QUALITY BUILD WITH STRENGTH TO LAST A LIFETIME.

Dedicated to building quality boats

Formosa Marine stay focus on building Aluminium plate boats to order. The aluminium boats are designed and built in Brisbane, Tingalpa and are Australia’s best for strength, stability and versatility. Each boat has the same engineered specifications so you can be assured that Formosa Marine’s plate boat construction, spacious layout and freeboard is in each hull, regardless of the size or model. Working closely with dealers and local Formosa boat owners, Formosa Marine brings the strength and designs you need for Australian conditions. Others can only talk about what makes an aluminium plate boat, Formosa Marine builds them. Continue below for information on their New Formosa SRT Plate Hull design.

Formosa SRT Plate Hull – 2019

The New Formosa SRT Plate Hull combines the very best boat designs from the SEA-ROD and Tomahawk brands, packaging them into one skilfully engineered plate boat and rebranded as Formosa SRT. The new plate hull features the ultimate level of performance, handling and stability, which includes a stronger Lock-cell hull and deck structure with a Quad4™ Water Ballast option available across the whole boat range. An increased deadrise, custom built cambered strakes and large reverse chine create hydrodynamic lift and superior traction. In addition, Formosa SRT Plate Hull uses the Formosa Step Down ‘Active Transom’ design giving smart storage solutions, easy on-board battery access, four (4) fantastic ‘Active Transom’ designs to choose from and superior, removable, flush folding door and seating systems…

 

Step Down ‘Active Transom’ Design

Get the most out of your transom with the Formosa SRT Plate Hull which uses the Formosa Step Down ‘Active Transom’ design. This innovated design utilises the area in the back of your boat that is usually forgotten, the Transom.  A Formosa boat gives you smarter storage solutions, easy on-board battery access, four (4) fantastic ‘Active Transom’ designs to choose from and superior removable flush folding systems with many optional extras to suit such as a removable Bait Board with Bait Tank which can be swapped for the Ski Pole option.

Flush Folding Systems

Formosa has designed the new hull to incorporate flush folding sytems to increase your platform. The transom door and folding lounge can fold down to create more sitting areas or fishing platforms. Fold away flush against the side of the boat when not in use for a clear deck area to move around. The folding lounge is removable.

Quad4™ Water Ballast Option

The innovative Quad4™ Water Ballast is a unique four (4) chamber COUNTERBALANCE system and developed for unrivalled stability at rest. Unlike traditional keel ballasts, the Quad4™ off-centre ballast hull combined with a wide beam and reverse chine hull, minimises hull roll from the swell or internal passenger movement. Once you are on your way, the 4 longitudinal stringers empty rapidly, allowing you to get on the plane without any change in performance. This is an option now available on all models and sizes.

Lock-cell Structure

Formosa uses extra wide longitudinal stringers which provide market leading strength along the length of the mid ship, covering a much wider surface area than the traditional stringer. These unique box chambers ensure hull and deck rigidity and shape integrity.

Increased Deadrise

The Formosa SRT Plate Hull has had an increase to 19 degrees which isn’t a huge change, as stability is still a discerning factor in a Formosa designed hull. The plate hull design has influenced the new 490 size (was 480) which has seen a significant increase to 16 degrees.

Cambered Strakes

The new Formosa SRT hull demonstrates an excellent ‘out of the hole’ response and minimises the risk of broaching. The cambered strakes create hydrodynamic lift and superior traction and handling. Using principals of air wing design, the cambered design changes the water flow, breaking up the ‘sticky water’ (a key force that inhibits nose trim and in turn creates a wet hull). The cambered strakes also feature a unique tapered body so the risk of aeration is minimised, ensuring optimum prop and fish finder performance.

Reverse Chine

A Formosa Hull has large 170mm wide reverse chine with a negative angled chine extrusion. The reverse chine and cambered strakes help with traction performance, particularly with transom slide in tight turns.

True Self-draining Decks

A self-draining deck quickly removes excess water from the floor area which may occur when caught in heavy seas or while hosing down the deck. The Formosa Aluminium Self-draining Deck is a standard feature on the OFFSHORE models. Formosa has designed a large drain channel welded in each corner of the transom which drain the water from the deck, through a scupper on the back transom and to the outside of the boat. It’s what Formosa calls a ‘TRUE’ self-draining deck as the drainage system sits ABOVE the waterline, allowing the water to leave the boat. This is thanks to Formosa’s Hull design which allows for a high floor that sits above the chine line or water line. Other ‘draining decks’ on the market are welded on the chine line, or below the waterline, and so direct the water into the hull requiring the water to be pumped out of the boat; a scary proposition if the bilge pump is out of action. The Formosa aluminium deck is carpeted with marine grade quality flooring, making it a great non slip surface that is comfortable from the sun’s heat. For peace of mind, the hull is foam filled and an underfloor bilge pump is fitted as a standard feature.

 

Formosa offers more strength

Formosa Marine uses the world’s best Pulse Mig Welding machines to ensure an extremely strong and quality weld, and are proud not to sand back welds for looks, leaving the integrity and strength of the hull visible to customers.

Plate Boat Construction

FORMOSA MARINE builds a plate boat construction with a superior underfloor lock-cell design giving the floor structural reinforcement, ensuring the main traffic areas are solid underfoot and provides greater overall hull strength to handle the rigours of open water boating. Box style side ribs act as support and house wiring and tubing internally to keep your deck clean and free of obstructions. Be assured of a strong hull built to withstand open water conditions and provide many years of trouble free boating.

High Tensile Hull

Formosa builds their boats with no less than 4mm aluminium bottom sheets AND side sheets. With Formosa’s plate boat construction you get a very strong hull in which, unlike boats built with 3mm sheets or less, require no pressings to strengthen. The Formosa OFFSHORE hull is built with 4mm High Tensile 5083 Grade Aluminium sheets, including the sides. Due to customer demand, boat sizes 620 and over have 5mm 5083 bottom sheets for extra strength and the option to upgrade to 5mm is available on the OFFSHORE. The CLASSIC hull is built with High Strength 5052 Marine Grade Aluminium with 4mm side and bottom sheets.

32mm Hand Rails

Strong 32mm extrusions are fully welded to the gunnels, forward and rear to give you a strong hold on the boat, whether you are on board or at the boat ramp. The rear rail runs over the back of the transom to floor height which give you excellent support while exiting or entering the boat and a safe hold when swimming in the water. These grab rails are built strong for attaching aftermarket accessories, fenders and tying off your boat.
