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.


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.


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…


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.


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 first and only oceangoing production yachts in the world that are fully solar sustainable and powered by solar energy. Pure solar-powered luxury. Based upon our extraordinary accomplishments to date, it is clear that SILENT-YACHTS represents the future of luxury yachting.

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 get 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.

Solar power meets luxury cruising

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.

SILENT-YACHTS was awarded with one of the Top Power Multihulls in the Industry for 2018.
Congratulations to Michael Koehler and team on their incredible achievement!
