Four Winns has introduced two new power catamarans, the TH33 and TH38, extending its Twin Hull (TH) Series. The TH 36 launched in 2022. The models join a growing product line that includes bowriders, deck boats and cruisers. Founded in 1975 and headquartered in Cadillac, Michigan, Four Winns is part of the Beneteau Group and has built a reputation for combining American craftsmanship with modern European influences. The TH33 and TH38 are set to premiere at the Cannes Yachting Festival in September.
TH33: Compact and Comfortable
The TH33 is a 34-footer that “rivals the interior volume of a 40-foot monohull,” according to a company statement. With a beam of 12 feet 6 inches, it features over 400 square feet of usable deck space and multiple lounging zones to support short trips and longer excursions.
Stability is a key benefit of the twin-hull design. The TH33’s wide beam helps reduce roll, making it easier for passengers to be comfortable in choppier conditions. The boat is powered by twin Mercury outboards and can accommodate up to 600 hp total. A central transom ladder between the engines provides direct access to the water.
The helm includes forward-facing seats and a full-beam curved windshield. Electronics are integrated via twin 12-inch Garmin displays and a 7-inch passenger screen. An optional hardtop adds protection for all-season boating. The galley on the bridgedeck is equipped with a refrigerator, sink, and optional electric grill, positioned centrally to serve all social spaces.
TH38: A Catamaran for Cruising
At 38 feet 9 inches in length and with a beam of 14 feet 8 inches, the TH38 has over 500 square feet of deck space and accommodations for up to 14 guests. It is positioned between a high-performance dayboat and a compact cruiser, according to Four Winns. Buyers can choose between a high windshield with full enclosure or a low-profile windscreen for a more open-air experience.
Designed with input from Marc Lombard and Garroni Design in Genoa, Italy, the TH38 emphasizes versatility and comfort, with modular cockpit seating that shifts from lounges to a dining space. Joystick piloting, twin digital displays, and hand-stitched seats provide an upscale helm experience.
Below deck, the boat has two air-conditioned cabins, each with a private head and enclosed shower. Oversized windows add natural light, while storage and privacy elements support overnight stays. The TH38 is powered by twin Mercury outboards up to 700 hp max.
Both catamarans are designed to suit a wide range of boating lifestyles, offering customization options for layout, electronics, and finishes. Their U.S. debut is scheduled for the 2026 Miami International Boat Show.
