SILENT 80 3-Deck: On board SILENT-YACHTS’ most spacious catamaran to date

The future of yachting is here, and it's silent, spacious and energy-saving. SILENT-YACHTS, leader in luxury solar-powered vessels, is set to launch its revolutionary solar-electric flagship – the SILENT 80 3-Deck. With an LOA of 24.3-meters, and the yard’s most voluminous catamaran to date, this cutting-edge yacht is slated to make its debut this year, bringing a new era of responsible yachting to the world's waters.

“What sets the 80 Series apart is that it combines incredibly high levels of luxury and sustainability like no yacht ever before,” says Michael Kohler, founder and CEO of SILENT-YACHTS. “With bespoke design by Marco Casali and 26 kWp produced by the state-of-the-art solar array, there is ample energy to enjoy all the luxurious amenities on board with zero emission.”

Open or closed: Taking customisation to the next level

With the SILENT 80 3-Deck, prospective owners can choose between the 80+-square-metre open or closed fly deck versions. Described as “the defining feature of the yacht” by Kohler, this allows the owner to tailor their onboard experience to their personal preferences.

The open version offers a sprawling 84-square-metre ocean sky lounge on the fly deck, for those who prefer being outdoors with a closer connection to the sea. For those who value privacy and panoramic views, the closed version provides two options. The first option boasts an owner's suite with a staggering 360-degree view and an expansive 41-square-metre private terrace aft. On the other hand, the lounge version is ideal for those who cherish shared experiences on board. It replaces the owner's suite with a generous 39-square-metre dining area, complete with a bar and galley, while maintaining the same aft terrace.

Maximised onboard space

When compared to other catamarans in this size bracket, the SILENT 80 3-Deck has a strategic approach to maximise onboard space without compromising comfort or aesthetics. The boat offers ample storage for water toys beneath the cockpit, enhancing the overall functionality and recreational opportunities of the vessel and making it a dream for watersports enthusiasts.

“In the aft portside hull, the staircase can be raised to reveal a fully enclosed tender garage with a lift and launching system,” Kohler adds. “It fits tenders with a maximum length of 5.2 metres and has a direct charging point to recharge electric SILENT tenders.”

Strategic design: Beauty meets efficiency

The SILENT 80 3-Deck's design is a seamless blend of aesthetics and functionality. The signature window strip running across each hull adds a touch of streamlined elegance to the yacht, a departure from the traditional bulky appearance of many catamarans. Esteemed interior and exterior designer Marco Casali deserves praise for his exceptional work in maximising solar panel coverage while maintaining an elegant and captivating shape. The result is a yacht that not only turns heads but also harnesses the power of the sun to propel you through the water with ease.

“The biggest challenge was to create a design that is visually appealing but also captures as much solar energy as possible,” Kohler explains. “As the solar array of course needs space, it still needs to integrate into the overall visual design language of a yacht in a beautiful manner.”

A solar-powered era of yachting

SILENT-YACHTS is at the forefront of ecological yachting, and the SILENT 80 3-Deck is a testament to its commitment to more sustainable solutions. With cruising speeds of 6-8 knots, the yacht's solar-powered energy system harnesses the sun's rays to generate silent, emission-free propulsion, offering unparalleled efficiency and a virtually maintenance-free experience.

Kohler highlights the importance of producing a yacht that is not only a pleasure to look at, but also very efficient. “All our yachts are required to be highly efficient in order to consume as little energy as possible while providing all the luxuries on board,” he says. “In order to achieve this favourable energy surplus, all onboard appliances need to be highly efficient, and the overall weight of the yacht must remain as low as possible to minimise the energy required for propulsion.”

The 25-year warranty on the solar panels underlines the shipyard's confidence in its green innovation and guarantees uninterrupted, eco-conscious cruising for years to come.

