Ecopoint

Ecopoint

The Ecopoint represents the total potential environmental load of a product or solution: it is a cumulative, more holistic value that includes the impacts on human health, the ecosystem and resource diversity. The single numerical score of Ecopoint represents the overall impact of a product or solution. This score can be interpreted as a measure of sustainability performance, where lower scores indicate lower environmental impact.

The Ecopoint therefore allows us to group the 9 other environmental indicators in three different categories of damage: (1) Human Health, (2) Ecosystem quality and (3) Resources. This way, obtaining a single score representing the total environmental impacts during the product's life cycle is possible.

Human Health and Ecosystem Impact

The ecopoint index factors in the impact on human health and ecosystems, how a product's life cycle may affect human well-being including health risks related to exposure to pollutants, and how it may impact ecosystems, including biodiversity and habitat disruption.

Resource Diversity

This takes into account the diversity and availability of natural resources, as well as the potential depletion of non-renewable resources and the consequences for future generations.

The Ecopoint index is essentially a form of multi-criteria assessment that allows decision-makers to weigh different environmental and sustainability factors. It acknowledges that environmental issues are interconnected, and a single value can provide a more comprehensive understanding of the trade-offs and impacts associated with a product.

Photochemical Oxidation

Photochemical Oxidation

On Earth, pollution mixed with heat and sunlight creates a concentration of Ozone (O3 gaz) in the atmosphere (stratosphere + troposphere). This gaseous element, when released in the stratosphere, acts like sunscreen for all living organisms, shielding the Earth’s surface from most of the sun’s UV light (unless it creates depletion in the atmospheric layer).

However, when this concentration remains at ground level in the troposphere, it affects the air that we breathe as humans and therefore starts becoming a health hazard. When inhaled, ozone reacts chemically with many biological molecules in the respiratory tract, leading to a number of adverse health effects.

We call this secondary air pollution Photochemical Oxidation, also known as Summer Smog. Chemically speaking, photo-oxidant formation is a photochemical creation of reactive substances: it is formed in the atmosphere by nitrogen oxides and volatile organic compounds in the presence of sunlight, often the consequence of emissions from fossil fuel combustion. POP calculates the destructive effects of ozone in the troposphere over a time horizon of 100 years.

X
Global Warming

Global Warming

The Earth receives energy from the sun through solar radiation, with about half of this energy being absorbed by the earth’s surface. The other half is reflected back into the atmosphere as infrared radiation or heat. Greenhouse gases (GHGs) trap this radiation in the atmosphere, thereby heating the Earth. Consequently, the more GHGs that are present in the atmosphere, the warmer the Earth’s temperature becomes. This process is known as the greenhouse effect.

In order to make meaningful comparisons between GHGs, scientists have adopted CO2 as the benchmark for measuring their heat-trapping abilities. CO2 is a clear, odourless gas produced during carbon combustion and in the respiration of living organisms. The heat-trapping potential of a gas, measured against CO2 over a fixed period, is known as Global Warming Potential (GWP). CO2 is used as a benchmark to measure the GWP of substances, which is expressed in kg of CO2eq.

Ultimately, GWP evaluates the potential impact of different gaseous emissions on climate change by calculating the radiative force over a 100-year time horizon.

X
Ozone Layer Depletion

Ozone Layer Depletion

In the stratosphere, an ozone-rich layer called the Ozone layer exists. The formation of the ozone hole is directly linked to the stratosphere’s temperature. Once temperatures drop below -78°C, polar stratospheric clouds tend to form, exacerbating ozone depletion over both of the Earth’s hemispheres.

The Ozone layer acts like sunscreen for all living organisms, shielding the Earth’s surface from most of the sun’s UV light. Its depletion could cause serious damage for humans, animals, plants and materials. Ozone Depletion Potential (ODP) calculates these destructive effectives over a time horizon of 100 years.

X
Acidification

Acidification

Acidification is an environmental problem caused by acidified rivers/streams and soil due to anthropogenic air pollutants such as ammonia, nitrogen oxides and sulphur dioxide. When acids are emitted, the pH factor falls and acidity increases, which for example can involve the widespread decline of coniferous forests and dead fishes in lakes in Scandinavia.

