What Sialia Yachts does
Sialia Yachts, operating under parent company Silent Straits Ltd. (incorporated in Cyprus, headquartered in Warsaw, Poland), designs and manufactures bespoke electric luxury yachts. Founded in 2017 by Stanislaw Szadkowski and Tomasz Gackoski, the company produces carbon fiber and aluminum vessels across multiple model lines: the entry-level Sialia 45 Sport, the pioneering 57 Deep Silence, the versatile 59 series (Weekender, Runabout, Sport, Loft), the flagship 80 Explorer, and the Volantis aluminum sub-brand. The core technology is the proprietary AMPROS electric drivetrain — a scalable propulsion, battery, and energy management system (up to 6 MW and 1 MWh capacity) with active battery cooling, bio-diesel range extenders, and optional hydrogen fuel cells, all controlled through the proprietary Ship Management System (SMS).
The company generates revenue primarily through one-time bespoke yacht sales to high-net-worth individuals, with supplementary recurring revenue from extended warranty programs (up to 10 years) and hardware sales of customized charging solutions for private and commercial docks. Distribution is factory-direct from Poland, supplemented by a representative office in Barcelona, with sales driven by presence at premium boat shows (Monaco Yacht Show Sustainability Hub, Cannes Yachting Festival, Palma International Boat Show). The customer base is concentrated among luxury yacht enthusiasts, superyacht fleet operators seeking electric chase vessels, and emerging segments in commercial marine energy (via the Nest floating charging hub). The company has expanded its product surface in 2024–2025 from a single model to a full portfolio across multiple price tiers and use cases, signaling a transition from niche builder to multi-line marine electric vehicle and energy infrastructure provider.
