Wider 150

by Wider, Fulvio De Simoni and Wider Engineering & Associates

Wider 150 is the name chosen for this project by Tilli Antonelli for a very clear reason: marking out the Wider 150 as the project that represents the beginning of a new chapter for Wider.
Genesi contains a huge amount of technological innovation and Italian excellence taken to its furthest extremes, from Fulvio De Simoni’s stylistic skills to the technical expertise developed and implemented by the shipyard and the companies with which it has worked to achieve a result that we have no hesitation in calling extraordinary. Wider 150 embodies state-of-the-art hi-tech development applied to marine propulsion in the yachting world, with cutting-edge technical solutions that give rise to many of the aspects we are about to discuss. We will start here, with the choice of propulsion system adopted by Wider for this 150’ which will undoubtedly influence the concept of propulsion on board large yachts in the future. The shipyard opted for four gensets capable of operating sequentially depending on the energy demands of the two aft PODs, which have electric motors supplying 531 kW each. The four generators, each supplying 350 kW, are located in a completely soundproof room in the bow, a choice that has made it possible to free up the aft areas normally used for the engine room, giving the designer more room for manoeuvre when it comes to developing brand new solutions for the usability and exploitation of these spaces. This choice also made it possible to move the potential sources of noise and vibration towards an area that is generally not much in use during navigation, resulting in complete comfort at all speeds. The option to navigate purely using electric propulsion should also be borne in mind, thanks to the 544 kWh battery packs with which the yacht can travel 30 miles at a top speed of 5 knots. The fuel consumption is also extraordinary, and with it the autonomy range of this 47 m yacht, which can travel 4,700 miles at the economy cruising speed of 10 knots or 2,000 miles at the top speed of 14 knots, based on tanks holding 45,000 litres of fuel. All of this is the result of careful hydrodynamic study to optimise the hull performance particularly as it interlinks with POD propulsion. In this respect, the special hull shape developed by Wider Engineering in association with SYDAC deserves a mention. Although it has a vertical bow, it uses a bulb which further optimises flow to reduce resistance. The special PODs produced by Dutch firm Veth Propulsion, used on all Wider yachts, also contribute to the result. For the electric motors, meanwhile, VISEDO was chosen – a Swedish company specialising in naval electric propulsion solutions. The battery packs were made by ESTechnologies and the whole system is managed by an automation and control platform produced by Emerson. As mentioned above, for this yacht Wider brought in first-rate international professionals, each specialising in a specific field but perfectly able to work together to achieve an uncompromising result. These include Italian group Team Italia, which developed the integrated bridge, the centrepiece of the sophisticated management and control system for all the on-board systems. Team Italia produced a fully custom design for this yacht, allowing all the systems and subsystems on board to be managed with an interface created in consultation with the crew to facilitate learning and therefore management. Also as mentioned above, the propulsion system has freed up space in the stern, so although there is a technical area there, it is obviously smaller and most importantly it does not have large engines creating noise and vibration. The special propulsion architecture has made room for the creativity and technical skill of the designer, Fulvio De Simoni, to develop entirely innovative solutions particularly for the usable spaces, both inside and out. One example is the large surface area of the owner’s suite at 75 m2, the largest ever recorded on a yacht in the 44-47 metre size range. It goes without saying that this space has a terrace over the sea, created by lowering part of the side wall which in just a few seconds automatically turns into an open-air space – but as we will see, it is not the only one. This element and the other design solutions clearly show a desire to ensure that the owner and guests enjoy contact with the sea at all times to a degree that is quite unusual for a vessel of this size. This is apparent in terms of both visual contact through the windows in the walls of every deck and the original solutions present in the stern. The stern truly embodies the best of all the usability concepts in play on the Wider 150’. In addition to providing space for a 32’ tender, again by Wider, this area transforms into a large beach area with a sizeable covered swimming pool, two side terraces and a platform partially protected by the stern hatch overhead. When all the component elements of this zone are open, i.e. both the side elements and the stern hatch, the result is a highly effective 90 m2 beach club a few centimetres from the sea. The pool created from the tender housing, and which therefore has the same dimensions, is located in a space that it is hard to see as a garage given the care taken with the fittings and the view of the sea on both sides and to aft. As mentioned above, a connection with the sea played a crucial role in the development of this project – the space we have just described undeniably best represents it, but the rest of the yacht never neglects it either. For example, the main salon has full-height windows from which the sea is always visible, even from a seated position on the sofas, while to aft, the large sliding glass doors connect this space with the main deck, creating a sort of large salon that is partly covered and partly open. The same principle is also in play in the upper deck salon, the ideal spot for open-air lunches, with a lounge area featuring sofas and coffee tables, a gaming table and entertainment systems. Here again, everything is connected thanks to the use of three large sliding glass doors. This space also has a very large surface area and most importantly the possibility of getting to the bow via the side gangways. The bow has another very important element, because the automatic movement of a mobile protective structure reveals a large open air lounge near a sunbathing area. Needless to say, this space enjoys privacy and a particularly good view, and is protected from above to make it usable even in the middle of the day in summer. However, the open air spaces are complemented by another critical element of this cutting-edge project, namely the large sun deck. While it does not break records for the yacht’s category the way other areas do, it is a large open air space with a perimeter structure in glass so that contact with the sea is not lost even here. The interiors were created by Ideaeitalia, to a design by Davide Bernardini and Alessio Battistini, who described their work on Wider 150 as follows: “The project was created with the intention of doing something completely new, which meant an unconventional layout designed to increase space and astonish those who experience it. Thanks to the innovative distribution of the technical areas, guests have a surprising amount of space for a yacht this size. All the spaces were designed to give the owner a feeling of immersive total comfort, where the perception of refined, discreet luxury is created through artisanship of the highest quality. The soft, elegant design seeks to strike a chord with guests, stunning them with innovative materials with a distinctive Italian flavour. The inlaid wood and metal castings are not intended to follow any kind of current trend, but rather to focus on the moment of their creation to obtain a timeless object. The fine Italian craftsmanship is apparent in many details, while the warm colours of the leathers, the mix of zebrano and wenge wood and the Travertino Romano convey a balance full of character. Two leading Italian design brands – Poltrona Frau for the interior accessories and Paola Lenti for the exteriors – further enhance a refined aesthetic.”