In the ocean, we define acidification as a reduction of the pH over an extended period of time, and it is caused primarily by an uptake of carbon dioxide (CO2) from the atmosphere: the ocean absorbs the extra amount of CO2 emitted in our atmosphere. We are already observing this change in the deep ocean, especially at high latitudes.

It affects marine organisms, with a consequence on the ecosystems they belong to in and above water: disrupting the food chain (increase of the mobilisation and the leaching behaviour of heavy metals in soil), altered prey availability (for example, krill for whales), impact on habitats (lower pH destroys coral reefs), but also the amplification of noise pollution by a modification of the underwater acoustics.

As an indicator, Acidification Potential calculates the impact of the potential change in acidity in the soil due to the atmospheric deposition of sulfates, nitrates, phosphates, and other compounds.

PM10

PM10

Dust from roads, farms, dry riverbeds, construction sites, and mines are types of PM10: particulate matter with a diameter of 10 micrometres or less. These are coarse (bigger) particles, which can irritate your eyes, nose, and throat. While fine (smaller) particles (PM2.5) are more dangerous and penetrate into the deep parts of your lungs — or even into your blood, it is important to measure the level of PM10 into the surrounding air.

Scientists have defined that a level of PM10 below 12 μg/m3 is considered healthy with little to no risk from exposure. If the level goes to or above 35 μg/m3 during a 24-hour period, the air becomes unhealthy, causing a risk exposure for people with existing breathing issues such as asthma or lung diseases.

With deposits accumulating onto surfaces, including vegetation, soil, and water bodies, PM10 also impacts soil erosion, water quality, aquatic life cycles, and can carry contaminants into ecosystems. It can lead to winter smog.

Water Scarcity Footprint

Water Scarcity Footprint

The water scarcity footprint helps assess how particular water use contributes to or exacerbates water scarcity in a given area. We assess this impact by considering the quantity of water consumption and the water stress index (WSI) of the region from where the water is extracted, to determine the impact of freshwater consumption in view of its deprivation potential.

Water Stress Index for yachting

In yacht manufacturing for example, water consumption is significantly high for the extraction and production of materials. The amount of water consumed when producing yacht-building material is more than double than during the operating phase of the yacht. Further, hull construction requires water in various stages such as composite-moulding process, curing resins, and more. While these stages do not use large volumes of water individually, they become high over the course of yacht production. The water stress index can thus be an important metric in quantifying how much water is consumed and identifying hotspots where efforts to minimise water use can be implemented.

The Water Stress Index takes into account factors like available water resources, population, and industrial demand for water in that area. Of course, water resource exploitation may have a different impact depending on the extraction area.

Water scarcity impact

If the water scarcity impact is high, it indicates that your product or solution is exerting considerable strain on an already water-stressed region. Consequently, it may be prudent to explore more sustainable water sourcing or conservation measures to mitigate one’s heightened environmental damage. Conversely, if the water scarcity impact is low, it suggests that your product or solution exercises a relatively minor impact on water scarcity in that region, which can be a positive indicator of sustainability.

The indicators for WSI reflect the cumulative amount of direct and indirect emissions to help us understand how a product or solution’s water use might impact water shortages.

X
Eutrophication

Eutrophication

Eutrophication calculates the destructive effects of ammonia, nitrates, nitrogen oxides and phosphorus (emitted in air and waters) on freshwater systems. In inland waters, it is one of the major factors that determine the ecological quality of an aquatic environment.

This process of pollution occurs when a lake or stream becomes over-rich in plant nutrient – as a consequence, phytoplankton increases, and the water becomes overgrown in algae and other aquatic plants. The plants die and decompose, robbing the water of oxygen so that ultimately the lake, river, or stream becomes lifeless.

While eutrophication occurs naturally in freshwater systems, man-made eutrophication occurs over millions of years and is caused by organic pollutants from man’s activities, like effluents from industries and homes.

X
NOx

NOx

NOX are a group of highly reactive gases produced by various natural and anthropogenic (human-caused) sources. They strongly affect the air quality in our immediate surroundings, leading to the formation of ground-level ozone and fine particulate matter, and contributing to acid rain or deposition, ozone depletion, and eutrophication of soil and water.

