According to <a data-gid="gid://syiq/Company/151" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Southern Wind (Company)">Southern Wind</a>, she “will be the lightest performance cruiser in its range, delivering the perfect balance between high-performance and comfort.”&nbsp;As was the case with the builder’s SW108 Smart Custom yacht model, the SW123 sailing yacht is available in several keel configurations, sail plans, deck configurations (GT, X-Crossover) and interior layouts, depending on the owner's needs.<img src="https://photo-assets.superyachttimes.com/photo/351633/image/large-a991dd6741336cb0c261c412933043c1.jpeg" data-gid="gid://syiq/Photo/351633">The SW123 yacht’s hull shape has been imagined to host a twin rudder configuration in conjunction with either a lifting or telescopic keel, amounting to a draft of 3.85-metres with the keel raised."The generously wide aft sections and transom of the SW123 allow for more internal volume and deck area. This ample width is carefully balanced with extra volume in the forward sections to ensure the yacht remains in control with a level fore-and-aft trim when sailing at typical upwind heel angle,” Jim Schmicker of <a data-gid="gid://syiq/Company/152" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Farr Yacht Design (Company)">Farr Yacht Design</a> explained. <img src="https://photo-assets.superyachttimes.com/photo/351632/image/large-9acdadfdd4ea0e0311710d0fa30bb68c.jpeg" data-gid="gid://syiq/Photo/351632">Thanks to the yacht’s notably wide aft cockpit, two transom configurations are permitted. One such configuration is the twin-fold transom system, which converts the SW123’s aft section into a beach club plus a tender and toy garage that can house a nine-person tender of 5.35-metres. Meanwhile, the “Seaside Lounge” transom design provides a larger beach club and swim platform, paving the way for a more flexible lounge area."The <a data-gid="gid://syiq/Company/151" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Southern Wind (Company)">Southern Wind</a> 123 embodies the smart custom concept, offering a refined platform that allows for tailored deck geometry designs and interior styles to customise each yacht according to the owners desire and vision, while maintaining a proven structure. In this size range, its versatility in exterior architecture and styling, and in the interior functions, ensures a high-end yachting experience,” commented Massimo Gino of <a data-gid="gid://syiq/Company/153" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Nauta Yachts S.r.l.

Moreover, each of her guest staterooms can be imagined as multifunctional, serving as an onboard studio with a dayhead or a gym or sauna.The SW123’s main saloon is a single open space for 10 guests to unwind on the sofa, or for eight to 10 guests to enjoy meals at the dining table. When it comes to the crew area, the space can house five to six members in three ensuite cabins.&nbsp;Regarding her propulsion, the SW123 sailing yacht is available with <a data-gid="gid://syiq/Company/4531" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="International Maritime Organization (Company)">IMO</a> Tier III compliant traditional Diesel Propulsion, or can be constructed with a serial hybrid power and propulsion system with an integrated high-voltage energy storage system.

