The demand for very large sailing yachts is nothing like that for large motor yachts, but over the last few years there has been increased interest in very large sailing yachts. Some projects have been delivered, some are under construction and others are on the drawing board. <img src="https://photo-assets.superyachttimes.com/photo/271922/image/large-b991006523bd905dbed9b749b4cd42e1.jpg" data-gid="gid://syiq/Photo/271922">We ask a panel of experts – Bart van der Meer (engineering sailing systems at <a data-gid="gid://syiq/Company/458" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Rondal B.V.

It does, of course, present some interesting challenges, but Rondal has built its reputation on resolving challenges.&nbsp;Rob Doyle: For a 100-metre sloop in terms of length overall, no, it is not possible. For a 100-metre spar height, yes, that is possible. If someone says ’yes’ to a 100-metre LOA yacht they are out of their depth and have not fully researched all the options involved. At RDD we have done a huge amount of research on this question and we are one of the few naval architects and design studios that have an understanding of the complexibility of such a big rig. Class approval would be difficult, but they will lean hard on the naval architect’s calculations, research and experience.&nbsp;Thys Nikkels: When we are pushing boundaries with any aspect of a design the answer is always ‘Do your homework!’ If you do not have experience with a certain size or configuration you have to do the necessary research and development to prove the design is feasible. Feasible in concept, safe in construction and safe in operation, only then can you tell a client that it is possible, and to do that you have to work with a team of researchers, material specialists, builders to find the required solutions for the challenges.<img src="https://photo-assets.superyachttimes.com/photo/108433/image/large-6f7ee4bb350c7e7604865e0774d55463.jpg" data-gid="gid://syiq/Photo/108433">Are there any suppliers who would take the risk of building such a yacht?Bart van der Meer: We have already built three impressive 70-metre-plus &nbsp;rigs and are currently planning a large rig for an 85-metre sloop, which will become one of the world’s largest.Rob Doyle: There are two really only two manufacturers that can build big rigs. Rigging would be another significant difficulty, along with winches, systems, furling, hull structures, regulations and more.<img src="https://photo-assets.superyachttimes.com/photo/271932/image/large-fe57b0ec686c9fcbbe3f0f91922d0a1d.jpg" data-gid="gid://syiq/Photo/271932">Even if you could build it, would it be safe to operate for the crew?Bart van der Meer: Given the exceptional loads, risk factors for the crew are already an important factor in planning sailing systems for today’s largest sailing yachts, especially when racing. These loads and the sheer length and weight of running rigging do increase exponentially when looking at a rig for a 100-metre sloop. But we should keep in mind that, at this end of the superyacht fleet, only the most highly qualified and experienced crew would manage and trim the sail plan. They would do so with access to very sophisticated load sensors and safety triggers to ensure loads and risks remain within the design boundaries. There is also the possibility that these big rigs could be operated fully automatically. Especially as the cost related to fully automating a sailing system becomes smaller in comparison to the overall cost. However, this route could present new challenges of its own until fully proven.Rob Doyle: We will always design rigs with safe operation in mind, the numbers involved are huge and operation of a sail plan of this size would be very difficult, if not impossible. The size of the systems to control such a rig are significant and very detailed research is required, the sparmakers can build very big rigs – the limit is the yacht not the spar tube.&nbsp;Thys Nikkels: In the end, a large sloop will only work for the client if it can be safely and relatively easily operated by the crew. Otherwise the rig will never, or only sporadically, be used.<img src="https://photo-assets.superyachttimes.com/photo/236181/image/large-38e23873797382eff5e629953f24cb77.jpeg" data-gid="gid://syiq/Photo/236181">Have you had any requests for such a large project and do you expect that one day a client will decide to build one?Rudy Jurg: We have already been introduced to enquiries and concepts of this size that for one reason or another have yet to progress. I have little doubt that 100-metre-plus rigs will be built in the future. The first one will be commissioned by a very ambitious and visionary individual with deep pockets. Once this client’s project is afloat, others are more likely to follow.