We know that the subsequent impacts of acid deposition and eutrophication onour soil and water can be significant, having adverse effects on aquatic ecosystems in rivers and lakes, damage to forests, crops and other vegetation. Furthermore, by contributing to the formation of atmospheric aerosols and particulate matter, NOx emissions can lead to the formation of nitrous oxide (N2O), a potent greenhouse gas that contributes to global warming and affects human respiratory systems. When the environment is affected by NOx, it results in Summer smog, Winter smog, and Acidification in the environment impacted by its release.

X
SOx

SOx

Sulphur dioxide (SO2) is a colourless gas with a pungent odour, released into the atmosphere from both natural sources, such as volcanic eruptions, and anthropogenic (human-caused) sources emitted by the combustion of fuels containing sulphur.

Sulphur dioxide is a pollutant that contributes to acid deposition, which, in turn, can lead to potential changes in soil and water quality (eutrophication due to excessive nutrient input, as discussed above). Its effects can be counterbalanced by implementing flue gas desulfurization systems in power plants, and regulations on emissions from transportation sources. Winter smog and acidification are among the results of its presence in our atmosphere.

Environmental Crew Guidelines out now: reducing energy, waste, & water impact onboard superyachts

Environmental Crew Guidelines out now: reducing energy, waste, & water impact onboard superyachts

Version 1 of the Environmental Crew Guidelines has officially been launched, marking a pivotal moment in steering the yachting fleet toward more sustainable practices. This comprehensive guide, highlighting best practices written for-and-by crew, offers information and inspiration for eco-friendlier behaviour onboard yachts.

As a collaborative effort between Water Revolution Foundation, initiator MB92, and creator Danella Hopkins (formerly of S/Y Black Pearl), this free and open-source tool offers 24 distinct sections providing crews with a detailed, holistic overview of how to adopt more conscious practices into their daily routines. Contributions from industry experts and crew members alike have ensured that a diverse range of perspectives and experiences are included. As a first version, the aim is to collect feedback and additional best practices from crew to expand on the content and launch a Version 2 in the future.

Powered by industry leaders

To ensure the widespread adoption of these guidelines and enable a united, coordinated action, industry trailblazers MB92, Burgess, Damen Yachting, Divergent Yachting, Feadship, Fraser Yachts, Heesen Yachts, Lürssen, Oceanco, Safe Harbor Marinas, Sanlorenzo, The Crew Network, The OM, Virtual Pursers, Y.CO, and YPI Crew have pledged their commitment as official supporting companies. S/Y Black Pearl and MY Savannah have also come onboard as ambassadors within the fleet. The dedication of these organisations distinguishes them as true change agents, guiding the way forward for a more eco-friendly yachting sector.

”These clear guidelines are applicable to every size and type of yacht operation and by sharing them with our crews as part of our fleetwide sustainability efforts, we hope to provide a strong foundation for better onboard environmental practices and show that any yacht, regardless of its size or build, can make a big difference in little ways,” shares yacht management company Y.CO.

Addressing yachting’s environmental impact

While many technical and digital solutions have already been introduced to drive the superyacht industry’s energy transition, these developments address only one facet of the challenge. A transition in onboard practices is also crucial:  “There are immediate actions that crew can take on board to introduce more environmentally-friendly practices, which can significantly reduce emissions (by up to 30%), whether by optimising temperature settings, making slight adjustments to cruising speeds or employing effective resource management,” says MB92.

Therefore, this initiative will provide crew with an extensive knowledge base and practical tools in order to foster a concrete shift toward sustainable superyacht operations.

Inside the guidelines

Organised under three overarching themes – ‘Onboarding Guidelines,’ ‘General Guidelines,’ and ‘Departmental Guidelines’ – this document caters to crew at every level. The onboarding guidelines emphasise ways in which crew can cultivate an environmental mindset and commit to improved operational practices. Fundamental principles and standards applicable to all crew members in their daily tasks are outlined in the general guidelines, while the departmental guidelines delve deeper, addressing the unique needs and individual responsibilities of each department. “We understand that environmental sustainability can be challenging to accomplish onboard and there is no one-size-fits-all approach,” states Executive Director of Water Revolution Foundation, Robert van Tol. “By working together with crew, we hope to inspire and facilitate this powerful group to minimise their yacht’s daily footprint where possible.”