Ulstein began its thorium-powered Thor concept with a question: What if we could design and build a vessel with an abundant emission-free energy source able to support other vessels with clean fuel? There are some 160 vessels worldwide with nuclear reactors, nearly all of them military ships or submarines, but will we ever see a nuclear superyacht?<a data-gid="gid://syiq/Company/4539" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Ulstein Verft AS (Company)">Ulstein</a> first unveiled its 149-metre Thor concept in 2022 together with the full-electric cruise ship concept Sif. With carbon emissions and alternative fuels in the spotlight, the disruptive project garnered considerable industry interest and last year the Norwegian group was invited to join a panel of class societies and flag states to discuss nuclear energy at the Superyacht Forum during <a data-gid="gid://syiq/Company/4374" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="METSTRADE (Company)">METSTRADE</a> in Amsterdam. <img src="https://photo-assets.superyachttimes.com/photo/345476/image/large-86e6b7f074b0d025daacd8ef278312c7.jpg" data-gid="gid://syiq/Photo/345476">“What was interesting was that each session was given 45 minutes before breaking for lunch, but ours had a record show of people and lasted one-and-a-half hours,” says Øyvind Gjerde Kamsvåg, Chief Designer at <a data-gid="gid://syiq/Company/4539" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Ulstein Verft AS (Company)">Ulstein International</a>. “Most people were sceptical about nuclear power at first, but many were converted by the end of the session.” <img src="https://photo-assets.superyachttimes.com/photo/345475/image/large-fe152c3ab648f45f95a44efcbb814fa2.jpg" data-gid="gid://syiq/Photo/345475">The clever thing about Thor from a superyacht perspective is that it is categorised as a Replenishment, Research and Rescue (3R) vessel and conceived as a floating power and charging station. Equipped with a Micro Modular Reactor (MMR) or a thorium-powered Molten Salt Reactor (MSR), it would be able to generate 20MWe of clean, safe electricity for recharging a new breed of full-electric vessels at sea, with the potential to also be plugged into the renewable energy grid.&nbsp;“Thor would be able to satisfy a variety of different needs in the market,” continues Kamsvåg. “So you can use it as a first responder, you can use it as a scientific research hub, you can use it as an energy replenishing unit. It can serve so many functions once we start to explore the nuclear energy infrastructure.” <img src="https://photo-assets.superyachttimes.com/photo/345477/image/large-0429b7fc1a60397791907c4ab4370335.jpg" data-gid="gid://syiq/Photo/345477">The alternative to a mobile charging station like Thor is installing a nuclear reactor on board the yacht itself, which comes with other potential advantages. As the fuel is contained within the reactor there are no fuel tanks, combustion air intakes or exhaust stacks that take up valuable space. Besides being emission free, nuclear reactors require no regular maintenance and provide extremely long intervals of operation before refueling. The latest reactors on submarines, for example, are designed to last the lifetime of the ship, during which time they circumnavigate the globe many times. <img src="https://photo-assets.superyachttimes.com/photo/345478/image/large-14fd245191f94bb52f00df8512f04a23.jpg" data-gid="gid://syiq/Photo/345478">“Superyacht clients like the idea of Thor because the reactor is separate from the yacht itself,” says Kamsvåg. “But we’re starting to see micro reactors and associated systems that can be scaled to fit on bigger superyachts. That is still a bit further up the road, but I think both scenarios are equally interesting.”<img src="https://photo-assets.superyachttimes.com/photo/345479/image/large-d6d867f4205068d87c224002e1e073ca.jpg" data-gid="gid://syiq/Photo/345479">Theory of relativity&nbsp;<a data-gid="gid://syiq/Company/29" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Feadship (Company)">Feadship</a> considered the question with its Relativity concept back in 2012 and concluded that “technically speaking, a nuclear fission reactor design could be made, customised to fit the available space on a yacht and dimensioned to allow for all operating conditions.” Like <a data-gid="gid://syiq/Company/4539" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Ulstein Verft AS (Company)">Ulstein</a>, thorium was envisaged as fuel in a high-temperature, low-pressure molten salt reactor. The heat output would then be converted to mechanical power using high efficiency, closed-cycle Helium gas turbines to drive the generators. But the technology was not readily available and issues associated with insurance and port controls rendered the idea compelling but ultimately impractical. More recently, a 2023 joint study between the <a data-gid="gid://syiq/Company/29" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Feadship (Company)">Feadship</a> R&amp;D department and Delft University tackled the topic again.<img src="https://photo-assets.superyachttimes.com/photo/345484/image/large-79faf9b85628a8a8924851eb64797f28.jpg" data-gid="gid://syiq/Photo/345484">The study identified that a IV generation Micro Modular Reactor using a uranium, carbon and oxygen fuel kernel might be the best fit for the load profile of a superyacht. A fraction of the size of a conventional nuclear reactor, MMRs can be factory-assembled and transported as a unit for installation.

