Four Winns is expanding its Twin Hull series launched in 2023 with the new 33-foot power catamaran TH33.

The new Four Winns TH33 was designed as a day boat and is intended to offer more stability, efficiency and space than comparable monohulls thanks to its twin-hull construction. With a width of 3.81 metres, it provides over 40 square metres of usable deck space.

Space concept and stability

The TH33's twin hull ensures good weight distribution on the water surface. This reduces rolling movements and increases driving stability, even in waves. The boat requires less engine power than comparable monohull boats with a similar amount of space.

The helm station is equipped with two wide seats. The instrumentation includes two 12-inch Garmin displays and a separate 7-inch display. A full-length windscreen in the typical Four Winns design offers protection from the wind. A hardtop with all-round glazing is available as an option, offering year-round weather protection.

Equipment and functionality

The TH33 has a centrally positioned galley with sink, waste bin and refrigerator. An electric grill can be integrated on request. Access to the toilet is via a wide entrance.

At the stern, between the Mercury outboard engines, there is a generous bathing ladder for direct access to the water. The deck areas are fitted with real wood flooring or optionally with colour-coordinated marine flooring.

The TH33 offers generous storage space below deck. With the optional cabin package, this area can be transformed into a retreat for relaxing breaks.

Options for the interior

Various interior options are available, including hand-stitched seats in cognac-coloured leather or a light grey interior. All upholstery is made from marine-grade materials that can withstand the demands on board.

Four Winns offers various customisation options for the TH33. These include, for example, flexible seating arrangements and various equipment packages. The Four Winns TH33 will celebrate its premiere at the Cannes Yachting Festival 2025.
