Technology - Sialia Yachts

Drivetrain Options

A range of battery capacities and range extender options are available. With the implementation of a Ship Management System (SMS) failures caused by misuse or abuse of the system are eliminated.

Sialia’s are fitted with chargers to accept a range of power connections to facilitate charging in any situation. Sialia works with its customers to determine the right charging infrastructure for their application.

Pure electric

Our Sialia 1000 flagship capacity facilitates the purest electric experience while underway and at anchor. The Sialia 700 battery balances similar performance with a lower weight and cost.

Electric + Range Extender

Sialia yachts can be configured with variable rpm, bio-diesel certified, range extenders that offer cruising at 16 knots to a compact unit for increased autonomy and speeds up to 10 knots. Depending on local infrastructure, hydrogen fuel cells are an option for ultimate sustainable cruising.

Eco-system

True sustainability requires an ecosystem perspective. When designing a Sialia yacht we optimize the lifecycle and the performance requirements of our yachts. This goes further than just applying sustainable materials, but also making sure our yachts are not only ready for the energy transition, but can play a key role in making yachting more sustainable.

Batteries

From a use-case perspective marine operations are very different then automotive applications. Through its experience Sialia yachts has developed batteries that combine the most efficient battery configurations to create batteries that no only have large capacity, but can also sustain extensive periods of high discharging.

Range extenders

Depending on your requirements it may be desired to fit a range extender, Sialia yachts can be configured with a wide range of range extenders. From a bio-diesel range extender that can support sustained cruising at 16 knots to hydrogen fuel cells to keep the topped of for extender periods at anchor.

Ship management system

Sialia’s proprietary developed SMS (Ship Management System) and user interface follow the latest trends in user oriented design to deliver an effortless and intuitive handling of the vessel. All systems are optimized to minimize energy use and prevent breakdowns and allow owners to monitor or control the yacht from anywhere in the world.

How does Sialia Yachts approach sustainability in design and construction? add

At Sialia, sustainability isn’t an afterthought — it’s the foundation. All our yachts are fully electric, delivering a significant reduction in emissions during operation. But we go further. From the very first design sketch, we consider the entire lifecycle of every yacht. That means selecting high-performance, low-impact materials that meet our exacting standards for quality and sustainability. You’ll see this commitment in every detail — from the carefully curated interiors to our lightweight, responsibly sourced.

How does Sialia ensure safety and reliability in its electric yachts? add

Beyond meeting all conventional maritime safety standards and CE & ABYC certification requirements, every Sialia yacht is equipped with an advanced Ship Management System. This intelligent system integrates a network of redundant safeguards designed specifically to protect the electric drivetrain from misuse or failure. Continuously monitoring performance, it keeps the user informed while actively safeguarding the vessel — ensuring you’re never left without control or power, no matter the conditions.

How are the batteries and drivetrain protected on Sialia yachts? add

Sialia yachts use industrial-grade batteries paired with active cooling and our intelligent Ship Management System. This ensures the drivetrain and battery system are continuously protected from misuse or overheating. Every element works together to safeguard performance and extend longevity — so you can focus on the journey, not the systems behind it.

Where is Sialia Yachts based and who makes up the team? add

Sialia Yachts is based in Poland, where European craftsmanship meets cutting-edge marine technology. Our team is proudly international, with experts from Poland, Belgium, the Netherlands, Italy, and the USA. This global perspective and engineering excellence power every luxury electric yacht we build.

Where are the boats produced? add

We produce in Poland.

What is the process of realizing a Sialia yacht? add

Realizing a Sialia is a refined and personalized journey to your dream electric yacht. We start with an intake to understand your cruising style, preferences, and charging options. Based on this, we prepare an initial design and pricing using our dedicated Price List.

You can discuss any custom designs, after which we execute the Yacht Manufacturing Contract to secure your build slot.

Our team then develops the yacht in detail — from engineering to interiors, materials, and colors. You’ll receive regular updates at key milestones.

Once complete, your custom Sialia yacht is delivered — fully equipped and ready to cruise

What energy and charging solutions are available with Sialia Yachts? add

Sialia Yachts are powered by advanced electric drivetrains supported by Ampros — our in-house propulsion, energy management and battery system. This technology enables multiple smart energy solutions:

Home integration: Your yacht can be charged directly from your beach house or home energy system. It can also return stored energy to your property during periods of high demand.

Fast charging stations: We offer customized fast-charging solutions for private docks or commercial use, ensuring quick and efficient recharging between trips.Sialia 59 Loft: This model is designed for flexible, sustainable operation. It enables silent, zero-emission anchoring and can supply energy to a mothership — ideal for eco-conscious cruising or support fleet roles. With Ampros and Sialia combined, your yacht becomes more than a vessel — it's part of a smart, sustainable energy ecosystem. Contact us to explore solutions tailored to your location and needs.

Can I equip my Sialia yacht with a hydrogen range extender? add

Yes — in line with our commitment to sustainable innovation, Sialia Yachts offers the option of a hydrogen range extender for select models. This mature and proven technology is already in use in advanced marine applications and can significantly extend your vessel’s operational range while maintaining zero-emission performance. Availability depends on your local infrastructure and cruising profile, and our team will work closely with you to assess feasibility. If you're looking to combine the elegance of electric yachting with the extended autonomy of hydrogen power, contact us to explore this solution tailored to your needs.

What maintenance does the AMPROS electric drivetrain require? add

Our AMPROS electric drivetrain is designed for reliability and minimal maintenance — a major advantage over traditional internal combustion engines. The first major service is only required after 10 years or 10,000 operating hours, involving a simple grease replacement for the motor bearings. Routine upkeep is limited to an annual check of the liquid cooling system to ensure optimal thermal performance. All other onboard systems are high-quality marine-grade components from trusted global brands and follow their own standard maintenance schedules. With AMPROS, you benefit from a low-maintenance, high-performance solution built for long-term peace of mind.