However, the <a data-gid="gid://syiq/Company/29" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Feadship (Company)">Feadship</a> study underlined the massive weight implications of the lead and concrete shielding materials required.

This view was backed up by Ronno Schouten, Design Manager at <a data-gid="gid://syiq/Company/29" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Feadship (Company)">Feadship</a>, at the Alternative Fuels conference during the 2024 Monaco Energy Boat Challenge:<img src="https://photo-assets.superyachttimes.com/photo/345483/image/large-fce43549aacd84d60dd04bab4f6b42ee.jpg" data-gid="gid://syiq/Photo/345483">“Yes, a nuclear-powered yacht will be technically feasible sometime in the future, but why integrate an MMR with an average onboard load of about 10 percent, when you can put it to better use onshore making green fuel like methanol for multiple yachts at maximum power?”<img src="https://photo-assets.superyachttimes.com/photo/345481/image/large-613ba1e28b699b2098c84884a05656cc.jpg" data-gid="gid://syiq/Photo/345481">High stakes&nbsp;Although technically possible, onboard nuclear power faces other hurdles. Public perception of the danger of radioactivity, heavily influenced by high-profile accidents like the Chernobyl and Fukushima disasters, is a major concern although sometimes overstated. The latest nuclear technology makes leakage or meltdown highly unlikely, but checks need to be put in place to prevent accidents due to grounding, impact, collision, machinery damage, fire, explosion, and other causes. Last but not least is the near total lack of maritime legislation, insurance policies and flag state rules covering nuclear reactors on yachts.“The regulatory bodies and flag states all agree that nuclear will play a role if we want to go into emission free or more sustainable shipping,” says Jose Jorge Garcia Agis, Managing Director at <a data-gid="gid://syiq/Company/4539" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Ulstein Verft AS (Company)">Ulstein International</a>. "The main challenge today is that the international regulations for nuclear-powered ships are outdated and based on old nuclear technology. This makes it very difficult to implement them on modern vessels. Ship design is heavily influenced by regulations; we work within the rules. Without clear rules, we have to define our own framework and then seek approval, rather than designing around an existing framework."<img src="https://photo-assets.superyachttimes.com/photo/345487/image/large-d4c783c0accbd70aef80541d535d2483.png" data-gid="gid://syiq/Photo/345487">The commercial shipping industry is aware of what is at stake.

A demonstration vessel designed to serve also as a passenger ship, she was appointed with 30 air-conditioned ensuite staterooms, dining facilities for 100 passengers, a lounge that could be converted into a movie theatre, a swimming pool, veranda and library. However, high operating costs, low commercial value, limited port access and public concerns about safety led to her being taken out of service in 1971.<img src="https://photo-assets.superyachttimes.com/photo/345485/image/large-2718607a22e7678dd1cb76030ebc511a.png" data-gid="gid://syiq/Photo/345485">Sixty-five years after the launch of NS Savannah, the situation is very different.

Moreover, geopolitical tensions around the world are making the energy independence offered by the nuclear option an increasingly attractive proposition. In this scenario, another Norwegian research project, NuProShip (Nuclear Propulsion of Merchant Ships), is aiming to develop a commercially viable nuclear technology for ships that satisfies all stakeholders and requires no subsidies after the initial development process.&nbsp;Heading up the NuProShip project is Jan Emblemsvåg, professor of ocean operations and civil engineering at the Norwegian University of Science and Technology (NTNU). He believes that given the poor energy density of other low- and zero-carbon fuels we might not have much choice but to embrace nuclear power for ocean-going vessels, and draws on a very graphic example to make his point: if hydrogen’s energy density was one metre long, uranium would be 32 kilometres long and thorium would be 38 kilometres long.“This is what the green transition must be about,” he says. “We need to learn how to deal with these two atoms and then we should be just fine.”This article was featured in&nbsp;<a href="https://www.superyachttimes.com/magazine/how-to-build-it-issue-6" target="_blank">Issue 6 of How To Build It.</a>&nbsp;You can read all the articles from this edition&nbsp;<a href="https://www.superyachttimes.com/magazine/how-to-build-it-issue-6" target="_blank">here</a>, and stay up-to-date with all previous editions&nbsp;<a href="https://www.superyachttimes.com/magazine" target="_blank">here</a>.