&nbsp;Rob Doyle: Yes, we have had requests for such yachts a number of times. What we explain first is that the jump from 78-metre M5 to a sloop with a spar length of 100 metres is enormous. If you have not designed and built big rigs before, then a client is very exposed. At RDD we have designed more big rigs, both sloop and ketches, than many other naval architects, but the numbers are staggering when you present the research and the real build numbers. <img src="https://photo-assets.superyachttimes.com/photo/272049/image/large-6060ad9c10f61da7535208d03e662ce4.jpg" data-gid="gid://syiq/Photo/272049">What are the cost implications of building a 100-metre sloop compared with a schooner of similar size?&nbsp;Bart van der Meer: One of the biggest cost implications is that most of the hardware needs to be designed from scratch for the sloop. Nothing on this scale is readily available on the market: no furlers, no toggles, no winches. And it needs to be designed not just bigger, but exponentially bigger. Take a runner winch, for example. From a 30-metre sloop to a 60-metre sloop, the retrieving length will double and the pull force goes from roughly 10 to 30 tonnes. If you want to be able to retrieve the runners at the same time, you’ll need four times more winch power to double the speed and more than double the force.&nbsp;When you recall it was considered doubtful if you could fly a spinnaker from the mast of a 100-foot sloop 30 years ago, we can see that the evolution of marine design technology has always innovated to address such issues. The expertise is there to make the rig of a 100-metre sloop happen, &nbsp;as long as it is accepted that substantial system development costs as well as the hardware manufacturing costs will bear heavily on the first project. For these reasons, it will certainly cost more than the rig of a 100-metre schooner or ketch.Rob Doyle: Hard questions because if you want to be the tip of the sword, a visionary owner that wants to reach for the stars and build the biggest sloop. But you may need to ask yourself: is the ketch a better option at the 100-metre LOA size?<img src="https://photo-assets.superyachttimes.com/photo/236173/image/large-d089b6d8c8cd89662da7e3fc43a4f62c.jpeg" data-gid="gid://syiq/Photo/236173">Given all the factors above and from your own experience, what is the ideal size for a super-sloop?Rudy Jurg: It is difficult to say there is an ideal size, though we do know that the ‘ideal’ size keeps on growing as larger yachts prove their reliability and their capacity to deliver exceptional lifestyle experiences and amenities to owners and their guests. Ultimately the ‘ideal’ will always be related to owners’ plans, their financial resources, their vision and ambition.Rob Doyle: I believe an 85-metre LOA sloop would be the limit, but there are different factors at play that have to be understood and it's more about the length/beam ratio than LOA, which would be a more suitable metric to start with. On the limit of tube lengths, you need to ask the spar maker for that number, but we are comfortable with the tube lengths we have spoken to clients and sparmakers about.This article was originally published in September 2022 of Issue 1 of the How to Build It magazine. <a href="https://superyachttimes.com/api/download/how-to-build-it-issue-1" target="_blank">You can download the entire magazine for free here</a>.

61m Feadship superyacht Samadhi for sale

The 61m Feadship superyacht Samadhi has entered the market in turnkey condition. 

Many energy commentators believe that hydrogen is the transport fuel of the future. But are fuel cells the answer to the yachting industry’s dependence on fossil fuels?Moored in her home port of Saint-Malo in Brittany, the 30-metre, hydrogen-powered catamaran <a data-gid="gid://syiq/Yacht/5044" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Energy Observer30.5m (100'1&quot;)Canadair1982">Energy Observer&nbsp;</a>is a hive of activity. It’s mid-February and the first energy self-sufficient vessel using renewable sources to produce hydrogen from purified seawater is just days away from embarking on a round-the-world voyage that will last four years.&nbsp;Having already racked up over 18,000 nautical miles since her launch in 2017, by the time you read this the floating smart-grid laboratory will be en route for Tokyo and the Olympic Games before moving on to California. <img src="https://photo-assets.superyachttimes.com/photo/186689/image/large-9f1327280a4370bf280d6935a26657a6.jpg" data-gid="gid://syiq/Photo/186689">Over the winter <a data-gid="gid://syiq/Yacht/5044" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Energy Observer30.5m (100'1&quot;)Canadair1982">Energy Observer</a>’s array of green energy technologies underwent a series of technical tweaks. A second fuel cell specially developed by Toyota and based on the same system in its hydrogen-powered car, the Toyota Mirai, was added to provide the vessel with an extra 114kW of power.