To ensure proper enforcement onboard, the guidelines introduce the nomination of an “Eco-Sustainability Ambassador” (ESA). This dedicated crew member will collaborate with Heads of Departments (HODs) to streamline processes and drive the implementation of initiatives by supporting crew, monitoring progress, and reporting achievements.

“Our industry can collectively create lasting change in its outlook and operations by working together, and these guidelines will help yacht crews and shoreside management teams reduce their environmental impact through improved efficiency and better practices,” states Burgess. “When passionate individuals are given the chance to do the work they believe in, good things can happen, and in this way, we are committed to building a more environmentally aware and responsible industry.”

Designers’ Protocol unveiled to provide yacht design community with guiding sustainability principles

Designers’ Protocol unveiled to provide yacht design community with guiding sustainability principles

The Designers’ Protocol was launched at this year’s Monaco Yacht Show to present the industry with a standardised document aiming to provide designers with guiding sustainability principles. 

This collaborative effort, initiated by Dickie Bannenberg of Bannenberg & Rowell Design and co-created with Water Revolution Foundation’s Sustainable Yacht Design Taskforce, aims to inspire the broader yachting community and set out high-level issues for clients to consider when planning a new build. 

A roundtable discussion between top yacht designers and naval architects took place to share insights on the protocol and emphasise the importance of industry collaboration for achieving a sustainable future. Representatives on the panel included founder of Bannenberg & Rowell, Dickie Bannenberg; Philippe Briand, founder of Vitruvius Yachts; owner of Espen Oeino International, Espen Oeino; and Robert van Tol, Executive Director of Water Revolution Foundation. Editor in Chief at Superyacht Times, Francesca Webster, hosted and moderated the session.

INFLUENCES
The protocol has been developed based on the acronym ‘INFLUENCES,’ where each letter outlines different opportunities and aspects of various sustainable design principles.  There are 10 primary topics of interest, including operational profile, hotel load, decking solutions and more. The document contains concrete, visible output provided by the valued members of the Design Taskforce, which was initiated at the 2021 edition of Monaco Yacht Show. 

“Yacht- designers and naval architects are, in many cases, the initial point of contact with clients wishing to build or refit a yacht. As such, they have considerable influence on steering their clients towards responsible decisions. The INFLUENCES protocol sets this section of our industry on a clearer path to informing and guiding,” shared Bannenberg when asked about the importance of such a document for the industry. 

Eco-friendly approach to yacht design

As it becomes increasingly crucial to reduce yachting’s environmental impact, this initiative takes a significant step forward by promoting responsible and sustainable practices: “Designers are setting the precedent for expectations across the entire industry,” remarked Oeino. “This protocol should be compulsory as part of any client presentation so that we can instigate that dialogue and trigger a very healthy discussion surrounding sustainable design.”

Industry collaboration
This initiative stands as a testament to the industry’s commitment to harnessing collective expertise and experience, transcending individual interests for the greater good of achieving sustainability in yacht design. Collaboration is key in order to take coordinated, constructive, and significant steps forward. Through a joint effort, the field’s leading players are uniting to chart a course towards a more environmentally conscious yachting industry. “We must group our efforts to progress toward a solution. This protocol represents the first time we can show that, as naval architects and designers, we are on the same page regarding this challenge of sustainability,” offered Briand. 

Dickie Bannenberg also emphasised the importance of industry cooperation for this endeavour: “With a subject as broad – and often ambiguous – as sustainability, collaboration can be a powerful tool. There are several valuable and important initiatives within the yachting industry concerning the health of the oceans, from pathways to alternative fuels, but the Designers’ Protocol is, I believe, the first to connect designers and naval architects behind a united message.”

Next steps

“It’s all about sharing experience and data through broad collaboration. It’s not just a great initiative – it is indispensable that we do it. We must do it for the future of our industry, clients, and children. We encourage everyone to actively take part in this,” offered Oeino as a final thought.

Environmental Crew Guidelines preparing to launch: building support from yacht management companies to nurture eco-friendly practices onboard

Environmental Crew Guidelines preparing to launch: building support from yacht management companies to nurture eco-friendly practices onboard

A comprehensive package of crew best practices is being previewed at the Monaco Yacht Show to garner support from yacht management companies leading up to the anticipated launch of the guidelines in October.