This is as relevant for crew as it is for guests as noise impacts not just on our comfort, but also on our performance and can induce irritability, lack of concentration and errors in judgment. What constitutes annoying noise, from low-frequency booming to high-frequency hissing, varies from person to person, but it’s not completely subjective and <a data-gid="gid://syiq/Company/1457" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="RINA (Company)">RINA</a> – like other Class societies – has specific thresholds for its Comfort Class notation.“Being able to offer the quietest environment possible with low vibration, and without sacrificing seagoing performance, has become a determining factor of onboard comfort,” says Matteo Magherini, <a data-gid="gid://syiq/Company/1457" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="RINA (Company)">RINA</a>’s Yachting North Europe Business Development Manager. “The main objective of our consulting service is to attain all of this without increasing weight and costs or restricting the vessel’s operations, which is why we have a five-person team dedicated solely to noise and vibration prediction and analysis.”<img src="https://photo-assets.superyachttimes.com/photo/344579/image/large-d6075967e235334995600ca64689efde.jpg" data-gid="gid://syiq/Photo/344579">The N&amp;V team’s remit goes beyond Finite Element Models and Computational Fluid Dynamic calculations to assess noise and vibration levels early in the design cycle; it can also help to formulate contract specifications and design choices, adjust insulation and structural plans to achieve specific goals, carry out on-site inspections during construction work, compare results amongst similar builds, and propose the best cost-benefit solutions.“Powerful software has made the measurement and prediction of noise and vibration much more accurate,” says Elisa Fassola, a naval architect, marine engineer, and noise and vibration engineer at <a data-gid="gid://syiq/Company/1457" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="RINA (Company)">RINA</a> headquarters in Genoa who oversees the development of new regulations and provisions at the design stage. “But just as important is experience when to comes to formatting these digital tools and assigning the many sources of noise and vibration, from main engines and thrusters to pumps and pressure pulses from the props. Because <a data-gid="gid://syiq/Company/1457" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="RINA (Company)">RINA</a> has surveyed thousands of vessels, we have a huge database we can draw on.”<img src="https://photo-assets.superyachttimes.com/photo/344580/image/large-19d3c2821cfdc40e102aceb1a81e24e7.jpg" data-gid="gid://syiq/Photo/344580">All at seaWorking to a general arrangement together with noise insulation and structural plans, the <a data-gid="gid://syiq/Company/1457" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="RINA (Company)">RINA</a> team builds up a 3D model of the yacht using ESI VA ONE, a vibro-acoustics simulation software, to represent the enclosed volumes or cavities and the dynamic properties of the structure. The software relies on Statistical Energy Analysis (SEA), which is used routinely in the aerospace and automotive industries for predicting the transmission of sound and vibration through complex structural acoustic systems.&nbsp;In standard cases five main sources of noise and vibration are assigned – main engines, gearboxes, diesel generators, propellers, and the HVAC machinery – but these can be varied on request. The system then comes up with a noise distribution map showing how the noise is propagated in each area or cavity throughout the yacht. The software can also identify the main contributors of noise and at what frequency. Once the source has been localised, acoustic insulation can be improved where it’s needed most, or removed where not required. &nbsp;<img src="https://photo-assets.superyachttimes.com/photo/344586/image/large-b1c3e7511c1738be614b8fb41876430c.jpg" data-gid="gid://syiq/Photo/344586">As the technologies have advanced, so have tools at <a data-gid="gid://syiq/Company/1457" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="RINA (Company)">RINA</a>’s disposal. Software add-ons include ray tracing, a method for calculating the path of sound waves through a system with boundaries that have different absorption and reflection characteristics. Under these circumstances, analysis is complicated by sound waves that may bend, change direction or bounce off surfaces.