The staff on board this yacht can rely on comfort levels and entertainment areas that offer wellbeing even for very long periods, and they also have transit and service routes which, while carefully maintaining the privacy of the owner and guests, at the same time ensure that the crew have their due privacy too. To conclude, there is a further garage in the bow which holds a RIB tender and two jet skis. This is a revolutionary yacht, offering new interpretations of seagoing with brand new spaces and most importantly the possibility of sailing even in protected areas – and always in the utmost comfort. We would like to add a personal note to the description above, as we had the opportunity to see the yacht under construction at the yard’s Ancona facilities, and saw that the principle of quality is apparent from a great distance on this yacht. The unfinished hull was particularly striking, as thanks to a special cutting and welding system it appeared ready for painting even at that stage, or very nearly. When we asked Tilli Antonelli about it, this was his response:
We studied the process of cutting and joining the metal plates in great detail before proceeding, finding the solution in an innovative system which, as you can see, leaves perfectly smooth surfaces even after welding. This means that we have precise control of the weight of the entire structure, minimising the refinishing works needed afterwards. This technology involves a very carefully drawn up final design, and the same applies to all the interior structural elements and every component – the true greatness of this method is the attention paid to every phase of the project.
We are proud of the result because we have achieved what we had in mind since the beginning: creating a yacht that can offer our clients something they haven’t yet found anywhere else, and perhaps have not even imagined yet – and with Genesi, we have succeeded.”