Initiated together with MB92 Group and created by Danella Hopkins (formerly of S/Y Black Pearl), this package has been developed to enhance environmental sustainability onboard yachts and encourage crews to adopt more eco-friendly practices into their daily routines. Many industry experts and yacht crew members have contributed to address the unique challenges faced onboard in each department, ensuring a holistic overview. The guidelines will be offered as a free and open-source tool to support Water Revolution Foundation’s mission of fostering a more sustainable yachting community.

Reducing emissions onboard

Crews play a crucial role in maintaining the eco-friendly practices that reduce the environmental footprint of superyachts. “The work on the energy transition of superyachts has started. This transition will take time, with differentiated technical and technological solutions depending on the type of vessels and their usage profile. Nevertheless, there are immediate actions that crew can take on board to introduce more sustainable practices, which can significantly reduce emissions (by up to 30%), whether by optimising temperature settings, making slight adjustments to cruising speeds or employing effective resource management,” says MB92. 

Overview of guidelines

The guidelines are composed of 24 sections, distinguished between ‘Onboarding Guidelines,’ ‘General Guidelines,’ and ‘Departmental Guidelines.’ While the onboarding guidelines mainly focus on instilling the crew with an environmental mindset and promoting a commitment to eco-friendly operations, the general guidelines outline the basic principles and standards that apply to all crew members in their day-to-day tasks. The departmental guidelines were created to address the specific needs and practices of each department, taking into account their individual responsibilities. “I know first-hand the challenges that can come with operating in a more sustainable manner, and I hope these guidelines will not only support crew to be more eco-responsible onboard, but also serve as a reminder that even small actions play a significant role in contributing to the bigger picture,” shares Danella, writer and curator of the guidelines.

Implementing the guidelines onboard

Enforcing the guidelines onboard requires a coordinated effort. While the captain and heads of departments play pivotal roles in supporting and encouraging sustainable actions throughout the crew, designating a dedicated crew member to drive the onboard sustainability initiatives is crucial to ensure their implementation. As such, the job description for an “Eco-Sustainability Ambassador” (ESA) has been included within the guidelines to support any crew members with overseeing key action points and championing sustainability practices on the yacht.  Collaborating with Heads of Departments (HODs), the ESA customises guidelines, engages the crew, monitors progress, and reports achievements. This dedicated role will help to alleviate the HODs’ workload and streamline processes. 

Support for crew members onboard has also emerged from other influential industry players. Luxury Hospitality Management (LH) supports this initiative and aims to help crew implement these guidelines. Peter Vogel, Founder of LH, says: “We wholeheartedly endorse this initiative and understand that instigating behavioural change and reshaping mindset onboard can be challenging. Drawing upon our coaching and training expertise, we are committed to contributing our resources to help facilitate an era where crew eco-consciousness is at the forefront across all departments.”

This initiative aims to cultivate a stronger environmental ethos within yacht crews and become an integral part of their collective identity. 

Support needed from yacht management companies

“This project will equip crew with a comprehensive body of knowledge as well as readily accessible practical tools, representing an essential step towards a more sustainable and responsible future for superyacht operations,” shares MB92. 

The support of yacht management companies is crucial to ensure widespread adoption of the guidelines and enable a united, coordinated action – setting a minimum standard across the industry. Companies who get involved will be positioned as a leader, contributing to sector-wide change and guiding the way forward for a sustainable yachting future.

YETI 1.0 tool launched to revolutionise & reduce environmental impact of the superyacht industry

YETI 1.0 tool launched to revolutionise & reduce environmental impact of the superyacht industry

The first version of the highly-anticipated Yacht Environmental Transparency Index was launched at this year’s METSTRADE and shared with key members of the industry. The tool, which scores and compares yachts based on their environmental credentials, emphasises the operational efficiency of a yacht’s lifecycle and tackles ecological impact by benchmarking vessels against an average operational profile. With unrivalled experience and accumulated brain power, the YETI group came together to give valuable insights about the tool that enables the superyacht industry to make more informed decisions for new builds and refit projects. 