&nbsp;“SEA is very good for interior noise prediction, but ray tracing works for external noise prediction,” explains Fassola. “For example, we can foresee how noise from the engine room ventilation ducts may propagate into the aft cockpit, or in the case of a yacht in a marina that is still running generators, how much exhaust noise will be heard by those on neighbouring yachts. Equally important, ray tracing is one method for studying underwater noise pollution and its effect on marine life.”SEA and ray tracing simulations can also be used to improve insulation (especially floating floors) and damping plans to reduce structure-borne noise emitted by thrusters during dynamic positioning. Additionally, propagation of noise and vibration on a displacement vessel is influenced by the surrounding water. Water affects sound waves in several ways; they move several times faster through water than air, for example, and travel longer distances. However, because the human ear evolved to hear in air, water tends to muffle sounds that are otherwise clear in air. Movement of the yacht through the water causes the fluid near the interface to accelerate and, in turn, to exert an opposing force on the hull. This is called hydrodynamic or added mass and software can calculate its effect on noise and vibration based on the boundary element method.<img src="https://photo-assets.superyachttimes.com/photo/344583/image/large-6cf0c4301e7c0d185a9b64e321bc25fc.jpg" data-gid="gid://syiq/Photo/344583">Visualising noiseWhen we think about onboard comfort and sound insulation performance, we also have to consider acoustic privacy requirements between two areas with a common partition. For example, if guests are watching TV in one cabin, it should be in inaudible in the adjoining cabin. The same goes for overhead impact noise from the footfall of people walking on deck, or the Jacuzzi pumps and plumbing.&nbsp;<a data-gid="gid://syiq/Company/1457" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="RINA (Company)">RINA</a> can test different insulation solutions using ESI NOVA, a software prediction tool based on the Transfer Matrix Method (TMM) for modelling absorption/transmission loss of acoustical systems. This can also be done on site when the yacht is in build to ensure predicted decibel levels are on target. Two types of wall panel, for example, may transmit the same volume of sound but have a different transmission loss curve. The transmission loss can also be rendered as a sound file to highlight the difference between the insulated and uninsulated ambience. &nbsp;<img src="https://photo-assets.superyachttimes.com/photo/344587/image/large-cc3f8f2db5e8f5f2a12ce963e913c6ef.jpg" data-gid="gid://syiq/Photo/344587">Acoustic cameras are relatively recent innovations that can detect the source of a noise and make it visible. <a data-gid="gid://syiq/Company/1457" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="RINA (Company)">RINA</a> uses an apparatus by Aesse Ambiente with an array of 112 microphones. As simple to use as a smartphone, it locates sound sources in real time and displays the results on the screen at 100 fps. On one yacht project the <a data-gid="gid://syiq/Company/1457" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="RINA (Company)">RINA</a> team was brought in to measure acoustic privacy and discovered a source of excessive noise between the dividing bulkhead and ceiling.“It turned out that a Roxtec fire seal had been left open and was the conduit for the noise,” says Elisa. “Using the acoustic camera we were able to pinpoint where the noise was coming from without having to dismantle or destroy anything.” <img src="https://photo-assets.superyachttimes.com/photo/344584/image/large-a8543fdc63c165563552e81eb54d36ce.jpg" data-gid="gid://syiq/Photo/344584">Sound in motionMotion amplification is another technique that uses video and image processing to detect subtle vibrations and make them visible to the naked eye. <a data-gid="gid://syiq/Company/1457" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="RINA (Company)">RINA</a> uses US-based RDI’s proprietary motion amplification cameras, software and algorithms. Accelerometers and strain gauges are traditionally used to detect and relay traditional vibration data, but being able to actually see vibration problems rather than just looking at numbers and charts makes it much easier to understand the interrelationships and causes creating the motion. Clearly useful for identifying mechanical problems and faults in the engine room, the <a data-gid="gid://syiq/Company/1457" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="RINA (Company)">RINA</a> team more often uses the technology to resolve issues of vibrating furniture in cabins.