At the recent Monaco Yacht Show, a leading British yacht builder Sunseeker has revealed new Sunseeker 133 model. It will operate on a hybrid propulsion system developed jointly with Germany-based engines manufacturer MTU. Yacht Harbour discussed the future of hybrid propulsion engines with Darren Barnett, Marine Manager with MTU UK.Sunseeker 133Where does MTU decision to focus on hybrid systems for yachts come from?MTU has been an engine supplier for many years. The company is around 110 years old. Over that time, we have specialised in manufacturing and supplying light-weight and high-speed diesel engines.Now the time has come, when we have to be more than just an engine supplier, since the power requirements on-board yachts are getting greater. Owners of yachts want to operate them in a different way. They do not want to travel fast - they want to travel comfortably, economically and efficiently.Therefore, the best solution to that is to offer the system that can power the vessel in different ways. Thus, it would provide both propulsion and supply of all the consumes on-board, such as air conditioning, stabilisers and other hotel loads.Is that right, that speed is not the major concern anymore?Yes, that is what we say. So it is not all about having the largest, most powerful engines. It is about being able to offer better experience on-board, whilst the customers spend their leisure time there.Sunseeker CEO Andrea Frabetti and Darren BarnettWhat makes hybrid propulsion different from other engine systems?Diesel engines will remain the core of propulsion systems for boats in the future. Nonetheless, what we are doing is offering systems that can power a vessel using batteries, for example. We also deploy generators to provide power for not only propulsion, but also for conventional power needs on-board.Actually, the way all of that is linked together is a clever part, because the hybrid system itself is greater than the sum of all the components. You cannot just select components and install them into the yacht. Apparently, they need to be integrated together, so that they operate seamlessly. We believe, that there is a great future in yachting for hybrid systems.Our approach is that we will deliver the whole scope of supply. It means, not just the engine, not just a part of it but the whole system. Thus, we are also taking full responsibility for it. Customers want to have the knowledge that the complete system will be taken care of, because with complicated systems such as this one it can get difficult.Currently, we are developing a hybrid system jointly with Sunseeker for the Sunseeker 133 yacht. And we are looking into a modular and serialised system, since we want to have a portfolio of components to select from, such as different diesel engines and several types of batteries and generators. Sunseeker 133Do you think the hybrid propulsion system you are working on could be installed on other yacht models?The ideas is, with Sunseeker we have the first or pilot installation. Therefore, at the moment we are working on the scope of supply for the Sunseeker 133. In the future, the basis we have developed with Sunseeker will be available for other yacht builders with different diesel engines, different batteries and different generators. It will be possible to customise the system for any particular yacht.But is the system ready for installation yet?We are still in the development phase, but we are close to finalizing the total scope of supply. Hopefully, Sunseeker soon will be able to begin construction of the 133 yacht with the hybrid system.Then in the future, what do you think could be the largest size of a yacht to operate on hybrid propulsion?The serialized system we are developing with Sunseeker is aimed more at the production yacht market. Naturally, much larger yachts have much more specific requirements. However, we have done it in the past and that is what we will continue to do in the future.Operating as a custom service, we would develop a system to meet the customer’s requirements. That could be any size of yachts, up to the very largest ones. For instance, Sailing Yacht A operates on a kind of hybrid system, where MTU have supplied gensets.Many builders now opt for more eco-friendly engines in general. Have you noticed raising environmental awareness among yachting clients?Yes, definitely. Owners of yachts have realised that they probably could do something to more environmentally friendly. All the large yachts are the big consumers of power. What they could do, is raising awareness of where they can be more efficient. And it is obvious, that vessels running on diesels create emissions.Alternatively, with a hybrid system, all those large vessels could operate in harbours using batteries. It is a great benefit, that it is emission-free and completely clean. The only problem with hybrid is that for the moment people do not understand what hybrid is. It is a long process, and we are trying to educate people, what the capabilities of that system are.What is more, when a yacht is at anchor in a small bay and the owner of the yacht wants to swim around with family, they would not want a generator running with exhaust emissions coming on to the water. The environment would much nicer if there are no diesel engines running. We see it is a great benefit.

Brokerage company SuperYachtsMonaco has presented a new futuristic superyacht concept Project L by French designer Thierry Gaugain. Known for collaborations with Philippe Starck on several yachts including M/Y A, S/Y A and Venus, he is now presenting his solo 120-metre project. Project L will accommodate an indoor and outdoor cinema, nemo room, beach club, spa, gym, live performance area, dive centre, polar gear room, pools and a tender drive-in garage. Designer Thierry Gaugain, working on this project, did not limit himself to established frameworks. For example, it seems that the ship is generally devoid of windows, but this is not so. The area of ​​glazing is actually large, just glass with one-sided visibility.Project L has a focus on sustainable yachting and will be powered by a diesel-electric hybrid propulsion system with azimuthing thrusters fore and aft. She will have an impressive 10,000 nm range at 12 knots and a high capacity waste management system to support her autonomy.She is also designed to be silent on the water. Her original naval architecture allows stable gliding through the water. Her low drag and seamless lines are to ensure best levels of low noise and vibration.Furthermore, Project L will feature a retractable ballast – like a sailboat keel – to adjust stiffness, roll time, feel and stability according to conditions, swell and wind direction when at anchor.Guest capacity of Project L is flexible, depending on her owner's needs. She can accommodate 12 guests with 40 crew plus staff, but it’s possible to expand this up to a maximum of 36 guests and 50 crew.The yacht's interiors will be well-lit, as lots of natural light can flood in. Her lighting system will mirror the hue of natural light as the day passes, promoting wellness and calm on board.The exteriors of Project L will be linked to the interiors by one-way glass which reflects the seascape. Her only exterior light will run the length of the yacht, which can change colour to transform the reflections or her nighttime silhouette. A futuristic concept is now exclusively for sale with SuperYachtsMonaco.

