HISTORY

Michael & Heike Köhler are the solar-pioneers behind SILENT-YACHTS.

Upon completing his University studies, Michael practiced law for several years until the decision was made by himself & Heike to follow their life-long interest in the marine industry.

As both their hearts were longing for the open blue, they travelled the oceans for over 23 years on conventionally powered sailboats and motorboats. They both spent over 5.000 days on board of their yachts and sailed over 75.000 NM around the world. The experiences they gathered during more than two decades at sea lead them to the conclusion that there had to be a more efficient way to supply yachts with energy.

2005 | SEARCH & TESTINGS

For 3 continuous years they dedicated themselves to extensive pioneering research in the field of energy supply and consumptions on yachts. All the data they had collected during their investigation finally outlined a clear result. It strongly indicated that in holiday and vacations regions the sun is far more reliable than the wind, thus being the superior source of energy.

2008 | CONSTRUCTION OF SOLARWAVE 46

Based on the results of their research, Michael & Heike personally began with the construction of the Solarwave 46, the first fully solar powered catamaran in the world.

2009 | PROTOTYPE LAUNCH

In 2009, the Solarwave 46 was let into the water for the very first time. It was nothing less than the first ocean-going yacht which exclusively used solar energy not only for actual propulsion, but also to provide energy to all household appliances on board. This includes everything ranging from cooktops, stoves and the freezer to the air conditioning, washing-machine and water-maker.

2010 | BEGINNING OF 4-YEAR SEA TRIAL

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. The goal of this project was clear – prove that a solar electric drivetrain represents the most effective and reliable choice for nautical propulsion and self-sufficient sailing.

2014 | ACCOMODATION & COMFORT

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.

2014 | RELIABILITY & MAINTENANCE

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. During this period of four years there were absolutely 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.

2014 | COMPLETE SUCESS

After all those years of dedicated trials, this was the proof that the solarelectric drivetrain they had developed was the answer to the question they were asking ourselves themselves during the ocean expeditions. It is the most effective, efficient and reliable choice for nautical propulsion and self-sufficient sailing as well as being perfectly suitable for an independent life on board.

2016 | SILENT 64 PREMIERE

Marking a milestone in nautical history, the Solarwave 64 was the premier serial production solar powered luxury yacht in the world. As the first manifestation of a vision where luxury yachting works hand in hand with nature, she marked the dawn of a new e-ra.

2018 | SILENT 55 PREMIERE

The SILENT 55 delivered on the promise of solar powered yachting in a more compact package, making it available for wider audience.

2018 | WORLD RECORD SOLARWAVE 64

Meanwhile the Solarwave 64 re-wrote the pages of history for a second time. In February of 2018, she set off from Cartagena, Spain, to do something that had never been done before. After passing by Cap Verde, she continued on all the way to Barbados in the West Indies, making her the first serial production solar power yacht to have ever crossed the entire Atlantic Ocean. Between Spain and Barbados, she travelled around 5,500 NM to set up this world record.
