SAY Carbon Yachts is among the very few shipyards that have truly leveraged the full potential of carbon fiber yachts, and it has recently introduced its new flagship model, the SAY 52, marking a significant step forward in high-performance yacht design.
Over the past decade, carbon fiber has become a strategic material in high-performance yachts, gradually moving from aerospace and motorsport applications to the marine world. Its unique mix of exceptional strength, light weight and design freedom has reshaped the way modern yachts are conceived and built.
For naval architects and engineers, carbon fiber represents a turning point. On one side, it enables higher speeds and enhanced fuel efficiency; on the other, it allows for sharper, more daring design solutions without sacrificing safety or structural robustness. Today, this advanced composite is widely adopted in elite sailing classes such as IMOCA, TP52 and America’s Cup yachts, as well as in fast motor yachts and innovative electric and foiling boats, where weight reduction is essential.
A yacht fully built in carbon fiber
SAY Carbon Yachts has made carbon fiber the core of its identity. Expanding an established range that already includes the SAY 29 and SAY 42, the shipyard officially presented the SAY 52 during the Palma International Boat Show. Entirely constructed in carbon fiber and manufactured in Germany on Lake Constance, the SAY 52 embodies the brand’s DNA: bold styling combined with advanced lightweight yacht construction. During the event in Mallorca, the first unit was showcased by CTO Karl Wagner and Head of Sales Carlo Vassallo.
The new flagship model
Defined by streamlined lines, ultra-light displacement and a distinctly sporty character, the SAY 52 targets owners seeking a yacht with genuine supercar appeal. With an overall length of 15.95 metres, it accommodates up to 12 guests. Remarkably, its dry weight is just 7.5 tonnes—around one third of a comparable fiberglass yacht.
The reduced mass, together with a wave-piercing bow, contributes to improved fuel efficiency and excellent handling, even at high speeds. This is particularly evident in the yacht’s ability to perform dramatic 45-degree banked turns while maintaining stability and full control.
Propulsion options include two low-emission Volvo Penta V8 engines delivering a combined 860 hp, or Volvo Penta D6 units with a total output of 880 hp, allowing the yacht to reach a top speed of 45 knots. An optional hybrid-electric configuration is also available, enabling silent manoeuvring in marinas and protected areas. Thanks to its lightweight structure and efficient engines, the SAY 52 can consume up to 50% less fuel than comparable models, reinforcing its credentials as a sustainable yacht design.
The complexity of carbon fiber manufacturing
“Opting for carbon fiber means embracing a more complex construction process, but one that delivers exceptional results,” explains Karl Wagner, Chief Technology Officer at SAY Carbon Yachts. The unidirectional nature of carbon fibers offers high flexibility when defining the structural layout of a yacht.
Wagner is widely recognised as one of Europe’s leading specialists in carbon composites, having previously founded Carbo Tech Composites GmbH, a company active in the automotive and Formula 1 sectors. To ensure structural integrity under high-speed loads, SAY commissioned UK-based composite engineering experts to perform Finite Element Analysis (FEA) on the entire structure.
A strictly controlled production process
Carbon construction leaves little margin for error. Factors such as fibre orientation, lamination sequence and curing conditions are critical. For this reason, SAY Carbon Yachts introduced a multi-layer quality control system throughout production.
Every manufacturing step is documented and double-checked by both the operator and a supervisor. Each component is weighed, while Differential Scanning Calorimetry tests verify correct curing of the carbon fiber. This attention to detail ensures consistent quality across all parts. For instance, the T-top arch is built using three carbon layers oriented in different directions, enabling it to withstand acceleration forces of up to 6G.
Technical innovation and refined aesthetics
The SAY 52 features a patented Petestep hull, distinguished by V-shaped, curved spray rails rather than traditional parallel ones. These rails channel water beneath the hull, generating a pressurised cushion that improves efficiency, reduces noise and minimises slamming. The hull has been optimised for cruising speeds of 20, 30 and 40 knots, delivering consistent performance across different operating profiles.
Designed in collaboration with Genesis Design, the yacht showcases refined aesthetic solutions throughout. Soft, flowing forms characterise the T-top, glazing and interior spaces, giving the SAY 52 a distinctive and cohesive visual identity.
On deck, the layout is focused on comfort and social interaction, with a contemporary galley, spacious lounge areas and generous sunbathing zones. Below deck, well-proportioned cabins provide a welcoming private environment. A dedicated stern-access Seabob garage ensures water toys are always close at hand.
A new phase for SAY Carbon Yachts
Following a challenging period, SAY Carbon Yachts GmbH has recently relaunched under new ownership, securing long-term stability and renewed strategic direction. The company has confirmed its commitment to delivering premium-quality yachts and reliable customer support, while continuing to operate from its German headquarters with an experienced core team. This relaunch marks a new chapter in strengthening the brand’s position as a benchmark in carbon fiber yacht manufacturing.
