22 October 2019


Silent Yachts, the Austrian company that has produced oceangoing solar-electric production catamarans, will present a new upgraded version of the Silent 55 at the Fort Lauderdale International Boat Show, from 30 October to 3 November.

The yacht uses silent electric propulsion for unlimited range with no noise, fumes or vibration, she is self-sufficient and virtually maintenance-free.

The new Silent 55 has a completely revised drive-train with significantly more battery power, two times more powerful e-motors, structural improvements and better noise reduction compared to the previous 2018 version.

“Our best-selling 16.7-metre innovative solar electric catamaran has been upgraded and become even better than previous models”, said Michael Köhler, Silent Yachts Founder and CEO. “We did these updates and changes because we always try to improve and to install the best and latest technology available to satisfy our clients. We have built one new Silent 55 already and have received three additional orders for this model, which confirms that we’re heading the right direction”.


Among other features, the new Silent 55 has a pair of 250 kW e-motors, 210 kWh battery capacity.

The shipyard has also enhanced noise reduction and made structural improvements to ensure that Silent’s emphasis on luxury and comfort continues throughout its product line.

With 30 high-efficiency solar panels rated for approximately 10 kilowatt-peak, the Silent 55 uses maximum power point tracking (MPPT) solar charge regulators and lithium batteries, which provide capacity for all-night cruising, while a 15-kVA inverter provides power for all household appliances. The systems require minimal maintenance and produce no fumes or noise. Because of that, the operational costs of the vessels are substantially lower compared to power yachts using more traditional propulsion systems.

“What this represents to the yachtsman, among other features, is the ability to cruise for many hours at normal speed and throughout the entire day and evening at reduced speed”, Michael Köhler comments. “Silent Yachts sets the standard for an entirely new dynamic in yachting: No fuel. No maintenance. Pure solar powered luxury.”

The Silent 55 that will attend the Fort Lauderdale Boat Show 2019 has a standard layout with large airy saloon on the main deck and four spacious cabins below decks, including a full beam master suite in the bow area.
