Couach shipyard is delighted to announce the delivery of its second 50-metre Couach 5000 Fly yacht Belongers, following a series of intensive sea trials. Luxury motor yacht Belongers has achieved impressive results that clearly exceed market standards.
The innovative aspect of the luxury yacht Belongers is the level of comfort it obtains thanks to SilentCab® and VRS® (Vibration Reducton System) technology. Constantly leading the way in the development of new technologies for shipbuilding, Couach now redefines the standards of on-board comfort, offering a new sailing experience on one of the fastest yachts in its category.
INNOVATION –SILENTCABTM AND VRSTM SYSTEMS FOR UNPARALLELED NAVIGATION COMFORT
Couach hulls, already renowned for their unequalled sea keeping qualities, make each cruise a genuine experience where safety, power and fluidity prevail.
On board Belongers superyacht, the on-board comfort is the plus point that makes this yacht exceptional.
The outer layer of Belongers yacht, very similar to luxury yacht La Pellegrina (COUACH 5000 FLY #01), in all reality hides a major technical revolution. Faced with the challenge of a particularly demanding owner, COUACH has completely revisited the design of its 5000 FLY to meet the level of comfort required (in terms of noise and vibrations), both moored and at sea.
Developed by Couach’s R&D department following an exhaustive study carried out in conjunction with the VAN KAPELEN acoustics expertse agency, the exclusive suspension system SilentCabTM consists of disengaging the cabins from the source of vibrations. As if suspended, the cabins are isolated from the noises and vibrations caused particularly by the generators and engines.
VRSTM (Vibration Reduction System) skillfully complements SilentCabTM by providing an adequate and systematic response to vibrations generated by all the on-board systems. The complexity of vibration phenomena on the different navigation regimes and the interactions between different materials makes it necessary to establish a model and to analyse each parameter. It is the shipyard’s capacity to both take all these parameters and their interfaces into account and to implement a mix of preventive or corrective measures that makes it possible to achieve the performances obtained.
EXCEPTIONAL ACOUSTIC PERFORMANCES
And this has been successful, with noise and vibration test results far exceeding the ambitious objectives set by the owner. With just 42 db at 12 knots, noise levels in the owner’s cabin are well below those of the quietest luxury sedan car. When moored, levels drop to 35 db; comparable with the sound of wind rustling through the trees.
The chart below clearly illustrates comfort perception and puts noise levels into perspective: Equally, particular attention has been paid to vibrations, which are often a source of discomfort. Vibration tests display the same level of excellence with, for example, 1,78 mm/s measured in the upper deck saloon at 12 knots, against an average of 3 mm/s on most yachts on the market.
This technological performance is all the more significant as each modification made to the structure, hull or assembly methods, is characterized by an influence on the design, the associated systems, the boat’s weight and trim, while always retaining the same performances in terms of resistance, speed and power consumption.
ONE OF THE FASTEST IN ITS CATEGORY
Its top speed of 28,3 knots, measured on heavy seas, makes super yacht Belongers one of the fastest boats in its category. This, associated with its legendary hull, makes it possible to navigate in delicate weather conditions with the required reserves of power. This second COUACH 5000 FLY unit also offers efficient energy consumption and transatlantic autonomy at cruise speed.
Beyond simply validating the technical excellence of one of Europe’s oldest shipyards, these results also underline the merits of choosing to work with composite materials, including on super yachts of this size.
The overall construction of Belongers yacht has benefited from the scrupulous follow-up provided by Wintherbotham surveyors.
Among other things, superyacht Belongers illustrates Couach shipyard’s legitimacy in the realm of super yachts, having proved its capacity to execute a superb finish that meets the requirements of a justly demanding clientele. The owner and his surveyors have expressed their satisfaction in terms of constructi on quality and the impeccable finish for a vessel delivered on time.
This quality can be seen in the perfection of the interior fixtures, the result of the shipyard’s crafsmen’s know-how and a fruitful collaboration with METRICA® Interior. In pure COUACH shipyard tradition, the owner played an active role decorating and customizing the fixtures of his yacht in its entrety, creating his dream yacht, drawing on his fve years’ charter experience on the most prestigious super yachts.
RARE AND UNIQUE
Concerning the delivery of Belongers yacht, Christophe Kloeckner, President of Couach shipyard states: “Thanks to the innovations developed on this new 50 metre unit, COUACH reasserts the identity of the brand: intelligent shipbuilding and technological superiority, reflected in navigation comfort. Beyond these words, we highly appreciate the admiration and extreme satsfaction expressed by the owner’s experience sailing his COUACH. Couach’s R&D department is currently working on new technological innovations that contribute towards improving comfort, in order to maintain and strengthen this leadership”.
