Bringing Light Into The Dark FAQs
What is the difference between a SILENT-YACHT and a conventionally powered yacht?2020-06-22T11:50:43+02:00

Conventional motor yachts are powered by diesel- or gas-engines. Additionally, they have a generator on board to supply all household appliances. Hence, depending on the size of the yacht, a total number of 2 or 3 diesel-engines are used 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-engine also ensures the energy-supply of the household appliances on board.

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 shower and drinking.

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 stores 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.

Are there different cabin configurations for each SILENT-YACHT model?2020-03-16T18:21:08+01:00

Every SILENT-YACHT can be configured in several different interior layout versions. For more details visit the dedicated site of each model.

Can SILENT-YACHTS be used for commercial use such as passenger ferries ?2020-03-16T18:20:12+01:00

Yes, commercial versions have been delivered already. As the requirements herefore can vary depending on the particular use case, we ask you to get in touch so we can customize the vessel for your specific needs.

How does the cooling and heating work ?2020-03-16T18:29:12+01:00

When the windows are closed, you can enjoy using the unique aeration-system which is installed in all the cabins, bathrooms and the saloon. It provides individually adjustable cool and fresh air at any time. The system can also can be combined with the air-conditioning. The roof overhang and the UV protection of the saloon windows also help to keep the inside of boat cool. In reverse mode, the heat-pump provides a warm and cosy interior all season long.

Which company builds the electric propulsion system?2020-03-04T17:00:02+01:00

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.

How many kW do the solar panels generate?2020-03-31T13:31:21+02:00

The exact number varies from model to model. On the SILENT 60, for example, the panels produce around 17kWp, which results in around 100kWh per day. This enables you to travel up to 125 miles every day, exclusively powered by the sun and run all the amenities like air conditioning, TV etc. as well as domestic appliances.

Do you provide enough energy for a water maker ?2020-03-04T17:04:16+01:00

Yes. The water makers we offer produce 100 to 450 liters per hour. They require around 1 KWh of energy per 300 liters of produced water. Thus, the consumption is only a fraction of the production of the solar panels. Therefore the energy needed for the water production can easily be supplied by the solar panels during the day or by the batteries during the night.

What about the CE Certification ?2020-03-16T18:17:05+01:00

All our yachts are CE category A* certified. This is the highest level of certification obtainable in Europe. SILENT-YACHTS are designed to circumnavigate the world. If you require further reinforcement of the hull e.g. against ice – we can customize towards your needs and build accordingly.

*CE A Certification means Category A: Ocean. This is the category 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.”

Can the generator charge depleted batteries and power the ship including all the appliances on board while the boat is underway?2020-03-04T17:06:06+01:00

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 emergency back up in case you travel long distances at high cruising speeds without sunlight as this could possibly deplete the battery reserves. Nevertheless, you can still go for 12 hours solely powered by the batteries even during the night at 6 knots speed.

What about the Kite Sail System ?2020-03-16T18:14:53+01:00

The Kite Sail Options is available for all our models. In comparison to a regular sail, the kite has several advantages:

  • No shade created on the panels

  • Much higher performance

  • Less maintenance required

  • Lower maintenance costs

It perfectly complements noiseless electric drive and is an effective addition to every SILENT-YACHT.