YETI 1.0 

The launch unveiled the details of YETI 1.0 and its focus on the most impactful part of a yacht’s lifecycle – its operational phase. By expressing the calculated emissions in EcoPoints and dividing such points with the yacht’s gross tonnage, YETI 1.0 determines a score that is relative and comparable within its class. Following regulations and engineering practices, the defined classes are <500, 500-3000GT, and >3000GT. Rather than looking at the entire spectrum, this comparison provides a targeted and informed approach to reduce EcoPoints within each size group, define the best in class, and learn from their optimisation. 

To use YETI 1.0, data concerning a vessel’s general parameters, speed-power, load determination, generators, battery bank, and heat distribution system must be submitted on the input sheet. When joining the fleet review, yachts are provided with an extensive feedback report that includes a YETI 1.0 score, explanation of how this score was determined, comparison to the rest of the assessed fleet within a given class, and suggestions for potential areas of improvement. 

The importance of YETI 1.0 for the yachting industry

By taking a yacht’s unique operational profile as a benchmark, YETI 1.0 provides scores comparing a single vessel to the rest of the fleet rather than applying the generic approach for commercial ships. YETI scores are calculated based on energy use for propulsion, including expected fuel, shore power consumption, and related emissions. Numerous studies have been conducted as part of the project, including the upstream impacts of fuels, engines and generators, and the average footprint of shore power in the most popular yacht marinas.

YETI 1.0 is paving the way toward a sustainable future in the yachting industry. This robust tool will guide members of the sector, from design and yacht management to new build and refit, in reaching a reduced ecological footprint through the development of better concept designs and concrete upgrades of existing yachts. The tool has also already received interest from marinas, insurance companies and banks who are eager to find a reliable reference for understanding yachts’ environmental credentials. 

Industry collaboration

Industry collaboration is essential for reducing the superyacht sector’s environmental impact, and YETI is a commendable example of the most renowned shipyards, naval architects, and research institutes joining forces to accelerate sustainable change in a transparent and reliable manner. The group, who represent an unrivalled fleet of superyachts with a shared motivation to understand and improve their ecological implications, have reached a new level of industry collaboration by setting competition aside to collaborate on this initiative. 

Companies that can support the group with expertise and data are encouraged to take part in this unique collaboration for the upcoming quest to develop YETI 2.0 and expand the tool’s scope beyond operational efficiency. In joining this project, participants will meet regularly to provide insights for YETI’s future progress. This presents an opportunity for captains, engineers, shipyards, naval architects and management companies to complement the group and be involved in the yachting sector’s journey toward sustainability.

How to get involved

You can now submit data for your yacht(s) in order to calculate its YETI score, which will come with a detailed feedback report providing a comparison with the rest of the fleet. “The groundwork has been done, it is now time for the industry and owners to utilise this reliable reference to know where a yacht stands and what opportunities there are to improve its environmental credentials,” said Robert van Tol, executive director of Water Revolution. 

Workshops will also be organised for members of the industry to attend a live YETI score calculation in order to better understand the required input, assessment process, and outcomes generated as a single score. This session will reveal how choices are rewarded and showcase how YETI is here to help instead of judge. YETI is far from a black box – the ‘T’ stands for transparency, as only then can we as an industry learn and show progress.

YETI moves into critical test phase and calls upon yachts for fleet review

YETI moves into critical test phase and calls upon yachts for fleet review

The first stage of Water Revolution Foundation’s Yacht Environmental Transparency Index (YETI) has been unveiled to the superyacht industry at the recent Superyacht Forum and METSTRADE. It came with a call to action to all relevant superyacht industry actors to get involved. Against the backdrop of COP26 and an increasingly global drive to tackle environmental issues, YETI 1.0 marks the first step of a highly anticipated tool to compare yachts based on their environmental credentials when in operation. The tool will enable client and project teams to make more informed decisions for newbuild projects as well as for upgrading existing yachts, and as such will help drive our industry as a whole towards a cleaner future.

Together towards sustainability

As the foundation celebrated its third anniversary during The Superyacht Forum in Amsterdam, and while speaking to an audience of key industry stakeholders alongside METSTRADE, Feadship CEO and founding chairman Henk de Vries, initiator and vice-chair Dr Vienna Eleuteri and naval architect Giedo Loeff from Feadship De Voogt all emphasised how important the issue is becoming for the future of the superyacht industry. It is among the most impactful tools Water Revolution Foundation is currently developing for the whole industry to use, to help improve the industry as a whole. 

