Warranties

Reliability

Due to the lack of “moving Parts” associated with this technology, our yachts are considerably more reliable, and much less expensive to operate, with a considerable reduction in maintenance. All Silent Yachts are also built to the highest possible safety standards, achieving CE-A (ocean) certification.

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’re rated to work when permanently submerged in highly pressurized 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.

All wiring is 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.

As our yachts are consistently powered by the batteries, going “dead ship” when switching from shore power to generators is a thing of the past, therefore eliminating the frequent power cycling to electrical equipment and electronics. This greatly increases the lifespan of equipment on board, and reduces breakdowns, failures and service cycles.

Redundancy and Safety

All vital components are redundant to ensure double safety. The configuration of all components makes sure an overload is impossible, deeming 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.

In the unlikely event of a failure of the battery system, the generator can directly power the drive motors, as a “get home safe” system.

Efficiency and Weight

Underwater lines are optimized by Computational Fluid Dynamics (CFD) and towing-tank tests. The lightweight construction is a result of bionic design, the use of carbon fibers 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/Lb saved is equivalent to less wave drag and friction and therefore less energy required to move the vessel through the water. 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 a comfortable temperature.

Solar Panels

The photovoltaic modules recharge the batteries with a maximum output of 17 kWp and are designed to be the main power source of our yachts. We use some of the most efficient, advanced and highest quality modules currently available. Their arrangement, the positioning and the regulation of charge are some of the main secrets and reasons why our yachts are able to harvest that much energy from the sun - sufficient to power all household appliances, all devices that you need for your comfort and even the propulsion system.

Batteries

High safety and flexible system configurations were the design principles during the development of the RS series Lithium-Ion battery. A modular and compact design makes, and adding a redundant BMS create a unique cell-to-cell propagation protection. Thus taking safety to the next level. The liquid thermal management keeps the battery cells at optimal operating temperature to extend cycle life and to improve the peak power performance. These features make this battery ideal for our yachts.

Protecting, monitoring and controlling a battery pack is very important to create a safe, reliable and easy-to-use system. The MG Master LV or HV is the safety and control unit of the batteries. It protects the connected battery modules against over-charging, over-discharging, over-temperature, under-temperature and controls the balancing of the battery cells. Besides a safety function, the MG Master LV or HV monitors and tracks other important parameters to give insight in the battery status and energy consumption. The battery system CAN-bus protocol communicates with other equipment and multi functional display and web interface.
