage-making capability and fuel efficiency along with moderate draught to allow the Owner access to the shallower water destinations that otherwise might not be accessible. In profile, the bow has a long overhang, with enough flare to keep the decks dry and present an overall classic look. Below the waterline, the hull form has round bilges with a bulbous bow and long easy run to enhance comfort and reduce fuel consumption. Much attention was paid to the flow line patterns along the hull surface to ensure that all appendages were precisely aligned. The propeller tunnels are well blended into the hull, with a gentle transition resulting from studies conducted both by computational flow dynamics (CFD) as well as a traditional battery of physical model tests in a tow tank facility. The final result is a handsome design with the ability to cross oceans efficiently, in comfort and in style.” And it’s a stunning style, thanks to the skilful artwork and virtuoso creativity of the Delta Design Group in-house team, which devised both the exterior design and the interior design for Onika to create a genuinely unique vessel in perfect harmony with the wishes of the Owners, who wanted a yacht with modern technical content alongside a classic aesthetic intrinsically inspired by the simple elegance and homelike warmth of a true gentleman’s yacht. Onika therefore has monochrome livery in classic white, providing a luminous contrast for the equally classic, elegant shapes of the hull and the superstructure with their soft, flowing yet unexaggerated lines. The yacht has a traditional three-deck profile with wide gangways and generous covered areas. The external spaces offer plenty of choice for the Owners and guests, for example on the aft main deck which features an al fresco dining area and a lounge area. However, this level of choice is most apparent on the sun deck, a complete outdoor living space partially protected by a hard top, which has an observation area with forward-facing settees and an al fresco dining area with adjacent bar, as well as a sunbathing area with chaises longues, sun beds and an outdoor shower. Onika’s interiors are a magnificent expression of the welcoming warmth of a cosy home, evoking the enchanting atmosphere of an authentic gentleman’s yacht as per the Owners’ request. This atmosphere is interpreted through furnishings and decoration with a refined vintage flavour and a mix of traditional components and materials, sometimes inspired by an Edwardian style and other times by a relaxed British West Indies ambience. Onika’s fittings are exclusively designed to create a sophisticated, luxurious setting that is also serene and relaxing, based throughout on a careful selection of exquisite materials such as refined woods including mahogany, chestnut burl, anigre and teak, but primarily Spessart oak. This slow-growing variety, cultivated in managed forests in Bavaria in southern Germany, is highly prized for its fine, unusually clean grain, and it has a luminous appearance, especially with its pleasing natural finish in a light honey colour. Naturally, stonework and glasswork also abound in the fittings, aptly completing the spectacular interiors. This is notably the case in the entrance lobby and the central staircase, which are among the key elements and part of the key focus of the design, with a floor in cream-coloured marble inlaid with blue Sodalite diamond shapes in vivid contrast with the walls clad in raised, fielded panels of Khaya mahogany wood. These features are joined by other enchanting decorative details, such as the finely carved wooden handrail and metal adorned newel posts that anchor the base of the stairs. The predominant feel throughout is calm, ageless elegance, graceful yet also imposing, for example in the formal dining and salon spaces with their coffered-style beams and pocketed bevelled glass doors. Both of these reception spaces have several authentic Impressionist works of art selected from the Owners’ private collection, and the salon also has numerous pieces of antique furniture from the Edwardian period, again all from the Owners’ personal collection. The walls of the Owners’ suite and the private guest accommodation are clad in panels of clear, straight-grained German Spessart oak with a natural honey-coloured finish, while the dressers and furniture are bow and serpentine shaped, meticulously detailed in woods such as mahogany and chestnut burl with anigre inlay. All the ceilings have white painted beams with soft fabric panels, while the other fabrics are in a dramatic colour palette of rich blue, red and green tones and textures. The heads are finished with heated marble floors, with the stone extending up to a wainscot with nautically inspired wall coverings. However, it is primarily on the upper deck, particularly the more casual guest space of the sky lounge with its abundance of natural light, where Onika shows off the natural beauty of her materials and the sublime artisanal skill with which they were carefully chosen and worked to create every detail of the furniture. One example is the corner quarter-round mahogany bar cabinet with pocketing doors, which has striped sapele wood on one side and anigre veneer on the other. All the loose furniture is soft and casual, upholstered in cotton Ikat and patterned fabrics with brass nail heads. This effective mix of traditional components and natural materials lends the space a British West Indies flair – an antique flavour for a truly relaxed atmosphere. The whole ensemble is thrown into sharp relief by the natural light flooding in through the large windows, lighting up the space, setting off the colours and enhancing the tones of the walls clad in panels of German Spessart paint and the floor in teak slats, as well as the antiqued bookcase with its exquisite finish in painted antique white oak, providing a stunning showcase for the Owners’ rare antiques, small sculptures and book collection. Onika’s interiors have a sober, serene, timeless design created with stunning skill by the Delta Design Group team, incorporating both the furniture and decorative elements provided by the Owners as starting points and drawing inspiration from the classic yachts of the early 20th century, which are well known to and highly appreciated by the Owners, who have extensive sail and motor yachting experience. This strong personal experience on the part of the Owners has left its mark on the layout in particular, which features an unusual position for the master suite. Due to their desire to travel extensively on board, they opted for a convenient location low and amidships for the full-beam master stateroom. Many of the Owners’ other specific requirements presented an unusual challenge for the Delta Design Group team due to the abovementioned limitations on the yacht’s physical size. These include the lift from the lower deck to the bridge deck, and the pair of tenders – 12’ and 18’ in length – which are stowed on the aft bridge deck and can be launched from either side of the yacht. Although at the beginning, meeting all the requirements and achieving all the objectives looked to be a difficult task, almost a mission impossible for the shipyard’s staff, by the end of the project it is very clear that Onika has many of the characteristics typical of a much larger yacht. The American shipyard has pulled it off in style once again.