Meet the Silent 80 Tri-Deck

• By Yachting Staff
• Updated: December 2, 2019

Silent-Yachts has unveiled the design for its Silent 80 Tri-Deck, a solar-electric catamaran with a projected top speed of 16 knots.

This yacht is a variation on the builder’s existing 80-foot flagship, adding an air-conditioned lounge on the flybridge.

Owners have choices in the layout aboard the Silent 80 Tri-Deck. The yacht can be ordered with four to six staterooms, with an enclosed or open top deck, and with a customizable garage.

Because the yacht uses solar power, it has more garage space as opposed to engine-room space. The vessel can carry a nearly 15-foot tender, an amphibious car or any number of combinations of water toys.

What is the Silent 80 Tri-Deck’s cruising speed? 6 to 12 knots, with a top-end speed of 16 knots.

Headlining the news is the announcement that Austrian-owned Silent-Yachts has been restructured as Silent Group comprising several distinct divisions.

Silent-Yachts:  Offering fully electric, solar-powered catamarans from 60-120 feet for noiseless, zero-emission cruising. In addition, from now on a new sub-division will also build hybrid yachts that make use of both conventional propulsion and renewable solar energy. The first hybrid yacht is an 82-foot model to be built in partnership with VisionF Yachts.

Through the cooperation with VisionF, Silent-Yachts aims to support the Turkey based shipyard towards making their catamarans more sustainable. The extended hardtop flybridge of the so-called Silent VisionF 82 is fitted with a large solar array and a powerfull battery bank in order to provide sufficient energy to power all household and comfort appliances on board. As a result, guests will be able to enjoy the noiseless Silent experience without compromises when anchoring in a bay or docked in a marina. The alliance showcases the willingness of Silent-Yachts to assist other manufacturers to reduce their vessels dependency on fossil fuels by incorporating the proven solar technology of the Austrian pioneer. 

Silent-Tenders:  Offering a new range of electric Silent tenders, starting with a model of 4 metres in length. Further models will be announced during 2022. 

Silent-Management:  Offering the full spectrum of management services for Silent clients, from documentation, flag registration, certification and inspections to crew hiring, charter and yacht management, maintenance and servicing. 

Silent-Charter:  Offering Silent yachts for charter from the fleet base in Port Adriano, Mallorca and around the world.

Silent-Resorts:  Stunning zero-carbon, ultra-sustainable resorts with luxurious beachfront solar-powered residences. 

Silent-Shop:  A web-based outlet for electric water toys, smart electric gadgets as well as Silent merchandising products.

New production sites The Silent Group can draw on three production facilities around the world. Its shipyard on Italy’s Adriatic coast has five construction sheds with 22,000 m² of covered space and about the same area outside for building the Silent 60 series & and the Silent 80 series. 

The Swiss-owned and managed PMG Shipyard in Thailand builds the Silent 60 series. The yard has a 20,800-m² facility in Rayong with dedicated areas for each stage of the production process.

A new partnership with Coşkun Bayraktar in Turkey, founder of the Viaport Group has opened up more production opportunities. Bayraktar, who also owns VisionF Yachts in Istanbul, has invested considerable manpower in recent months to start up production of the Silent 60 series, Silent 80 series, SILENT 100 series as well as the new Silent VisionF 82. Boats of each series are already being built in Turkey. Including the Tuzla Viaport Marina, the copperation with VisionF Yachting provides access to more than 100,000 m² of production area.

Record sales in 2021 – the current order book 2021 was a record-breaking year for the brand with 21 yachts sold. There are 17 yachts currently in build at different stages of production, among them eight Silent 60 series, six Silent 80 series, two Silent VisionF 82 and the first Silent 120 (ex-Silent 100). 

Upcoming new launch The next unit to be launched will be a Silent 60 – Front Exit version. The solar electric catamaran will touch the water this month February 2022 and will head straight to the US where the owner is waiting. Another Silent 60 Front Exit will be launched by April and will be followed by more yachts later this year.