&nbsp;The photovoltaic cells covering the deck and superstructure have been upgraded in collaboration with Solbian and the 202m2 of solar panels now provide an output of 34kW. The fixed pitch propellers have been replaced with automatic variable pitch props by Brunton to reduce drag, increase boat speed and enhance the generation of hydrokinetic power. <img src="https://photo-assets.superyachttimes.com/photo/186682/image/large-a486505339d92fb6209122b6ee418bdf.jpg" data-gid="gid://syiq/Photo/186682">The 12-metre tall OceanWings developed by Van Petegehem and based on the wing sails of America’s Cup trimarans were already in place, but the deck fittings, mechanics and automatic management software have been improved. The vessel is also fitted with two battery packs of 50kWh each, which are mostly used for peak shaving and can provide 10 hours of ‘get home’ power in an emergency.“Of course, these improvements still have to be thoroughly tested at sea,” says Hugo Devedeux, the development engineer on the project and a permanent crew member. “But even using the new fuel cell at 50 percent for optimised efficiency give us around twice the net power when you consider the original fuel cell was just 22kW. That meant there were times when we struggled with the wind on the nose and 20 per cent left on the batteries.” <img src="https://photo-assets.superyachttimes.com/photo/186690/image/large-e915d169255840b2df073b6821ee0907.jpg" data-gid="gid://syiq/Photo/186690">The tantalising attraction of hydrogen is that when consumed in a fuel cell to generate electricity, the only emissions are heat and water vapour. No greenhouse gases (GHGs) and no particulates. <a data-gid="gid://syiq/Yacht/5044" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Energy Observer30.5m (100'1&quot;)Canadair1982">Energy Observer</a>&nbsp;harnesses green electricity from solar and hydrokinetic sources to electrolytically split water molecules (H2O) and release the hydrogen, which is fed into a fuel cell to produce energy in an electrochemical reaction to power the vessel and onboard services. The heat produced during the process is recycled to provide hot water and onboard heating.&nbsp;The first fuel cell predates the first combustion engine, but the success and efficiency of the latter has largely confined hydrogen technology to space exploration and submarines. Until now. The urgent need to combat climate change and global warming has refocused attention on hydrogen as arguably the most viable path to decarbonisation and securing a more sustainable energy system. Indeed, Pierre-Etienne Franc, initiative secretary of the trade group Hydrogen Council, believes “The years 2020 to 2030 will be for hydrogen what the 1990s were for solar and wind.” <img src="https://photo-assets.superyachttimes.com/photo/186692/image/large-8bcf110727e606ab77fd7d7eeeb88e02.jpg" data-gid="gid://syiq/Photo/186692">Fuel cells are no longer a technology of the future: we now have cars, buses, trucks, trains and even aeroplanes powered by hydrogen fuel cells. Ship builders are also responding to GHG-reduction regulations targeting marine traffic. Yachting has been slow to relinquish its love affair with fossil fuels and even slower to pick up on the potential of fuel cell technology, focusing instead on hybrid solutions with batteries. Lithium-ion batteries can provide zero-emission propulsion for smaller vessels that operate with short duty cycles, such as small passenger ferries and lake service boats, but their power density and weight limit their use as a primary power source for large yachts.Let’s be clear: fuel cell propulsion is still very much in development and there are considerable obstacles to overcome before fuel cells can rival batteries on yachts, let alone diesel engines. One of the principal challenges associated with using hydrogen as a transport fuel is that it is difficult and expensive to store. If a fuel-cell car were to store the 1kg of hydrogen needed to drive 100km at atmospheric pressure, for example, the gas tank would have to be 11m3 in size. That’s why cars use compressed hydrogen gas, squeezing about 5kg into a carbon-fibre reinforced tank at 700 bar. Clearly, even a small displacement yacht requires much more fuel, and hence storage space, than a family car. <img src="https://photo-assets.superyachttimes.com/photo/186683/image/large-8068c8110200801b9641063c16a45e0a.jpg" data-gid="gid://syiq/Photo/186683">“A major difficulty we face is that current maritime legislation – or rather the lack of it – limits compression to 350 bar as opposed to the 700 bar for cars,” says Laurent Perignon of <a data-gid="gid://syiq/Yacht/5044" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Energy Observer30.5m (100'1&quot;)Canadair1982">Energy Observer&nbsp;</a>developments’ maritime division. “This poses a problem because at 300 bar the hydrogen storage tanks on a yacht need to be around fourteen times bigger than equivalent diesel tanks and five times the weight. At 700 bar we could at least reduce the volumetric mass by half.”Liquified hydrogen occupies less space and has a higher energy density than hydrogen gas, but it has to be stored at minus -253°C. Liquid hydrogen requires a complex (off-site) production plant, specially insulated tanks for storage and a lot of energy to maintain cryogenic temperatures. A very real risk is that the