The Sound of Silence

Franc Jansen , Founder and Director of JMS Yacht Management was at Marina di Varazze to follow up on the outfitting of the luxurious electric catamaran: SILENT 55.

In 2019, this eco-friendly yacht won the “Best of Boats Award” in the category “Best for Travel” which entails that she is suitable for traveling long distance whilst living on board permanently. Her design and engineering enables her to cruise among inland waters and tough conditions at sea.

Another step forward in moving towards a sustainable yachting industry. Congratulations to Franz Böse, Lionel Joham, Jörg Schaaf, Michael Köhler and Malte Link from Silent-Yachts for implementing such a vision towards the right direction!

In November of 2019, the SILENT 55 won the “Best of Boats Award” in the category “Best for Travel”.
This specific category is defined as “suitable for long distance travels with all amenities to live on board permanently, adapted for both inland waters and the tough conditions at sea”.
Generally, she can easily be handled by two people, making the SILENT 55 ideal for families cruising with or without additional crew.

As the very first – fully solar powered – production yacht in the history of nautical travel, the SILENT 64 crossed the entire Atlantic Ocean in February 2018. This extraordinary achievement proved the outstanding durability and efficiency of the SILENT solar-electric drivetrain even during unfavourable and rough weather conditions.

SILENT-YACHTS are true world cruisers with the possibility of unlimited range, even when the sun is not shining. In case of longer periods of bad weather, the range extender automatically starts to recharge the lithium Batteries when they are low. Their capacity provides ample energy for propulsion as well as all household appliances including the air conditioning, ice-machine, water-maker or laptops (230 VAC / 110 VAC). There is no need to search for a marina in order to charge the batteries, get ice, refuel or to fill the water tanks. A SILENT-YACHT can virtually cruise for weeks without fuel or the need to start the generator.

High levels of luxury require permanently available energy. On a SILENT-YACHT, you can watch TV, enjoy a cold beer, have the air conditioning running and produce up to 2000 litres of drinking water per day without starting the generator. The air conditioning cools down the boat quickly and efficiently whenever needed. This, of course, is also true for heating during cold weather.

Efficiency and Weight
Underwater lines are optimised by Computational Fluid Dynamics (CFD) and towing-tank tests. The lightweight construction is a result of bionic design, the use of carbon fibres and high-quality resins. Interior furniture is made of stiff and lightweight composite plates with real wood-veneer. This reduces the weight significantly to about half the weight of a conventionally constructed and powered yacht. Each kg / pound saved is equivalent to less wave drag and friction and therefore less energy required to move the boat.

Overall, this leads to high levels of efficiency enabling fast and self-sustaining propulsion. Salon and cabins are wrapped in thermal insulation. Furthermore, all windows are shaded by either the roof and/or the hull, thus lowering the energy consumption needed to keep the interior at comfortable temperature levels.

All the electrical components are of high industrial quality and are being engineered / built in Europe and the USA. Motors, inverters and their cables are IP69 certified. This means that they even work when permanently submerged in highly pressurised water. In comparison to a conventional diesel powered propulsion system an electric motor is far more reliable as the only moving parts are the rotor and its two bearings. Fuel bases problems are an issue of the past as well. All wirings are tin-coated and all plugs feature a custom design which prevents humidity and water from entering. Additionally, all parts exposed to the marine environment are made of corrosion resistant materials.

Redundancy & Safety
All vital components are redundant to ensure double safety. The configuration of all components makes sure an overload is impossible, making the solar-electric drivetrain far safer than conventional propulsion systems. We are also proud to say that our catamarans were the first to be certified according to DIN EN ISO 16315 for the marine operations of electrically powered yachts.
