In 2010, a rigorous four-year sea trial was initiated in which they crossed the entire continent of Europe by river, sailed the dangerous Black Sea, the stormy Aegean as well as the vast Mediterranean Sea. Throughout the journey, the SOLARWAVE 46 did not only accommodate them with convenient amenities such as on-board water production, cooling and heating. It additionally accommodated eight guests on board with all the comfort needed for a total period of 120 weeks.
Furthermore, it was able to power the engines every day under various circumstances such as rain, cloudy sky, sun, snowfall, ice and even storms of force 9. It is important here to note that during this period of four years there were no maintenance or repair works required on the solar panels, the batteries or the electric engine. The generator, which has to be on board for safety reasons, was working for less than 50 hours during those 48 months – primarily to avoid becoming rusty. On the other hand, the electric motors were operating for more than 2000 hours for the same period of time with no maintenance needed.
After all those years of dedicated trials, this was the proof that the SILENT-Technology they had developed was the answer to the question they were asking ourselves themselves during the ocean expeditions. The solar-electric drivetrain was the most effective, efficient and reliable choice for nautical propulsion and self-sufficient sailing.
As a result they have now given over 150 lectures worldwide regarding the energy supplies and propulsion on yachts. Many of our learnings can be read up in their published book “Energy supply on yachts”.
Over the past years, SILENT-YACHTS has now received several awards honoring the research and development that was invested into this innovative technology.