“We use the motion amplification camera a lot on cruise ships, where guests often complain about vibrating TV screens and lamp fixtures,” says Fassola. “There was one case where we recorded a wall lamp that was vibrating at 13Hz and 11mm per second, which is a lot!”Instead of having to glue dozens of accelerometers to pieces of furniture, the amplified motion of the vibrating lamp was immediately apparent. The problem was how the lamp was attached to the bulkhead and a better solution was quickly found requiring minimal downtime and expense. &nbsp;&nbsp;“We can predict a lot of potential issues today that a decade ago were a question of trial and error,” concludes Fassola. “Sometimes we come across unexpected – and unpredictable – sources of hydrodynamic noise, but often these are only noticeable because the rest of the yacht is so quiet!”<img src="https://photo-assets.superyachttimes.com/photo/344581/image/large-1a17ea01d957a9b14190ecece13eed75.jpg" data-gid="gid://syiq/Photo/344581" style="box-sizing: inherit; border: 0px; font-family: &quot;Open Sans&quot;, sans-serif; position: relative; max-width: 100%; margin: 1rem 0px; color: rgb(0, 0, 0); font-size: 13.6px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: rgb(255, 255, 255); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">Underwater noiseThe generation and propagation of underwater noise, mostly from propeller cavitation, is an emerging field of research due to its harmful effect on marine mammals. The International Workshop on Shipping Noise and Marine Mammals, held in Hamburg back in 2008, highlighted that low-frequency noise from shipping has been doubling approximately every decade. A modern cargo vessel may emit around 190 decibels of underwater noise – louder than a jet engine at take-off – and noise travels four times faster in water than air.&nbsp;Mapping the distribution of global underwater noise emissions from shipping shows that few areas of the oceans are unaffected, but regulations are becoming increasingly stringent, especially in protected regions of special environmental value such as the Arctic.

Aimed primarily at commercial shipping, owners and shipyards can decide to achieve the standard in normal seagoing conditions (Dolphin Transit Ship) or at 10 knots (Dolphin Quiet Ship), or both. In accordance with ISO standard 17028-1 for deep water, the underwater radiated noise is measured with a hydrophone array positioned at a specific distance from the passing vessel at a minimum seabed depth of 150 metres. <a data-gid="gid://syiq/Company/1457" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="RINA (Company)">RINA</a> aims to introduce a new procedure for shallow water measurements in accordance with the new ISO standard 17028-3 and will be based on measurements carried out by Port of Vancouver, which is home to various species of whale, dolphin and sea lion. <img src="https://photo-assets.superyachttimes.com/photo/344585/image/large-7cabe79ba5c6f01c2e0c4169031600ae.jpg" data-gid="gid://syiq/Photo/344585">Dolphin notation has not yet been awarded to any superyacht, mainly because their underwater exhaust systems are too noisy to meet the recommended guidelines.&nbsp;This article was featured in&nbsp;<a href="https://www.superyachttimes.com/magazine/how-to-build-it-issue-5" rel="noopener noreferrer" target="_blank" title="">Issue 5 of How To Build It.</a>&nbsp;You can read all the articles from this edition&nbsp;<a href="https://www.superyachttimes.com/magazine/how-to-build-it-issue-5" rel="noopener noreferrer" target="_blank" title="">here</a>, and stay up-to-date with all previous editions&nbsp;<a href="https://www.superyachttimes.com/magazine" rel="noopener noreferrer" target="_blank" title="">here</a>.
