Delta introduces Onika with a new high efficiency hull design

Delta Marine has recently unveiled its latest project, a 40m superyacht with a new high-efficiency hull design. Built for repeat Delta owners, Onika embodies the simple elegance and warmth of a true Gentleman’s yacht. The Delta Design Group was entrusted with the entire design and engineering package, beginning with the challenge to design a hull for shallow draft cruising with the same seaworthiness and capabilities as a full-displacement design.

Jay Miner, chief naval architect at Delta Marine, stated, “The new Delta hull design combines the best in long range passage making capability and fuel efficiency along with moderate draft 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.”

Stepping inside, the major focus of detail on the main deck centres on the dramatic entry and central staircase. Cream coloured marble floors with diamond-shaped Blue Sodalite are contrasted with raised and fielded wall panels of Khaya mahogany. Intricately carved wood handrails and metal-adorned newel posts anchor the base of the stairs. This theme of ageless and casual elegance continues through to the formality of the dining and main salon, with coffered style beams and pocketed beveled glass doors. There are several pieces of the owner’s selected antique furniture that add an Edwardian period to the room. In addition, both the dining and main salon feature fine pieces of the owner’s collection of original impressionist art.

The lower deck features panelled walls of clear, straight-grained German Spessart oak, finished naturally to a light honey colour. Dressers and feature furniture pieces are bow and serpentine shaped, meticulously detailed in mahogany and chestnut burl with Anigreinlay. Ceilings are white painted beams with soft fabric panels. The heads are finished with heated marble floors with the stone extending up to a wainscot with nautically inspired wall coverings. Other fabrics display a dramatic colour panel of rich blue, red and green jewel tones and textures.

Entering the sky lounge is a display of the natural beauty of materials and craftsmanship of the yacht. Large windows and light colors brighten the space, highlighting the German oak, painted antique white wood bookcase and teak planked floors. This is a space for the guests to relax, entertain or play card games among the carefully detailed furniture pieces. A corner quarter round mahogany bar cabinet with pocketing doors is to one side and a bow front end table in striped Sapele and Anigre veneer to the other. The loose furniture is soft and casual, upholstered with brass nail heads with cotton Ikat and pattered fabrics. The mixing of traditional components and materials lends to a British West Indies relaxed ambiance.

Onika’s outdoor spaces and decks are characterised by the same elegance as the interior, as the decks flow gracefully from bow to stern. The sun deck is a complete outdoor living space, with forward facing settees, a dining table for eight with a bar and TV, as well as room for chaise lounges with an outdoor shower to cool down. A pair of tenders, 18’ & 12’, are stowed on the aft bridge deck, able to launch to either side. On the main deck, there is dining for six, teak chairs and a lounge in a comfortable residential setting.

Powered by twin Caterpillar C32 main engines, Onika has a 4,000 nautical mile range at 12 knots and a maximum speed of 16 knots. Quantum Zero Speed stabilizers ensure a nice gentle ride both at anchor and underway. Her Northern Lights generators are equipped with catalytic soot traps for reduced emissions. Also included is a hydraulically activated fold-down mast, custom built and designed by Delta.

The launch of ONIKA is expected to be spring 2014; for more information, visit Delta Marine.
