I would not even consider buying another boat!

Klaus Obermeyer, Emmy Award Winner

You are not just selling boats – you are the actual leading edge of a crucial and much overdue revolution to sustainable transport!

Klaus Obermeyer, Emmy Award Winner

Having designed and built the Island Pilot DSe 12m (diesel/solar-electric powered cruising cat), I understand and appreciate the fantastic accomplishment you have achieved with the SILENT-YACHT. Congratulations!

Reuben Trane, CEO of Island Pilot Shipyard

This one man [Elon Musk] single handedly forced an entire industry to go electric, as a matter of fact if they don’t all go electric now they will soon die. I would like to see the same thing happening for boating.

Klaus Obermeyer, Emmy Award Winner

Stay with this strategy – you will be the winner in the long run. In any case ecologically.

Adolf Kunkel, Germany

SILENT-YACHTS is an unique, wonderful project that illustrates the opportunities and perspectives of solar and energy-independent mobility. Full batteries instead of empty fuel tank at the end of a journey – with all the fun and comfort for free!

Gernot Apfelstedt from Boote magazine, Germany

With your SILENT-YACHTS you not only show a technical solution, but also demonstrate a way of life, which shows that it can go without pollutant emissions. 

Robert Schoblick, Publisher of e-motion.net

The people do not know how much money and trouble they could save themselves by reading your book – “Energy supply on yachts” (written by CEO Michael Köhler).

Jens Steinhaus, Germany

A sensational pioneering achievement in terms of electric mobility! That’s the future!

Peter Geisler, Germany

You are Heroes, Pioneers! The book of history, should have a golden page with YOU and your accomplishments in it!

George Kakissis, Greece

Nothing is beautified here – no “brochure advertising” as usual! It is rather understated. The reality is still a lot more beautiful!

Stefan Merker, Germany

We agree – that was the best holiday we have spent so far!

Dr. Matthias & Uschi König, Austria

It fills me with pride to spend my first environmentally conscious holiday on your boat. In a few years, it will be something normal to spend a holiday in nature, without burdening her.

Manfred Berger, Austria

The sun shines only faintly through the cloud cover, yet the SILENT-YACHT drives. The 60 m² solar panels produce so much energy that the catamaran can drive up the Rhine (German river) with 10 km/h, despite the countercurrent.

What they bring to life is important to people and hopefully helps to steer the energy policy view of things in the right direction. Thank you very much, also in the sense of my children.

ABAU - Austrian builder network, Austria

Thank you for the holiday with the SILENT-YACHT. With quiet electric motors we traveled from anchorage to anchorage. Traveling with the SILENT-YACHT is almost like being on a cruise ship.

Claus Ginthner und Heidi Possert, Austria

A great project, which you brought into the water – we are very impressed!
Many thanks for the informative trip – we hope that the solar ship will prevail in the long run!

Heike and Michael – two, who do not talk, but make! With the motto competence and passion you stand for innovation and progress.

Reiner „Calli“ Calmund, Germany

Aside from the obvious benefits of having a solar powered yacht, I was immediately attracted to the design of the SILENT 80. To me, it was a great synthesis of form and function.

Neil Murray, Co-founder of the NASDAQ listed company mimecast.com

The SILENT 55 is the most technically advanced project to date from Austria yacht designers SILENT-YACHTS!

Jonathan Bell from Wallpaper magazine, UK

One of the most innovative world premieres to take place during Yachting Festival Cannes 2018 was the debut of the SILENT 55, the first transatlantic solar-electric production catamaran.

With a white sheet of paper and an ambitious idea

Everything started with a piece of white paper, a pencil and a spirit for innovation. Today, when you cross the oceans with a SILENT yacht, you are powered by pure and clean solar energy without giving up any of the exhilaration, comfort and luxury that you get from a conventional yacht.


The power of the sun is at your command.

SILENT-YACHTS was founded on the dream of eliminating the major downfalls of yachting as well as the disastrous effects on your wallet and the environment without sacrificing the slightest bit of luxury. The future of luxury yachting is individualistic, noiseless, self-sufficient and honouring nature and environment.


A true world cruiser with unlimited range.

On a SILENT Yacht water and energy production is done on board, large freezer capacity and large storage spaces facilitate independence, infinite range and self-sufficiency for weeks. This means no fuel-stops in crowded marinas but diving in solitary bays and enjoying the sunset with a glass of wine…


Did you listen to the pure sound of water today?

Electric-motors, solar panels and batteries work without any noise. You only hear the SILENT yacht gliding through the water. Your SILENT yacht is as silent (!) as a canoe and by far quieter than a sailboat which needs a lot of wind to sail with six to eight knots.


The only footprints you leave are those in the sand.

Imagine starting every morning with an inspiring sunrise, and ending daylight with a breathtaking sunset! Watch, smell, feel nature and be aware that you take responsibility for the environment. Ease out, relax and enjoy the most beautiful and interesting places to cruise on Earth.

SILENT-YACHTS presents the first and only oceangoing production yachts in the world that are fully solar sustainable and powered by solar energy. Pure solar-powered luxury.

Conventional motor-yachts are powered by diesel- or gas-engines. Additionally they have a Generator on board to supply all household appliances. Depending on the size of the yacht, two or three diesel-engines are working for propulsion and household. On sailing-yachts, depending on the operational area and the wind- and weather conditions, additionally to the sails a diesel-engine is needed for the propulsion of the boat. When anchored in a quiet bay, the noisy diesel-engine is operated to provide the energy needed on the boat.

Most yachts are using gas for cooking, the open flame heats up the interior of the yacht and cause an imminent threat. 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 shower and drinking. Larger Yachts operate water-makers, air-conditioning and generators. They do not need to got to a marina, but the use of a combustion-engine is inevitably combined with noise, exhausts and vibrations as well as oily films in the water: Not the nicest experience in an otherwise quiet bay

A conventionally powered boat with diesel engine propulsion has a range of 300 to 500 nautical miles. With a sail the range can be extended, but only when the wind is coming from the right direction and in matching force.

SILENT-YACHTS offers you a completely new experience of nature and watersports, without noise or exhausts.

We have developed a modular and scalable system that reduces the operation-hours of diesel-engines and thus the fuel-consumption to close to zero. The SILENT System is simpler, needs less maintenance and costs less than any conventional fuel-depending propulsion and energy-supply. At the same time it grants more luxury, comfort, independence, reliability and safety.

Do you want to have a “propane-free” kitchen and more comfort while on anchor? Do you want to go for solar-electric propulsion? Are you the owner of a Megayacht who wants to sleep without the noise and the vibrations of permanently running generators:

We have the solution for you. A new class of yachting is on the rise.
