Sizes available: 5.65m, 5.95m, 6.35m, 6.75m
The Formosa Centre Cabin is the ideal family boat, offering a safe and enjoyable way for you and your kids to experience the joy of boating. With walk-around cabin access and the ability to seek shelter from the weather, the Centre Cabin ensures comfort and security on the water. Positioned on a slightly raised casting deck, the cabin provides an elevated view of your surroundings and easy access to the anchor well, making every trip both practical and enjoyable.
The Formosa Centre Cabin features a windscreen, carpeted cabin bunks, cabin side pockets, and a footwell with a centre board for additional storage and a portable toilet area. New orders from March 2023 now also include a front seat off the cabin, a ventilation hatch, and bunk cushions as standard, enhancing the comfort for all passengers.
The Centre Cabin also comes standard with the popular folding Rocket Launcher with an Aluminium Hardtop Visor for added sun protection, including fixing points for clears and rod storage. The Rocket Launcher folds down towards the transom, providing excellent home storage options. Awning tracks are welded to the Hardtop Visor, allowing for the installation of clears or canvas for even more protection from the elements.
For driver and passenger comfort, the Centre Cabin is equipped with two embroidered, high-back folding seats mounted on Aluminium Seat Boxes—now included as standard. Choose between storage hatches or an open esky provision for your seat boxes to best suit your needs.
Standard features of the Centre Cabin include an Electric Motor Mount, a large aluminium bowroller, 32mm handrails, Tow-Catch™ Trailer capability, a heavy-duty dive ladder, quality steering, a moulded fuel tank with sender and filter, automatic bilge pump, transom deck tread, foam-filled hull, electrical harness kit, three cleats, and four aluminium rod holders (six on models 635 and above). The boat comes finished in white paint with Formosa graphics, giving it a sleek and modern appearance.
Formosa boats are celebrated for their stability at rest, and the Quad4™ Water Ballast system further enhances this stability, especially in offshore conditions. From March 2023, the Quad4™ Water Ballast will be included as standard on all new Centre Cabin orders.

Why Choose a Formosa for Space and Stability?
Formosa boats are renowned for their spacious decks, extending all the way to the bow. Several key design elements combine to create this generous space, including the perfect balance of deadrise, reverse chine, wide beam, generous freeboard, and ergonomic layout. These features make the boat feel larger than its size, offering a stable platform for all-day enjoyment on the water.
While some boats with sharper deadrises may cut travel time slightly, they often sacrifice comfort and space—especially on long, rough days with multiple passengers. At Formosa, we believe performance isn’t just about speed, but also about comfort at rest. Compare a Formosa to others on the market and you’ll be surprised by the space it offers.
4-Year Structural Hull Warranty
Formosa Marine offers a 4-year warranty on the hull structure to the original purchaser, covering any defects in material or workmanship on all hulls built from 2018 onwards. Additionally, there’s a 1-year warranty for all Formosa Marine factory-fitted parts and accessories, including cabins, launchers, tops, fittings, and optional extras, which may experience movement with use.

Quad4™ Water Ballast System
The innovative Quad4™ Water Ballast system features an industry-leading ‘Off Keel’ counterbalance design, providing unparalleled on-water stability. Unlike traditional keel ballasts, the Quad4™ uses four chambers, combined with a wide beam and reverse chine hull, to minimise hull roll caused by swells or internal passenger movement.
When underway, the longitudinal stringers empty rapidly, allowing the boat to get on plane seamlessly without compromising performance. This advanced system is now standard on all Formosa models from March 2023, offering you a stable and smooth ride, no matter the conditions.
