Sialia Yachts is proud to introduce the Sialia 45 Sport, a powerful electric yacht engineered for exceptional performance, luxury, and long-range eco-cruising.

Designed as the perfect entry point to electric yachting, the Sialia 45 Sport is a day cruiser that recognizes no compromise and can be tailored to the owner’s exact preferences. This innovative model was developed in response to extensive customer and market research. Construction on the first 45 Sport is set to commence in the summer of 2024.

Class-leading speed and range

The carbon fiber construction ensures class-leading speed and range. With her sleek hull designed by Petestep, the Sialia 45 guarantees a comfortable and dry journey. She cruises at 25 knots and reaches a top speed of up to 43 knots, offering a range of more than 70 nm in the pure electric version and a staggering 164 nm when fitted with a range extender.

Integrated solar panels reduce environmental impact by harnessing the sun’s energy to keep onboard systems running. Thanks to advanced charging technology, including the ability to charge with up to 350 kW of DC power, this unit is the fastest-charging electric yacht on the market while also compatible with AC shore power at any marina.


Complete customization to each owner’s needs

The 45ft yacht can be customized with three distinct trim levels: Active, Plus, and Premium, each providing an increasing level of opulence and material quality.

The Sialia 45 Sport can be configured according to each owner’s needs, with 2 layouts to choose from. The Sandbar offers a dynamic setting for adventure with friends, boasting sport seating for 6 and an exterior galley. The Lounge layout, on the other hand, is designed for relaxation and family enjoyment, providing ample sunbathing space with benches for 8, an enlarged lounger aft, and a full dining table for alfresco dining.

Three drivetrain options address different boating needs: Scout prioritizes coastal cruising, Performance exudes pure electric efficiency, and Range balances electric performance and long-distance navigation.

A luxurious yet sporty boat

“We recognized a demand in the market for a smaller model that offers an electric experience at an easier entry point,” explains Stanislav Szadkowski, Founder & CEO of Sialia Yachts.

He adds: “Opting for a 45-foot size allows for versatility and accessibility, fitting into most marinas and manageable for single operators. Our decision stemmed from thorough market research, aiming to create a luxurious yet sporty boat capable of traveling from Miami to the Bahamas​​ with a speed of 25 knots on electric power.”

“We’ve optimized design, materials, and drivetrains globally, ensuring uncompromised electric yachting. Introducing clear trim levels and a wide range of drivetrain options, supported by an online configurator, enhances transparency and ease for prospective buyers. Collaborations with naval architecture studio Petestep for hull design and Denis Popov Design signify our commitment to excellence in craftsmanship and innovation.”

Presenting the Versatile Sialia 59 Loft

Sialia Yachts, a leader in eco-luxury yachting, is proud to unveil the Sialia 59 Loft, a groundbreaking superyacht chase vessel that extends sustainability and onboard comfort to its mothership.

The Loft represents the ecosystem approach for a superyacht chase vessel. Not only does it replace multiple single-purpose tenders, but it enables any yacht to improve its operations and carbon footprint. This is achieved through its design, which elegantly combines three distinct functions into a single yacht. At night, the Loft truly excels. The various systems enable Sialia yachts to operate silently and emission-free, providing electric power overnight for peaceful stays at anchor.

Key highlights include:

From a design perspective, one of the most enchanting spaces aboard the yacht is “The Nest”. At the heart of the boat, it offers breathtaking panoramic views and immerses passengers in the Loft’s serene performance. The bow area smoothly blends with the main cockpit, unveiling a radiant lounge, a generously appointed dayhead, and a guest-serving bar while maintaining a seamless connection with the surrounding environment.

The Sialia 59 Loft’s aft deck transforms into a versatile beach club, serving as an ideal setting for watersports, leisurely relaxation, or provisioning trips for the crew.

On the technical front, the vessel features cutting-edge technology, showcasing Sialia’s proprietary battery solutions and a sophisticated Ship Management System (SMS). Complementing this is the powerful Ampros electric propulsion system, a staple in every Sialia unit. Owners gain the capability to monitor and command the yacht’s operations from any corner of the globe.

The boat can recharge its batteries using sustainable sources, and this power can be utilized to supply the mothership with energy. It is versatile in using a diverse range of sustainable fuels for both propulsion and generating power for the mothership. Thanks to the onboard hydrogen storage and fuel cell, it can silently produce power and generate significant amounts of H2O. Moreover, the onboard range extender is HVO diesel-ready, enabling the loft to complete long-distance passages at cruising speeds, recharge its batteries, and provide the mothership with electricity, all while maintaining low emissions.
