45 Wiszniewski 2025 Boat for Sale

45' Wiszniewski 2025

W43 by W Yachts (Wiszniewski Yachts) — the modern‑classic 45‑footer that’s built, not churned.

Born from a father‑and‑son vision—Josef and Michael Wiszniewski—the W43 is the first self‑branded yacht from one of Europe’s largest OEM boatbuilders. For 35+ years their yard has quietly built thousands of boats for the world’s big names—Sea Ray, Axopar, XO, Bayliner, Quicksilver, Yamarin—and developed full in‑house capabilities from tooling to upholstery to metalwork. The W43 is where that industrial know‑how meets artisanal, slow‑build finishing. This is not an afterthought; it’s the culmination. 

Why W43

Modern‑classic lines, serious seakeeping: designed with a stepped, deep‑V hull for crisp handling and efficient running, then dressed in timeless proportions. Expect confident performance with twin Mercury V10 400s (standard) or optional triple 300s (like this one); independent tests and early listings report ~40‑knot top speeds when specified accordingly. 

Built the slow way: hand‑finished GRP structures, vacuum‑infused hard‑top, and limited production—an explicit commitment to craft over volume. 

Deck that transforms: powered drop‑down bulwarks port and starboard create instant terraces; an Opacmare full‑beam swim platform with integrated steps turns the aft end into a proper beach club—even on outboards. 

Real engineering pedigree: unveiled at Boot Düsseldorf and shaped with input from top European designers, this is a premium dayboat/weekender from a yard that already builds for the brands you know.

It’s a driver’s boat you can actually run in weather. 

Cockpit: proper wet‑bar (sink, Kenyon electric grill, Vitrifrigo drawer refrigeration) faces an L‑shaped lounge with a power‑lowering table—dine, then drop it to form a sunpad. Hit the switches and both bulwarks fold down to expand the deck footprint. Add the SureShade and you’ve got the right mix of sun and shelter. 

Stern: the Opacmare full‑beam platform with steps and a transom gate makes boarding and water access painless; underwater lights complete the scene. 

Below: an open‑plan cabin for two with a full‑size berth (sofa option), skylight and large hull windows, meticulous woodwork, and a separate head with a proper shower. The mirror/TV and fully dimmable lighting keep it civil after dark. Cabin A/C and a Webasto diesel heater are available for true shoulder‑season use. 

The build story (tradition + tech)

The Wiszniewski yard’s vertical integration—tooling, engineering, prototyping, windscreens, upholstery, metalwork, furniture, lamination and assembly—means tighter quality control and finish. That’s the “traditional meets modern” promise: hand work where it matters, advanced process where it counts. 

Performance & handling

A stepped hull with unusually deep deadrise, matched to twin or triple Mercury packages, delivers punchy acceleration, composed tracking and an easy 30‑to‑40‑knot envelope depending on spec. This is not a loud‑and‑light rocket; it’s tuned for real‑world sea‑keeping and range. 

In short: If you want a mass‑market 43, you have options. If you want a limited‑build, modern‑classic crafted by the team that’s already built boats for the biggest names—and now put their family name on the transom—the W43 is the honest choice. Build slots and configurations (twin 400s or triple 300s, upholstery and materials palette, audio upgrades, shade systems) can be tailored to your brief