Delivered this summer, the 90-metre Oceanco superyacht DreAMBoat made a splash at the Monaco Yacht Show 2019 with her international debut. Yesterday, the famous vessel was photographed at the shores of Gibraltar.Photo: @DannyWheelz on Instagram via Dutch YachtingAccording to social media sources, DreAMBoat was built for US billionaire and owner of the Atlanta Falcons NFL team Arthur Blank, who is valued at $5.5 billion by Forbes. Meanwhile, Forbes valued the team at $2.6 billion as of September, 2018.DreAMBoat at the MYS 2019.

The USA-based yacht builder Nordhavn presented a new project of a 45-metre research vessel Nordhavn 148. The vessel with designs from the Dutch studio Vripack was revealed at the recent Fort Lauderdale International Boat Show.The model will be the debut superyacht entirely built of metal in the brand’s history. She will also become the yard’s new flagship, displacing the 36.75-metre N120 model.Jim Leishman, Vice President of Pacific Asian Enterprises, Inc., which manufactures Nordhavns, says:We’ve talked about building a larger boat for a while now. It would be something specifically meant for the most challenging worldwide conditions.The ice class explorer needs is set to come out innovative in many ways for Nordhavn itself. The project is difficult to classify to a specific category, therefore, the shipyard speaks of it as a crossover, which combines the features of commercial ships and luxury superyachts.PAE looked to Vripack, with whom they’ve had a successful partnership on the interior design of the Nordhavn 80, to mentor the project and head up engineering. Vripack has overseen the design of the most notable of Northwest Passage-exploring yachts and have a rich, successful history of building in steel. Marnix Hoekstra, co-creative director at Vripack expressed:Nordhavn were keen to tap into our explorer heritage. Nordhavn boats are renowned for venturing to remote off-the-beaten-track destinations, and so the aim was to demonstrate to owners that this significant latest model has been conceived by a design studio that has a proven track record in this arena.Not many details on N148 have yet been disclosed. Key to the design are Vripack’s reinterpretation of particular features, including a flared, rounded bow, the yard’s interesting combination of square and round windows, and an industrial chic aesthetic.It is also known that the internal volume of the new model, designed for 12 guests and 10 crew members, will exceed at about 25% that of N120 (constructed of FRP), with 495 GT against 400 GT. The yard explains rejection to use FRP by lower costs and a shorter delivery time due to greater convenience in working with metal.The new Nordhavn 148 is expected to be built in less than two years. There is also a probability that the construction will take place in Europe, and not in China or Taiwan, where other Nordhavns are built due to the cheaper cost of the Asian assembly.

Italian engineering startup company iSpace2O has offered an interesting 'craft', with no analogues as of today. Named DeepSeaker DS1, it can dwell both above and below water. DeepSeaker is a multipurpose craft. The vessel can be deployed for leisure, tourism, search and rescue, research and other utilities.DeepSeaker DS1 is capable of diving to a depth of 50 - 100 meters, depending on the mode. To go underwater, it is necessary to fill the inflatable tank that plays the role of a ballast tank.Oxygen cylinders that allow people inside to breathe are not needed, since the Oxygen for the passengers will be extracted from sea water.According to the developers, this process requires minimum energy, which is important, since DeepSeaker DS1 is a 100% electric device.On the surface, equipped with water jets and foils, the DS1 is capable of speeds up to 30 knots under the most powerful performance. With two electric motors of 40 kW each, which are included in the basic package, the maximum speed capabilities are limited to 23–25 knots.Lithium-ion batteries guarantee six to eight hours of battery life. A full recharge of batteries takes eight hours, but there is also a quick charging system that allows you to manage in no more than an hour.The small size of the four-sear Deepseaker DS1 enables her to fit easily in a garage of any superyacht or support vessel. The owner is also entitled to personalise his model opting for a colour scheme in the style of a mothership.The standard equipment on-board the vessel includes a digital dashboard, connectors for iPad, GoPro cameras and even such peculiar devices as hydrophones, with which one can listen to marine inhabitants.According to Giuseppe Carusi, co-founder at iSpace2O, the project has existed for five years, but only now they received financing. The first prototype of DS1 is planning to attend the Dubai Expo in October 2020, while the final version of the prototype will be ready by early 2021.The price of DeepSeaker DS1, according to preliminary data, will vary from € 950 thousand to € 1.2 million, depending on the version. In the future, it is planned to develop a larger and more spacious version, based on the platform.