net energy provided by the liquid hydrogen would not offset the energy and expense it takes to produce, transport and store it. <img src="https://photo-assets.superyachttimes.com/photo/186693/image/large-65f71c2400ccfadeaa0ef2f8f2ad9d0e.jpg" data-gid="gid://syiq/Photo/186693">Some of these issues are highlighted by Aqua, the 112-metre superyacht concept by <a data-gid="gid://syiq/Company/926" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Sinot Yacht Architecture & Design (Company)">Sinot Yacht Architecture &amp; Design</a> in collaboration with <a data-gid="gid://syiq/Company/5009" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Lateral Naval Architects (Company)">Lateral Naval Architects</a> notable for its audacious design and liquid hydrogen propulsion (recent reports that Bill Gates had commissioned Feadship to build Aqua as “the world's first hydrogen-powered superyacht” were denied by Sinot). Lateral Naval Architects readily admit that technological readiness is at an early prototype level, but they fully recognise and support the need to transfer to alternative sources of fuel:“There is a key theme here, and that is electrification,” says the UK-based studio. “We believe that electrification is the gateway to fully exploiting the use of future fuels, cleanly produced via renewable energy.”<a data-gid="gid://syiq/Yacht/5044" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Energy Observer30.5m (100'1&quot;)Canadair1982">Energy Observer</a> produces its own hydrogen using electrolysis and renewable energy, but the industrial method is much less eco-friendly. Nearly all global hydrogen production is by steam methane reforming (SMR) that blasts natural gas with high-temperature, high-pressure steam. SMR requires fossil fuel input and leaves behind carbon dioxide as a waste product, so it is of little use for decarbonising the energy system. <img src="https://photo-assets.superyachttimes.com/photo/186684/image/large-a89d1446f00db7716178ef777de378b5.jpg" data-gid="gid://syiq/Photo/186684">Clean hydrogen made by electrolysis is now becoming more cost-competitive, helped by the plummeting cost of renewable energy, but as <a data-gid="gid://syiq/Company/5009" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Lateral Naval Architects (Company)">Lateral Naval Architects</a> point out: “The most significant barrier to the realisation of a full hydrogen superyacht is not the onboard technology, but rather the practical availability of green hydrogen within a global distribution network.”&nbsp;Regulations and infrastructure are other hurdles that need to be resolved if hydrogen propulsion is to have any hope of taking off. The <a data-gid="gid://syiq/Yacht/5044" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Energy Observer30.5m (100'1&quot;)Canadair1982">Energy Observer</a> team is working with <a data-gid="gid://syiq/Company/1463" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Bureau Veritas (Company)">Bureau Veritas</a> and <a data-gid="gid://syiq/Company/1452" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Lloyd's Register (Company)">Lloyd’s Register</a> to establish a set of safety criteria that the yachting industry can work to:&nbsp;“It’s a classic chicken and egg dilemma,” says Perignon. “Without operational guidelines in place, there can be no hydrogen refilling stations in ports and marinas. As the situation stands at the moment, a vessel storing more than one tonne of hydrogen would not be allowed into a commercial port. We urgently need regulations that are in step with the technology, and vice-versa.”<img src="https://photo-assets.superyachttimes.com/photo/186691/image/large-7cbc7c121ffb27b5d604c5e8ad4ca2fd.jpg" data-gid="gid://syiq/Photo/186691">The most realistic scenario today for implementing hydrogen fuel cells on a superyacht is to replace the diesel generators for servicing hotel loads, or the same generators in a hybrid set-up for low-speed auxiliary propulsion in zero-emission mode for manoeuvring in port or cruising protected waters where the use of diesel engines is prohibited. But these applications are likely to expand in the near future with the EU-funded group Hydrogen Europe predicting that hydrogen usage will become widespread by 2030. In this context, yachting has the opportunity to be in the first wave of pioneers. “We’re working with a private client on a new-build project with fuel-cell generators that should be ready in time for the 2021 <a href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Monaco Yacht Show - 2021">Monaco Yacht Show</a>,” says Perignon. “But what hydrogen propulsion really needs is other early adopters so the technology can move beyond the laboratory stage into real-life applications.”In the meantime, the <a data-gid="gid://syiq/Yacht/5044" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Energy Observer30.5m (100'1&quot;)Canadair1982">Energy Observer</a> team is collaborating on a hydrogen-powered boat that will take part in the Solar Energy Boat Challenge in Monaco from 30 June to 4 July.

