Everyone can safely enjoy the joy of boating with the Formosa Enclosed Centre Cabin, designed for full walk-around access and reliable weather protection. This model features a fixed hardtop with a glass windscreen, sliding side ventilation windows, heavy-duty grab rails, and a rocket launcher with seven rod holders. Positioned on a slightly raised casting deck, the walk-around cabin offers enhanced visibility and easy access to the anchor well, making it practical for a range of conditions.
Inside the Enclosed Centre Cabin, you will find carpeted bunks, cabin side pockets, and a footwell with a centre board, providing convenient storage and space for a portable toilet. From March 2023 onwards, all new orders also include a front seat off the cabin, a ventilation hatch, and bunk cushions as standard. Awning tracks welded to the hardtop allow for the installation of clears or canvas to enclose the rear of the cabin, offering additional protection from the elements.
For driver and passenger comfort, the Enclosed Centre Cabin includes two embroidered, high-back folding seats mounted on Aluminium Seat Boxes—now standard. Choose between storage hatches or an open esky provision for your seat boxes to best suit your needs.
Standard features of the Enclosed Centre Cabin include an Electric Motor Mount, six aluminium rod holders on the gunnels, 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, and three cleats. The boat is finished in white paint with Formosa graphics, giving it a polished and durable look. Additionally, an optional underfloor 80L auxiliary tank for fuel or water is available for boats 635 and over.
Formosa boats are well known for their stability, and the Quad4™ Water Ballast system further enhances this feature, particularly in offshore conditions. From March 2023, the Quad4™ Water Ballast system will be included as standard in all new Enclosed 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.