“I’m immensely proud of what Silent-Yacht has achieved over the years,” says Silent-Yachts founder and CEO Michael Köhler. “After beginning our research into solar yacht technologies in 2004, the company has evolved and expanded and last year’s sales show that we continue to grow. We are now a truly international Group with diverse interests requiring more extensive resources and production space. This enables us to collaborate with other shipyards such as VisionF to assist them in harnessing solar technology as a step towards a more sustainable future.”

Initiating its research into solar-powered maritime technology all the way back in 2004, Silent Yachts certainly knows a thing or two about electric and hybrid yachting. The yachting firm set out to deliver a variety of boats that utilize the sun as its primary energy source, aiming for a future zero-emissions maritime industry through the development of powerful concepts with sustainability as the main theme.

The firm's 2021 debuted  SILENT 60 yacht  is proof enough of the company's long history and prowess in its maritime endeavors. Taking after its 64-foot predecessor, the SILENT 60 is a solar electric catamaran that is largely considered a stepping stone in both tech and marketing ingenuity for what the firm has in store for the future.

The Silent Yacht 60 price sits at a $2.75 million premium, highlighting the broad strokes of ingenuity behind it in addition to the technological innovation that underpins its outer beauty. Steeped in solar panels, which cover almost the entirety of the boat's upper top portion, the SILENT 60 features two 250 kW electric motors, a 225 kWh battery bank with lithium-ion NMC cells, and a backup 150 kW Hyundai generator. It also has a state-of-the-art 17 kWp solar array and a rear deck that can be raised or lowered for swimming or dinghy docking.

The interior cabins, shown in full via  Electrek , showcase lavish woodwork, open-air environments, and a multitude of seating arrangements that ensure long trips at sea with a packed catamaran won't feel cramped. It has five beds across four cabins, all of which are as luxurious as the rest. The SILENT 60 is alone proof of the commitment that underpins Silent Yachts as a leading brand in sustainable maritime concepts.

Headed by brothers Michael and Heike Köhle, Silent Yachts first put to sea a concept boat designed to be fully self-sufficient via solar power in 2010. The company measured this potential over the course of five years, after which it began to deliver mass production yachts such as the 2016-launched SILENT 64, which the SILENT 60 takes after. In 2018, the SILENT 64 was awarded as the first-ever serial-production  solar-powered catamaran to cross the Atlantic , a 16-day-long trip that sawn the yacht traverse from Spain's Cartagena to Barbados.

Though certainly a testament to Silent Yachts' craft and ingenuity, the SILENT 60 is all but a mere stepping stone for the maritime brand in its future plans of building more stable, self-sufficient fleets of yachts across a wide variety of performance metrics. For starters, the company is setting sail on a potential all-electric dinghy, of which little information currently exists on potential specs and pricing. The Silent Yachts dinghy is intended to go in tandem with the firm's two larger catamarans, the SILENT 62 and SILENT 80.

Beyond the electric dinghy, Silent Yachts is likewise delivering a state-of-the-art hybrid offering in the form of its massive SILENT VisionF 82, built primarily for bridging both solar powers with battery banks for a new form of maritime boating experience. Coupled with its hybrid offering, the maritime firm is also doing some hush-hush internal R&D on bi-directional charging capabilities and even liquid-cooled batteries for newfound performance parameters on the open sea.

01. What is the price of a Silent yacht?

For more information about the prices of our Silent yacht models, please get in touch here: Contact

02. Can a Silent yacht cross the Atlantic?

All our yachts are CE-A certified, which means that they are suitable for ocean crossings. In 2018, the Silent 64 set a world record as the first serial production solar powered electric yacht to cross the Atlantic Ocean.

03. Are electrical yachts practical?

Yes. As the propulsion system of an electrical yacht has fewer components and is much smaller than a conventional drivetrain, there is an additional amount of space on board which can be used for a variety of purposes.

