A Perfect Overnight Escape
Sizes available: 6.35, 6.75
The Formosa Enclosed Half Cabin is designed with a fixed cabin, featuring a glass windscreen, two side sliding windows, and an open connection to the rear deck. Ideal for overnight stays, this cabin layout includes cushioned bunks for a restful sleep and large storage areas for all your essentials. The cabin offers an open-plan experience, while awning rails are welded to the hardtop structure, allowing for the addition of canvas or clears to enclose the cabin if desired.
The Enclosed Half Cabin features cushioned bunks with a centreboard, carpeted walls for added comfort, a large hatch for easy access to the anchor well, heavy-duty handrails, and seven rod holders for your fishing needs. The open design of this cabin makes it versatile, providing both comfort and practicality for family trips or fishing expeditions.
For added driver and passenger comfort, the Enclosed Half Cabin includes two embroidered, high-back Bolster Seats, mounted on Aluminium Seat Boxes—now included as standard. You can choose between storage hatches or an open esky provision for your seat boxes to best suit your needs. For extra security, you can upgrade with an optional Lockable Cabin Roller Door. Additionally, an underfloor 80L auxiliary tank for fuel or water is available for boats 635 and above, offering added convenience for extended trips.
Standard features of the Enclosed Half Cabin include four aluminium rod holders on the gunnels, a folding rear lounge, Single Access Active Transom, 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, modern appearance.
Formosa boats are known for their stability at rest, and the Quad4™ Water Ballast system further enhances this feature, especially in offshore conditions. From March 2023, the Quad4™ Water Ballast will be included as standard on all new Enclosed Half 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.
