\n\t\"Sialia<\/figure>\n

A relatively young boatbuilder called Sialia Yachts is assembling an impressive portfolio of all-electric luxury vessels<\/a> boasting some of the best power and range we\u2019ve seen in the marine industry. These Sialia yachts, like the all-electric 57 Deep Silence, offer a one mega-watt-hour (MWh) battery capacity and 400 kW motors capable of transporting a dozen passengers long distances.<\/p>\n

<\/p>\n

Sialia Yachts, founded in 2017, is a builder of custom sustainable yachts based in Warsaw, Poland. It has expanded its team to include minds from around Europe, including the Netherlands and Italy. According to the company website, its goal is to \u201cbreak barriers and set new standards in sustainable yachting.\u201d<\/p>\n

One look at its growing lineup of all-electric luxury vessels, and it\u2019s clear that the company is well on its way, delivering some of the more impressive technology and performance we\u2019ve seen in the blossoming marine electrifications segment. One of the stars of that lineup is the Sialia 57 Deep Silence<\/a> electric yacht, a 17.6-meter vessel that touts massive batteries, two powerful motors, and impressive cruising speeds.<\/p>\n

All while delivering an onboard experience that is plush and home-like. Check it out:<\/p>\n

Sialia Yachts offers seven different all-electric vessels<\/h2>\n

We highly recommend checking out Sialia\u2019s website to explore its entire lineup of electric yachts, including a 26.6-meter 80 Explorer<\/a> and 12-passenger 59 Weekender;<\/a> we will focus on the vessel seen above, the 57 Deep Silence\u2014the flagship model that inspired the boatbuilders\u2019 59 line of electric yachts available today.<\/p>\n

Per Sialia Yachts, this all-electric 12-passenger boat was designed with an \u201cunwavering commitment to sustainability, without compromising aesthetics or functionality.\u201d Sialia has achieved that goal in many ways, delivering to customers everything (comfort, luxury, performance, and zero-emissions) in a 19,000 kg carbon fiber package.<\/p>\n

The electric yacht boasts a 1,000 kWh battery pack complimented by a Vripack design hull that maximizes space for the all-electric drivetrain. The 57 Deep Silence is propelled by technology from AMPROS, which includes two 400 kW electric motors. That system also enables AC charging of up to 22 kW and DC fast charging of up to 150 kW. Those components combine for a sustainable and ultra-quiet drivetrain configuration that can deliver up to 390 kW of continuous power and push the electric yacht to speeds over 25 knots (~29 mph). Here are some charge rates and estimated ranges:<\/p>\n

Stalia named the yacht above Deep Silence for a reason. That electric yacht\u2019s powertrain and other vessels deliver 0 decibels of noise, allowing customers to enjoy the serene sounds of waves lapping and birds squawking.<\/p>\n

These electric Sialia Yachts vary in price based on a number of factors, including size, model, finish, powertrain, charging capabilities, and extras, but in the millions of euros range and go up from there. You can get a better look at the 57 Deep Silene from Sialia in its video below:<\/p>\n