How YETI started

The drive to create the index began in 2018, not long after the foundation was born as a not-for-profit organisation with the intent to drive sustainability across the superyacht industry through reducing its environmental impact and re-investing in ocean conservation. YETI stemmed from an approach Feadship De Voogt naval architect Bram Jongepier made to a group of international peers to develop a tool that enables the comparison of yachts and that can better showcase environmentally friendly designs.

Non-competitive collaboration

After three years of research and intense collaboration across a broad scope of shipyards, naval architects and renowned research institutes, the initial tool is now ready for testing. The collaborators for the initial phase were Abeking & Rasmussen, Benetti, Damen Yachting, De Voogt Studio, Delft University of Technology, Dykstra Naval Architects, Feadship, Fincantieri Yachts, Heesen, Lateral Naval Architects, Lürssen, Marin, MB92, Oceanco, Royal Huisman, Safe Harbor Marinas, Sanlorenzo, TNO Innovation for Life, and Vitruvius Yachts.

YETI 1.0 focuses on the most impactful part of the lifecycle – the operational side of superyachts. “The initial tool calculates the efficiency and the emissions of superyachts, and by being able to calculate these one can also identify the actual environmental impact,” said Giedo Loeff, naval architect at Feadship De Voogt. “A lot of companies answered our requests (for collaboration) and it was a lot of fun to talk about the various subjects. It’s not something we should want to compete over – it’s about knowledge, and really understanding how to reduce the impact we’re creating.”

Owners’ request

From the owners’ point of view, De Vries highlighted the change that Feadship has witnessed in the attitudes of yacht clients over the past five years, from where alternative fuels and power solutions were considered too risky by most clients to where sustainability is a key factor in the equation not only for their superyachts but also across their investments.

Dr Vienna Eleuteri, speaking from an industry point of view, added: “The real need coming out of COP26 in Glasgow is that it is the private sector that will make the difference and which will change the world in a very practical and efficient way. We are a really passionate group of people working for the same strategic goal.”

Data driven

A key part of the first phase has been collating operational information and studying the equivalent of close to 400 combined years of data collected via AIS from more than 100 superyachts. Among other things, the data showed that yachts are typically only underway at speed for 10 per cent of their time, with 56 per cent spent in port and 34 per cent spent at anchor. It is this sort of insight against which it is crucial to benchmark the yachts when assessing the impact from their cruise and hotel operations systems.

Fleet review

YETI wants to be inclusive for the many different types of yachts that are built and therefore it is critical to have all those represented in the fleet review. It should be noted that none gets judged yet, as first the calculator needs to be tested for its robustness by a representative fleet. While YETI 1.0 is a major first step, it is just the first step. It is in this regard that the whole industry now needs to take part. The more data gathered, the more confident YETI can move into the phase of scores and ultimately the different categories, also called labels.

Critical data needed

The data needed for a YETI score consists of energy inputs (fuel, shore power), system power demand (speed-power curve, electric hotel power and heat), and system power (propulsion motors, electric generators, heaters) – all combined with an operating profile. The data collection sheet will be shared upon request with those that wish to contribute to this important development. A feedback report on the yacht(s) is provided and a unique number allocated to follow its score along the further fine tuning of the YETI tool.

Henk de Vries, as chairman of the foundation and a self-proclaimed “worried shipbuilder”, addressed the required survival strategy for the eight years that remain of this decade. “If we do nothing,” he offered, “and we just build the boats that we currently build, then we will be history. There is a solution, and it’s not complicated.”

“The YETI score is something that we want to extend because the more data that we have, the better we can raise individual yachts,” said Loeff. “This is what could be in the future. But there needs to be more data, and there needs to be more participation. Now we are calling for participation.”

It is time to test the YETI 1.0 calculator through an extensive fleet review. The more yachts entered in the index, the better the calculator logic applies. So this is a call for shipyards, yacht management companies, and captains to submit as many yachts as possible, as well as for engine manufacturers to share the data emissions sheets of the engines installed in current and future yachts in the fleet.
