Formosa builds aluminium boats
with your safety in mind

Formosa Marine has always designed and built with safety and performance in mind and has tested in the most remote areas of Australia. The owners of Formosa Marine have never been complacent and look to improve and evolve the boats to handle all environments. Every Formosa boat complies with Australian standards of aluminium boat building and these are noted on the Australian Builders Plate issued to each boat. Other safety features include spacious layouts with no trip hazards and plenty of storage, stability and true self-draining decks for offshore adventures.


Why is a Formosa so spacious and stable?

Formosa is renowned for their spacious decks and if you compare to other designs, you’ll notice the space extends right through to the front. There has been a number of design decisions made on a Formosa Hull which combine to give you the amazing space you see when entering the boat. Formosa Marine have refined their hull design to include an ideal balance between the degree of deadrise, reverse chine, generous freeboard, wide beam and ergonomic layout, making you feel like you are in a much larger boat and more importantly, provides a stable platform for you to enjoy. A sharper deadrise may reduce travel time marginally and gives a much more narrow boat too, which isn’t pleasant during a long day in the rough, and with many people on board, space is probably more of a concern. Performance should include the whole day on the water, even at rest. We challenge you to see for yourself and compare to other boats on the market; the deck space will surprise you!


Formosa offers more stability

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 is an option now available on all models and sizes.

Even though every Formosa hull is naturally stable (with the wide beam and reverse chine hull), the Quad4™ Water Ballast offers an additional level of stability that really comes into its own under offshore conditions. Quad4™ Water Ballast is available on all models and sizes (standard on all models and sizes from March 2023).


PRO DECK™ True Self-draining Decks

A true self-draining deck quickly removes excess water from the floor area to the outside of the boat while in heavy seas, when a wave hits or just washing down the deck at home. You can now upgrade your boat to include the Formosa PRO DECK™ Self-draining Floor on all models 495 to 595. All Formosa hulls 635 and up carry PRO DECK™ as standard (standard on 635s from March 2023). Formosa’s PRO DECK™ is a true self-draining deck that is available in checker plate or carpeted aluminium (can also be finished in a flat-painted aluminium, ready for EVA marine flooring).

Formosa has designed a large drain channel welded in each corner of the transom which drains the water from the deck, through a v-cleat scupper system. 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 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.

For peace of mind, every Formosa hull is foam filled and an underfloor bilge pump is fitted as a standard feature.


Built for Safety

Every Formosa Marine boat complies with Australian standards and issued with a hull identification number (HIN) which is engraved on the Australian Builders Plate situated on the portside side pocket inside the boat. To meet these standards, there are various requirements, one of which is Buoyancy. Every boat should have a certain amount of flotation, installed in the boat, depending on size and weight, so as it continues to float when flooded, swamped or capsized.

Formosa Marine boats all have the recommended closed-cell foam fully packed underfloor. Closed-cell foam has excellent buoyancy and low water absorption. Coupled with Formosa’s high floor which not only gives massive strength to the subframe of the boat, but also allows far more flotation foam to fit underfloor adding even more safety to your boat.


Automatic Bilge Pump

For peace of mind, all boats are fitted with an automatic bilge pump with manual over-ride.

Electrical Harness Kit

Each boat has an electrical harness kit installed with Navigation Lights and Ancor Light.

Under Floor
Lock Cell Frame

Gives you structural reinforcement ensuring the main traffic areas are solid underfoot, providing the ultimate stability and a safe environment.


Heavy Duty Hand Rails

Strong 32mm extrusions are fully welded to the gunnels, forward and rear which runs to the floor line on the transom for safe boat access.

Transom Deck Tread

6mm EVA Marine Deck provides a durable, comfortable and safe underfoot surface.


The aluminium Bowroller is fully welded to the reinforced nose sheet and to the grab rails. Engineered to suit manual deployment and/or drum winches.


Side Pockets

Large side pockets welded to the ribs give extra side strength and plenty of storage.

Tiedown Transom Mounts

To ensure your boat is secure on the trailer, heavy duty tie down mounts are fully welded to either side of the transom.

Aluminium Anchor Well with Winch Mount

Formosa’s aluminium anchor well has a thick rear sheet/mounting plate incorporated into the design to support your electric anchor winch, so no need to request reinforcing.


Moulded Fuel Tank

The underfloor tank is especially moulded to fit into a Formosa hull and positioned central in the boat, under the floor to reduce fuel movement.

Battery Isolator Switch

Boats are factory fitted with a two battery isolator switch as standard.

Fuel Breather

Each tank is fitted with a sender unit and breathers to minimise air blockages.