04. Are electric yachts quiet?

Silent yachts are quiet, as the electric motors are noiseless. However, some manufacturers make use gearboxes which could be relatively noisy.

05. Are electric yachts cheaper?

While the purchasing price of electric yachts is similar to the price of conventionally powered yachts, the ownership costs are far lower. This is a result of lower maintenance due to the lack of moving parts of a normal engine, less repairs bills and minimal to no expenses for fuel.

06. Can you buy a Silent yacht?

Yes, Silent Yachts offers full serial production solar powered electric yachts ranging from 60 to 120 feet.

07. Is there any electric yacht?

Silent Yachts are the first ocean-going electric production yachts in the world, which are powered by solar energy. Storing the energy of the sun in state of the art battery banks enables guests on board to be fully solar sustainable while having the possibility of unlimited range with zero emission.

08. Do you offer sustainable materials on board?

Yes, we do. You have a choice to choose between premium sustainable materials such as bamboo, flax fibre, basalt fibre and cork. They help shape a unique yachting experience while significantly reducing the overall footprint on the environment. For more details, please visit our dedicated sustainability chapter.

09. What is the meaning of the number in each of the Silent Yachts model names?

The number of each model (Silent 60, Silent 62, Silent 80, Silent 120) indicates the overall length of the yacht in feet.

10. Which boating licence do I need?

Silent yachts require the same motorboat license as any other boat of the same length in the same operational area. No specific license required.

11. What about the CE-A Certification? What does it mean for the buyer?

All boats available on the market are classified according to four different CE categories.

Category A – Ocean: This is the certification level with the toughest standards and covers vessels of 40’ and over which are designed to be self-sufficient for extended voyages. It is defined as the “category of boats considered suitable for seas with significant wave heights of up to 23 feet (7 meters) and winds of Beaufort force 9 (41-47 knots) or less, but excluding abnormal conditions such as hurricanes.”

Category B – Offshore: Boats operating offshore with winds to 40 knots and significant seas to 13 feet.

Category C – Inshore: Boats operating in coastal waters and large bays and lakes with winds to force 6, up to 27 knots, and significant seas 7 feet high.

Category D – Inland or sheltered coastal waters: boats in small lakes and rivers with winds to force 4 and significant wave heights to 18 inches.

All our yachts are CE-A certified, which is the highest level of certification obtainable in Europe. As a result, all Silent Yachts are true ocean cruisers designed to circumnavigate the world.

12. What are advanced sea trials?

The goal of advanced sea trials is to experience solar powered yachting first-hand and receive a personal introduction to understand the technology and its benefits in order to be able to make an informed purchase decision.

If you would like to come on board and do an advanced sea trial, please get in touch here: Contact

13. How much does it cost to operate a solar powered yacht?

The operational costs of a solar powered yacht are far lower in comparison to regular diesel-powered motor yachts. The main reason here fore is the fact that an electric motor only has one moving part in comparison to the hundreds of moving components of an internal combustion engine. Virtually no maintenance means virtually no maintenance costs. Secondly, refueling the conventional yacht with diesel makes up for a significant proportion of the operational costs. Recharging a Silent with the help of the sun however is free.

14. Are there different cabin configurations for each Silent yacht model?

Yes, every model in our range offers a variety of different cabin configurations to suit different needs. On our website you can find the standard cabin configuration of each model. If you would like to take a look at further cabin configurations, please get in touch with our team and they will provide you with the respective model brochures which showcase all options.

15. What are the main advantages of a solar powered Silent yacht?

In terms of the actual yachting experience, Silent yachts offer virtually unlimited range with zero emission. Furthermore, noiseless cruising makes sure you will have relaxing time on board.

The solar-electric drivetrain is not only the safest and most reliable marine propulsion system, in comparison to regular internal combustion engines there is virtually no maintenance required as well.