Insight: Is Hydrogen the transport fuel of the future?

<a data-gid="gid://syiq/Company/23" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Lürssen Yachts (Company)">Lürssen</a> have announced the sale of their first superyacht with fuel cell technology. Peter Lürssen described at the recent Lürssen Live show how the company have been at the forefront of the innovation: “Since 2009 we have been involved in research projects aimed at using fuel cells on ships, and since 2012, the development of a modular fuel cell system using methanol has been underway – this is a project which runs under the name Pa-X-ell."<img src="https://photo-assets.superyachttimes.com/photo/193216/image/large-0a5ecd06386e6de1131b5141f73e603f.jpg" data-gid="gid://syiq/Photo/193216">Describing the science behind the innovation, Peter Lürssen explained “we have a partnership with Freudenberg, the leading company in maritime methanol fuel cells. The core element is a cell which consists of two bipolar plates and one membrane electrode-assembly, in between you build these cells, hundreds of cells are stacked to form a fuel cell stack. &nbsp;Several fuel cell stacks, the FC balance of the plant (compressor, DC/DC, etc.) and the fuel reforming unit, will be combined to a highly integrated fuel cell system. The fuel cell systems, which already meet the specific maritime rules, will be connected with the methanol supply system, the ventilation and electrical infrastructure. Then the magic can start, out comes electrical power and warm, moist air” as by-product.<img src="https://photo-assets.superyachttimes.com/photo/193220/image/large-5405f86acf2db399ff738b1cb7d2f3c5.png" data-gid="gid://syiq/Photo/193220">“Fuel cells have very little maintenance and are more efficient than a diesel engine, which is already a very efficient way to produce power. FC avoids nitrogen oxygen, soot and even CO2 when green methanol is used. It has one drawback which is the lower dynamic capability” this means there is a slightly slower response time. In order to avoid this, <a data-gid="gid://syiq/Company/23" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Lürssen Yachts (Company)">Lürssen</a> will combine the fuel cell with a battery bank and this makes up for this lower dynamic ability.<img src="https://photo-assets.superyachttimes.com/photo/193218/image/large-5949fef62ae7ced601b5d7055dd9a3c1.jpg" data-gid="gid://syiq/Photo/193218">In discussing whether this technology would truly be seen in the future, Peter Lürssen said; “contrary to our normal behaviour, we can tell you that we are building a superyacht with a fuel cell installed, we have an amazing owner who loves technology and new developments, and when we told him about it, he was very excited”. This fuel cell will allow him more than 15 nights emission free at anchor, or the owner will be able to slow cruise his superyacht for more than 1000 miles emission free “and it is actually very very exciting”.<img src="https://photo-assets.superyachttimes.com/photo/193215/image/large-c2978f33d62ef8cf98113c90cd6fef39.jpg" data-gid="gid://syiq/Photo/193215">With potential for application to custom yachts, the implications for the industry are monumental. As David Seal noted at the Lürssen Live show, this is a milestone in the yachting industry, and for Peter Lürssen it is a “clear signal that owners who are already investing a substantial amount into building yachts are willing to invest that extra bit of money to make that quantum leap of furthering propulsion technology on a yacht, this will be a game-changer”.<iframe width="640" height="360" src="https://www.youtube.com/embed/gnuLB_YkVdM?&amp;wmode=opaque" frameborder="0" allowfullscreen="" class="fr-draggable"></iframe>
