Four Winns Debuts TH33 and TH38 Power Catamarans
Aug 5, 2025
Introducing The Twin Hull Power Catamarans That are Enhancing Space, Stability, and Sophistication on the Water.
Engineered to transform boating experiences into refined escapes, the new Four Winns TH33 and TH38 set a new standard for power catamarans of its size as the latest addition to its TH (Twin Hull) Series, launched in 2023.
NEW TH33: REDEFINING HORIZONS WITHOUT COMPROMISE

The TH33 blends Four Winns’ 50 years of premium American craftsmanship and iconic design with bold innovation. Building on the success of the first launch in the series, the TH33 is an instinctive power catamaran meticulously designed for those who demand more space, more stability, and more memorable days on the water. “The TH33 is a unique concept that simply brings more to boaters,” says Four Winns Product Manager Alexis Chas. “The TH33 is more than a new addition to the TH line—it’s a bold new step in redefining the experience of boaters.”
More Space, Stability and Efficiency
The TH33’s power catamaran design impressively offers boaters the space of a 40’ (12.92m) monohull. Using the entire 12’6” (3.81m) beam of the 33-footer, over 400 square feet of versatile living space is available for relaxing, entertaining, and enjoying sun-filled days cruising on the lake or through coastal waters. The width between the twin hulls brings enhanced stability. Its wide stature distributes weight evenly across a broader footprint than monohulls, significantly reducing roll motion. This enhanced stability transforms every moment onboard into a more enjoyable, safer, and more effortless experience for everyone aboard. Increased stability also maximizes efficiency. While boasting the living space and comfort experienced on a larger size monohull dayboat, the TH33 navigates smoothly through the water with less drag. Reduced drag decreases the amount of power and fuel required to obtain a comfortable speed, giving the boat a significant advantage over monohulls and offering a brand new and desirable life on the water for Four Winns boaters.

NEW TH38 : REDEFINING WHAT A DAYBOAT CAN BE

The TH38 is enhancing onboard protection, expanding living space, and pushing the boundaries of functional ingenuity and comfort—while maintaining the stability, accessibility, and performance the TH Series is built upon.
Eliminating Limitations, Extending Safety
The TH38 masterfully blends the adventurous spirit of a dayboat with the refinement and livability of a cruiser. Designed in collaboration with Garroni Design and naval architect Marc Lombard, the TH38 introduces two helm windshield versions: a full-height windscreen for maximum protection and seasonal comfort, or a low-profile version that enhances airflow and open-air freedom. “The TH38 removes boundaries for boaters, including where and when they can enjoy the finer side of life aboard a Four Winns boat,” states Four Winns Product Manager Alexis Chas. “The twin hull structure delivers a smooth ride and superior stability whether cruising on inland waters or exploring coastal waters in the South of France, and our new features offer new opportunities.” Four Winns boaters can comfortably enjoy year-round boating with the TH38’s full-height windscreen and new sport-top options. “The high windshield and enclosure enhance comfort and safety while extending the boating season,” says Alexis Chas. The low windshield option maintains the spirit of an open boat while including optional protection on the sides of the cockpit. With its modular cockpit seating layout, the versatility of the boat’s deck allows occupants to craft their experience while safely traveling through the center of the boat. From an open social space to a unified dining area, the TH38’s deck instantly transforms to meet the wants and needs of the moment.
