2020 Silent Yachts Silent 60

Miami, Florida


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 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.


Please contact us today to discuss converting your diesel inboard catamaran to solar power at any location in the world. Solar conversions for house only or house and one engine or house and both engines available.

Cruiser Version

2×30 kW

Noiseless cruising without any emissions, with unlimited range. The sound of the waves is like music in your ears and there is nothing disturbing this feeling.

Significantly lower purchasing price and maintenance costs, nearly no maintenance work, operational costs close to nothing and highest level of security and reliability.

E-Power Version

2×250 kW

The “E-Power” version comes with stronger dual e-motors than the “Cruiser” and more powerful batteries banks. This allows a higher top speed as well as a higher cruising speed compared to the “Cruiser version”.

Hybrid Power Version
2×220 HP + 2×14 kW

With the “Hybrid Power” version, a hybrid of powerful diesel engines together with the electric motors achieve top speeds of 20+ knots.

Kite Version

The Kite version features a towing kite with full automatic control. The SILENT yachts as well as the Kite System are adapted to complement each other perfectly, offering noiseless cruising and unlimited range but without any emissions. Conventional sails require a lot of space on the deck as well as maintenance and create shade on the solar panels. The Kite flies in altitudes of between 100 and 150m where the winds are much stronger, so the kite generates up to 20 times more power per square meter.

The Secret Behind the Silent Yachts

What is the difference between a SILENT YACHT and a conventionally powered yacht? The special configuration of the components guarantees that the solar-panels generate more power on an average day than the total consumption for propulsion at cruising speed. This includes all household appliances – on an average holiday trip to a typical holiday destination. SILENT YACHT technology ensures that long passages on solar power are a day-to-day experience.

The exceptional energy efficiency of SILENT YACHTS is achieved by:


  • Bionic design

  • Towing-tank-optimized hull-shape

  • Wind- and wave-drag optimized design

  • CNC-milling of the molds

  • Construction in carbon-composite with resin-infusion

  • Light-weight and structurally strong layout

  • Fully insulated hulls

  • Durability and long- term maintenance of value by using high quality resins


Special Features include:

  • Ergonomic design guarantees comfortable life on board

  • Innovative propulsions and technical devices grant luxury and performance at minimal cost of maintenance

  • Modular construction and efficient design facilitate creative ideas at a reasonable price

  • Luxury equipment such as dinghy garage or liftable stern-platform, as well as induction cooktop, large 230V inverter and lithium consumer-battery

  • Autonomy – unlimited range without the need to refuel, recharge or fill up the water-tanks.

  • With the water-maker you can produce up to 3 tons of fine potable water every day. In combination with the huge cooling and freezing-capacity a SILENT yacht is your personal island, offering everything you need for an independent and autonomous life for extended periods of time. There is no propane on board. All household appliances work with 220/110 Volt, just like at home.


For those rare occasions of protracted foul weather, or high cruising speed over a longer period of time, all yachts of the “Cruiser” and “Sailor” series have a diesel generator which serves as a range extender. Once the sun reappears, the batteries receive a free refill. You save substantial amounts of fuel and money, protect the environment and enjoy comfortable, relaxed sailing over long periods of time, independent of weather or external resources.

Energy Generation and Consumption

A SILENT yacht can cruise up to 100 miles a day without fuel, permanently and for weeks featuring virtually unlimited range. SILENT solar power systems feed the electric propulsion of the catamarans (short term speed up to 20kn) and all household energy needs. What is the technology behind this?


Light-weight Lithium-Batteries provide ample energy for the propulsion as well as for all household appliances, e.g. for television, air-conditioning, ice-machine, water-maker, laptop etc. There are various types of lithium-batteries on the market. The brand we are using is among the most expensive ones. But they are best regarding liability, safety, performance, weight and life-span.

Reliability: The solar-panels are integrated in the roof, so there is no wind-load on them. The batteries and electric-motors are inside the boat in a dry and safe place. All wiring is tin-covered and all plugs are specially designed for marine operation. All parts exposed to the marine environment are made of corrosion-resistant materials. All components are virtually free of maintenance. So the operating-costs are much lower than on a comparable conventionally powered catamaran.

Luxury: depends on energy, always available, like at home with 220/110 Volt electricity. All kinds of electric consumers can be connected. Without operating a generator you can watch football on TV, have a cold beer, run air-conditioning and enjoy bright interior and exterior lighting – for as long as needed. Production of up to 3.000 litres of drinking water per day grants you a kind of comfort you would not have considered possible up to now. This is “SILENT” and emission-free luxury.

Maintenance: The diesel range-extender requires much less attention than 2 large diesel-engines or sails in a conventionally powered catamaran. Solarpanels have a guaranteed life-span of more than 25 years. After that time it will be quite cheap to replace them. The Lithium batteries have a guaranteed lifespan of 8 years. The electric motors are completely free of maintenance. So the maintenance-costs are much lower than on a comparable conventionally powered catamaran.

Performance and Efficiency: Due to their exceptionally low weight, the streamlined shape and the towing-tank optimised underwater-lines, SILENT Yachts have less wave drag and friction than other sailing- or motor-yachts. This unique efficiency makes them fast and enables self-sufficient propulsion.aRange is unlimited with solar powered electric propulsion = more than Transocean-range.

Range-Extender: A diesel generator provides ample energy in case of longer periods of bad weather. It starts automatically when the batteries are low and ensures properly filled batteries to supply the propulsion as well as all household appliances.

Range is unlimited with solar powered electric propulsion = more than Transocean-range.

Redundancy and Safety: All vital components are redundant to ensure double safety. Due to the configuration of the particular components an overload-situation is impossible. The SILENT System is by far safer than any other propulsion like sails or diesel-engines.

Recuperation: The “Sailor” and the “Sky Sails” version of the SILENT yachts can recharge the batteries while sailing. When the propellers are turned by the water-flow, the electric motors produce energy to charge the batteries.

Solarpanels: Produce the energy for the propulsion as well as for the luxury household, including air-conditioning, cooking, refrigerating etc. The energy is stored in state-of-the-art Lithium-Batteries.

Speed: Depending on the chosen motor configuration, a SILENT yacht offers a cruising-speed of 6-8 knots and a top speed of up to 20 knots.

Weight: Each kilogram less means less energy required to move the boat. A Silent-Yacht has only half the weight compared to a conventionally constructed and powered yacht. Thus she is two times more efficient – and much faster. This enourmous weight reduction is due to weight-optimising design, expensive materials (Carbon, Aramid, Epoxy-resin) and elaborate construction techniques.