From an operations point of view, there are 8 years of warranty on the battery banks, 40 years on the solar panels and life-time warranty on the electric motors. Every Silent yacht is CE-A certified and therefore offers full trans-ocean crossing capabilities.

For more information, check out “Why Solar Power?” and “Why Silent Technology?”

16. What is the difference between a solar powered electric Silent yacht and a conventional powered yacht?

Conventional motor yachts are powered by diesel- or gas-engines. Additionally, they have one or even two generators on board to supply all household appliances. Hence, depending on the size of the yacht, a total number of 3 or 4 diesel engines are used to provide propulsion and feed the household devices with energy.

Sailing yachts need a diesel-engine too. Depending on the operational area as well as the wind- and weather-conditions, a diesel engine is required in addition to the sails for the propulsion of the boat. When anchoring in a quiet bay, the diesel generators ensure the energy-supply of the household appliances on board. In fact sailing vessels have a very similar engine setup as a motor yacht, just less powerful, therefore a sailing catamaran of 80 feed has always 2 diesel engines for the propulsion and 2 diesel generators. Compared to that an electric Silent yacht requires only one diesel generator, which reduces the required maintenance and the costs significantly.

As most yachts use gas for cooking, the open flame not only heats up the interior but also causes an imminent threat. Furthermore, on many yachts the consumables like water and energy are managed in a way that enforces the skipper to visit a marina every two or three days to charge the batteries and to buy water for showering and drinking. In contrast to that a Silent yacht is autonomous and self-sufficient. Therefore there is need to go to a marina on a regular basis, as a Silent produces the energy and the water it needs on its own with solar energy.

Lastly, a conventionally powered boat has a range of 300 to 500 nautical miles before needing to refill the diesel engine. The use of a combustion-engine is, of course, inevitably also combined with noise, exhausts and oily films in the water.

In comparison, a Silent yacht can cross oceans and stay in a bay for months by storing the energy generated through the solar panels in large capacity batteries. This electrical energy is used for propulsion and well as powering all household appliances on board. All this happens completely noiseless, without vibrations and pollution while also offering the possibility of having virtually unlimited range.

01. How big of an electric motor do I need for my solar powered yacht?

The smallest electric motors fitted to a Silent yacht are two 50 kW motors on the cruiser configuration of the Silent 60 series.

02. How do electric yachts get fresh water?

All Silent Yachts are equipped with a water maker, which processes sea water into fresh water.

03. Can you power a yacht with an electric motor?

All Silent Yachts are powered by electric motors. The instantly available torque ensures a smooth drive at any time. More information on our electric propulsion system can be found on our technology page .

04. How long does an electric yacht motor last?

As electric motors only have one moving part, they are very reliable in comparison to regular internal combustion engines, which have a larger number of moving parts. Therefore, at Silent Yachts we offer a lifetime warranty on all electric motors installed in our yachts.

05. What motors do Silent yachts use?

Silent yachts engineers design and configurate our proprietary in-house drivetrains. We only integrate components from leading producers in their respective industries. For more information about the solar-electric drivetrain , please visit “Why Silent Technology” .

06. Do electric yachts have generators?

All Silent yachts are equipped with back-up range extenders, which can recharge the battery banks whenever needed. More information can be found on our “Why Solar Power?” page.

07. How efficient are electric yachts?

As Silent yachts were created to be fully electric from the ground-up, they are highly efficient. Every aspect of our yachts, from the design of the hull to the interior and its appliances is designed to minimize energy consumption and maximize efficiency. This enables sustainable self-propulsion with virtually unlimited range. More information can be found here “Why Silent Technology?” .

08. Where do our yachts get electricity from?

The main source of energy of our yachts is the sun. In a typical holiday region during the typical holiday season on an average sunny day the solar panels produce enough energy to power the propulsion system as well as all household and navigational appliances on board for regular holiday use. To learn more about the solar technology powering our yachts, please visit our dedicated chapter here  “Why Solar Power?” .

