Wiszniewski Yachts


Dear Customers, Partners & Collaborators,

With humble beginnings dating back to 1989, Ślepsk was founded with a singular vision: to craft exceptional boats from laminate. Over the years, our dedication to excellence has driven us to become the premier European subcontractor for motorboats, trusted by many renowned American and European brands. Through unwavering commitment to quality, competitive pricing, and adaptability, we have cultivated enduring partnerships with our valued associates. Today, we stand proud, having evolved into a thriving business employing over 1,300 skilled individuals, producing approximately 3,000 motor yachts annually across a diverse portfolio of 90 distinctive models. As a family-driven enterprise, our aspiration to create our own marque has long been cherished—a dream rooted in over three decades of industry knowledge and innovation.

We now embark on an exciting new chapter with the introduction of Wiszniewski Yachts—a testament to our unwavering dedication to craftsmanship and innovation. With this venture, we endeavor to showcase our accumulated knowledge and aspirations.  Supported by a robust infrastructure encompassing departments dedicated to modelling, prototyping, engineering, laminating, assembly, and quality control we can be confident in our ability to deliver a product of unparalleled quality, refinement and reliability.

The W43 stands as the embodiment of this ethos—a flagship motorboat meticulously crafted with our collective expertise, knowledge, and passion woven into every detail.

After three and a half decades of dedicated effort and the wealth of knowledge accumulated through collaborative endeavors with our esteemed partners and dedicated workforce, we proudly unveil a vessel tailored for discerning enthusiasts—the W43. In a crowded nautical landscape, this craft embodies our signature Modern-Classic style—a harmonious fusion of timeless elegance and contemporary innovation.

The W43 epitomizes our ethos, seamlessly blending classic design elements, artisanal craftsmanship, and premium materials with cutting-edge technology and unwavering reliability. This blend encapsulates our unwavering commitment to crafting luxury motorboats that resonate deeply with their owners.

As the crown jewel of our 35-year legacy in the maritime domain, we christened our marque Wiszniewski Yachts, pinning our family name to the brand as a badge of honor is testament to our unwavering confidence in the quality of our products.

However, the W43 is not destined for mass production. Instead, we pledge our focus on precision, quality, and the pursuit of perfection throughout its construction. Our envisioned production volume of 20 to 30 units annually underscores our dedication to exclusivity and meticulous attention to detail.

Our offering caters to discerning individuals who value practicality, meticulous attention to detail, and an unwavering commitment to excellence. Those with an appreciation for refined style, unparalleled quality, and exceptional comfort will find a deep connection with a product designed to be cherished by its owner, their inner circle, and not merely for outward appearances. The W43 is poised to be a steadfast companion for years to come, promising timeless sophistication, exceptional comfort, and agile performance on the water.

In collaboration with the highly skilled team at J&J, a distinguished family-owned Slovenian design company, we embarked on the development journey for the W43 with a set of ambitious objectives. These guiding principles shaped our vision for the boat:

– Exceptional nautical performance
– A commitment to utilizing only the finest-quality and certified materials
– Deliberate design process: Each aspect meticulously crafted without haste, allowing time for refining details and integrating innovative ideas
– Distinctive identity: Our intention was not to rival established brands but to establish a unique style and elevate industry standards
– Emphasis on owner experience: The W43 was conceived to offer spaciousness, comfort, and unparalleled pleasure in its utilization

Lastly, our design ethos sought to ensure the W43’s enduring appeal—both upon initial acquisition and for years to come—by maintaining a timeless aesthetic that exudes contemporary elegance and freshness.

Mr Michał Paul Wiszniewski, Co-Owner & the entire Wiszniewski family and all the proud employees
