TH33 & TH38: Four Winns’ New Standard in Power Catamarans 

Four Winns has unveiled two new power catamarans—the TH33 and TH38—designed to bring added stability, usable space, and refinement to dayboating. Expanding the brand’s Twin Hull (TH) series, first introduced in 2023, both models will make their world debut at the Cannes Yachting Festival this September. 

The TH33 blends over 50 years of Four Winns craftsmanship with modern catamaran innovation. Measuring 33 feet in length with a 12’6″ beam, it offers over 400 square feet of deck space—equivalent to that of a 40-foot monohull. 

With wide twin hulls that reduce roll and increase fuel efficiency, the TH33 is purpose-built for social cruising. Its smart layout includes dual Garmin displays at the helm, a full-beam windscreen, and optional hardtop enclosure. A central galley with sink, fridge, and optional grill keeps gatherings seamless, while the spacious transom ladder offers easy water access. 

Inside, an optional Cabin Package adds a retreat below deck. Owners can personalise interiors with hand-stitched upholstery and refined marine-grade materials. 

The larger TH38 offers over 500 square feet of deck space and an expansive 14’8″ beam, accommodating up to 14 guests. Developed with Garroni Design and Marc Lombard, it includes two helm windscreen options: a full-height version for maximum seasonal protection or a low-profile setup for open-air cruising. 

Below deck, the TH38 houses two private, air-conditioned cabins with ensuite heads and large enclosed showers. Oversized hull windows flood the space with light, making it ideal for weekend stays. 

The TH38 also features modular deck seating, joystick piloting, and premium finishes throughout—blending cruising comfort with the flexibility of a family dayboat. 

Both models will premiere in the U.S. at the 2026 Miami International Boat Show.
