Quality Build

Quality - built to last a lifetime

Dedicated to building quality boats

Formosa Marine focuses on building aluminium plate boats made to order. Designed and crafted in Lytton, Brisbane, the Formosa range offers Australia’s best in strength, stability, and versatility. Every Formosa SRT™ Plate Hull shares the same high-quality engineering across the range, ensuring you get durable construction, spacious layouts, and superior freeboard in every model. Collaborating closely with dealers and local Formosa boat owners, we deliver the strength and design needed for Australian conditions. While others may talk about what defines an aluminium plate boat, Formosa Marine builds it.

Formosa SRT™ Plate Hull

Born from six generations of hull design and over two decades of Australian plate boat craftsmanship, the Formosa SRT™ sets the benchmark for design, performance, quality workmanship, and innovation. Formosa has combined the best features of their SEA-ROD and Tomahawk brands to create the SRT™—an exceptional hull that prioritizes functionality, strength, aesthetics, safety, and value.

The SRT™ Plate Hull offers a smooth, dry ride with improved handling in all conditions thanks to:

  • Enhanced hydrodynamic lift and superior traction with:
    • A new improved deadrise,
    • Large reverse chine.
  • A stronger Lock-cell hull and deck structure.
  • 4mm 5083 High Tensile bottom sheets on every boat.
  • ‘Active Transom’ design with flush folding systems.
  • The Quad4™ Water Ballast, available across all models.

Refinement

The Formosa boat range has evolved, combining the strengths of the Tomahawk and SEA-ROD into one great design—the SRT™ Plate Hull.

All Formosa SRT™ hulls are available with PRO DECK™—Formosa’s true self-draining deck system, optional on models 495 to 595, and standard on boats 635 and up.

Standard features on the Formosa SRT™ Plate Hull include:

  • Premium Dometic Hydraulic Steering with Genuine Outboard Hoses – Experience precise boat control when it matters most. Unlike lighter gauge steering systems, the Genuine Dometic system with genuine outboard hoses offers incredible responsiveness in all conditions.
  • Transom Door – Designed and built in-house, the self-supporting Formosa folding transom door folds up flush with the transom and doubles as a small casting platform or seat.
  • Aluminium rod holders – For strength and durability, aluminium rod holders are fitted to the gunnel of every boat.

Active Transom

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 rear area 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 a removable Ski Pole.

Flush Folding Systems

Formosa has designed the new hull to incorporate flush folding systems 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 with an innovative ‘Off Keel’ counterbalance design that is industry-leading in terms of achieving even greater on water stability. Unlike traditional keel ballasts, the Quad4™ four (4) chamber ballast, 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 feature is now standard on all models and sizes from March 2023.

Lock-cell Structure

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

Stability, traction & performance

Increased Deadrise

The Formosa SRT™ Plate Hull has had an increase to 19 degrees on hull sizes from 525 to 715, increasing ride comfort & traction. The 755 includes a 20 degree deadrise and the 495 has seen a significant increase to 16 degrees.

Reverse Chine Hull

Reverse Chine

Stability is a discerning factor in a Formosa designed hull and the Formosa SRT™ Plate Hull has a large 170mm wide reverse chine with a negative angled chine extrusion for increased stability, traction & performance.

True Self-draining Decks

A true self-draining deck is designed to quickly remove excess water from the boat’s floor, whether you’re navigating heavy seas, taking on a wave, or simply washing down the deck at home. Formosa’s PRO DECK™ Self-Draining Floor is now available as an upgrade on all models from 495 to 595, and comes standard on all hulls 635 and up. The PRO DECK™ system is available in checker plate or carpeted aluminium, with an option for flat-painted aluminium—ready for EVA marine flooring.

Formosa has engineered large drain channels welded into each corner of the transom, directing water out of the deck through a V-cleat scupper system. This makes the PRO DECK™ a true self-draining solution, as the drainage system is positioned above the waterline, allowing water to naturally exit the boat without the need for pumping. Thanks to Formosa’s high-floor hull design, which sits above the chine line, the system provides efficient drainage even in challenging conditions. In contrast, many so-called ‘self-draining’ decks on the market have drains below the waterline, requiring bilge pumps to remove water—an unsettling risk if the bilge pump fails.

For added peace of mind, every Formosa hull is foam-filled, and an underfloor bilge pump is fitted as a standard feature. This multi-layered approach to safety ensures that your boat remains secure and stable, no matter what the conditions throw at you.

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.
5083 High Tensile Hull

Formosa builds their boats with 4mm aluminium bottom sheets AND side sheets. With Formosa’s plate boat construction, you get a very strong hull which requires no pressings to strengthen, unlike other boats built with 3mm sheets or less. Due to customer demand, boats 635 and larger have 5mm 5083 bottom sheets for extra strength and durability. The option to upgrade to 5mm bottom sheets is available on other boat sizes.

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.