09. How fast can a Silent yacht go?

The cruising speed is usually around 6 – 8 kn.

10. Why are there no wind generators?

During the testing phase of the Solarwave 46 Prototype, Michael & Heike gathered extensive experiences with the usage of wind generators as well. The energy they generate does not compensate for the energy loss they produce by throwing shade on the panels. When turning at high speeds, wind generators are also very noisy and do not create a Silent cruising experience. Depending on their placement, they are also quite dangerous, potentially creating serious safety hazards.

It is not surprising that not even sailors on sailing boats choose the windiest regions of this planet for their holiday. They prefer to stay in a calm a protected bay for swimming and even more to stay over-night. Calm and protected means no wind and therefore no energy coming from the wind generator. However, the shade created by the wind generators would affect the solar panels on every sunny day and as a result reduce the daily production.

11. Can the generator charge depleted batteries and power the ship including all the appliances on board while the boat is underway?

Yes. The generator can recharge the battery whenever necessary. However, it is generally not required to start the generator for the operation of any of the household appliances on board. It is also not required to start the generator for higher cruising speeds. It merely functions as a back-up in case you travel longer distances at high cruising speeds.

12. What about adding a regular sail or kite sail?

As regular sails would throw a lot of shade on the panels, which would lead to a significant decrease in energy, all our models are available with an optional kite sail system instead.

In comparison to a regular sail, the fully automatic towing kite has several advantages:

• No shade created on the panels • Up to 10x more towing power created per m2 • Less maintenance required • Lower maintenance costs

For all sailors who would love to make use of the wind as well, the kite sail system perfectly complements the trademark Silent Yachts solar electric drivetrain as an effective addition.

13. Is there a video showcasing the energy generation & consumption of your electric yachts in realistic scenarios?

Yes, you can check out our Silent 80 energy generation & consumption video here .

The storyline takes you along on a trip of two days in order to showcase a variety of realistic scenarios, based on the Silent 80 E-Power + version. It will show you exactly how different situations affect the production and overall energy management with the help of the solar panels, electric motors and lithium battery banks on board.

14. Which propulsion system do Silent yachts offer?

All our models are powered by our unique solar electric drivetrain. It consists of market leading solar panels, powerful electric motors, state-of-the-art lithium batteries and an efficient back-up generator. This system produces enough power in order to supply energy for propulsion as well as all onboard appliances. For more details, please visit “Why Solar Power?” .

15. How many kW do the solar panels generate?

The amount of power generated by the solar panels in total depends on the specific model. Here are the individual peak power figures and the daily production of each Silent yacht:

Silent 60 & Silent 62 3-Deck

• 16 kWp – about 100 kWh per day

Silent 80 & Silent 80 3-Deck

• 26 kWp – about 150 kWh per day
• 40 kWp – about 240 kWh per day

Important to note – the kWp does not tell you anything about the daily production. When the panels are mounted in an unfavourable angle to the sun – for instance on the sides of the hulls – they are shaded for most of the time of the day. Same applies if they are mounted on a roof with a mast and a boom placed on top of it. Or if they are configured in smaller areas of different size and different angle to the sun. In all these cases their production will be close to zero. It is not surprising that yachts of same size having panels on the hull sides harvest only a third of the energy which you get on a Silent.

The design of our solar roof and our arrangement of the panels are the secrets of the “Silent Autonomy”, which makes our Silent yachts so unique.

16. Which company builds the electric propulsion system?

The electric propulsion system is built in-house by using highest quality industrial grade products. Our specific configuration of every individual component makes the resulting system unique.

01. Can Silent Yachts be used for commercial use such as passenger ferries?

While commercial uses are not part of our regular model range, we have already customized our solar powered yachts for such situations in the past. The Silent 55 has been built as a passenger ferry. Therefore, we would kindly ask you to get in touch with us in order to evaluate potential commercial usage regarding your specific needs.
