Half Cabins

The Formosa Half Cabin gives the ultimate protection from the weather for you and the family with plenty of storage under the bunks.

The large cabin is ideal for overnight stays providing a long bunk area for a comfortable sleep and greater storage for adding amenities such as a portable toilet. In a half cabin the driver and passenger sit behind a windscreen while underway and you gain access to the anchor well through a large hatch accessible inside the cabin. With the Formosa Half Cabin you can upgrade by choosing from three (3) Hardtop optional extras; the Folding Rocket Launcher with Aluminium Hardtop Visor with awning rails, a Lockable Roller Door for cabin security when leaving the boat, or the Fixed Open Cabin Hardtop. The Formosa Aluminium Half Cabin has cushioned cabin bunks and centre board, carpeted walls for comfort, two side windows, an extra-large hatch and windscreen. Enjoy the comfort of two (2) embroidered, High Back, Contoured Bolster Seats mounted either on Aluminium Storage Seat Boxes for OFFSHORE models, OR, on the CLASSIC models you get two Air Ride Adjustable Pedestals giving you more comfort underway. Standard features on a Half Cabin include Folding Rear Lounge, a flush folding transom door, a large aluminium Bowroller, 32mm handrails, Tow-Catch™ Trailer capability, heavy duty dive ladder, quality steering, moulded fuel tank and sender with filter, automatic bilge pump, transom deck tread, foam filled hull, electrical harness kit, 2 cleats, 2 rod holders (620 over – 4), forward bollard, white paint and Formosa graphics, plus more. Formosa boats are known for their stability, yet the Quad4™ Water Ballast option is available if you need more stability at rest.
