Comparison Guide


There has been comparisons between fibre glass boats and aluminium boats, and now more recently, pressed boats or plate boat. Formosa Marine has developed their boats to be one of the best in the aluminium plate boat market.

The Offshore High Tensile Hull.

Formosa Marine offer the Offshore range of boats (from 4.8m) which have High Tensile 5083 Marine Grade aluminium on side sheets and bottom sheets. If a boat manufacturer states that he is using 5083 grade in the hull, for example, be sure to ask him if it is 5083 in the side sheets as well as the bottom sheets. The 5083 grade aluminium is only available 4mm wide and if pressed it would likely crack under pressure. A lot of well-known plate boat manufacturers use 5052 side sheets, a softer grade to save money and allows them to press the sides.

The Formosa Offshore models are 4mm 5083 side and bottom sheets, with the exception of sizes 620 and over which have 5mm 5083 bottom sheets. The Formosa Classic models are 4mm 5052 side and bottom sheets and have the plate boat construction underfloor for extra strength. Be wary of boats masquerading as plate boats simply because they have flat side sheets with a lack of pressings. These pretend plate boats are most likely using aluminium sheet less than 4mm in thickness and are a completely different build to a Formosa.

The Formosa Weld.

Formosa Marine only uses the world’s Best Pulse Mig Welding Machines which are capable of laying down a beautiful looking and an extremely strong weld.

The quality welding machines ensures quality welds, therefore Formosa Marine leave the welds very visible and very strong. We don’t sand back their welds for looks. Owners can see how the boats are welded together, the strength and quality. It’s a feature we’re proud of.

Size does matter.

Formosa Marine measure their boats by hull length, from transom to the nose, and don’t include the Bowroller or other accessories on the boat. Other manufacturers measure and market their boats larger which may include the bowsprit and /or fittings.

If you see a Formosa 580 boat next to another manufacturer’s 615 at your next boat show, your eyes are not deceiving you, yes, the 615 looks like it would fit inside our 580 hull.



High Sides and Wide Beam.

Safety and boat performance while out on the water has always taken precedence in the design of the Formosa Hull design. Famous for our high sides and wide beam, you’ll get with a Formosa the extra protection and more comfort of a user friendly, large interior space and the extra stability on the water.

Don’t be fooled by performance ‘cowboys’ in their ‘skinny’ boats. A Formosa built boat is capable of going anywhere and in various weather conditions as other boats of like, even more capable when actually at your fishing spot. In a Formosa boat, your day out will be a more enjoyable one, with family or your fishing buddies, giving you heaps of room to move around and even utilise the transom, extending the boat‘s interior with the Active Transom design.

Other Manufacturers, with a sharper deadrise, boast an ability to cut through seas better than others but then try to hide the fact that their boats are so narrow. Their sharper deadrise may reduce time getting to your favourite fishing location by a few minutes but compromises your entire day out with your mates by having little internal deck space. The result being spending the day rubbing shoulders with your mates and apologising to each other for getting in the way.

True Self-draining Deck.

The Formosa Hull design allows the boats to have a high floor which is situated above the Chine line, or water line, giving you what we call a “true” self-draining deck on Formosa’s Offshore models.

On a Formosa, when the water drains off the deck it actually drains automatically out through two scuppers to the outside of the boat. Other manufacturers can’t do a full self-draining deck, as their floor is too low and below the outer water line, so the floors are unable to drain to the outside. Instead the water finds a way into the bilge for the pump to deal with. We’d hate to imagine what happens if the pump fails.

Be aware of these points: If you see an aluminium floor welded to the reverse chine in the bottom sheets of the hull, you have to realise that the structure under the floor is not as high as a Formosa boat. If you see a boat with low sides, it generally means it also has a low floor. If you see an aluminium floor with the only draining being a bilge pump in a bilge catchment box, this is because the floor is too low to be a true self-draining deck, which is the basis of a true plate boat.

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.

Questions to ask: Always ask if the boat has foam under the floor. Some manufacturers use air chambers which, if ruptured, are rendered useless. If an air chamber is leaking or punctured, the air escapes leaving the flotation and your safety on the water compromised.


The Formosa Counterbalance.

This evenly distributed counter balance has huge advantages over a central ballast. The stability of a Formosa hull is the best in the business and accentuated by the water ballast option available. Formosa has a unique COUNTERBALANCE 4 chamber system for extra stability at rest which extends across the width of the hull allowing water to enter the hull, minimising hull roll, sway from swell and internal boat movement. Once you’re on your way, the 4 chambers rapidly empty.

This optional extra is unique and unlike a more traditional central ballast used by other manufacturers. Our ballast is evenly distributed across the hull, so if one side of the boat dips due to internal movement or wave movement it has to pick up the ballast weight of the other side of the boat, creating a Counterbalance effect. If the ballast is central only, it can allow pivoting at the centre point which means that the boat is stable in the middle but not on the outer extremities of the hull.

If other manufacturers offer a water trap to keep water in the ballast tank for certain sea conditions, then ask why you need this feature to get home? We’d like to know because our boats get home every time. We don’t see a need for this feature other than for Marketing reasons.



The Formosa Difference.

Never before has an aluminium boat manufacturer designed a transom which allows the user to access all parts of their boat with ease and at no extra cost to the consumer.

The Active Transom, with 4 design options, offers more versatility and allows the user to utilise the last meter of their boat.

The Step Transom design allows for sitting on the rear pod in comfort or for better access into the boat. The design process allows for a flush folding transom door and seating extending the fishing platform or relaxing by the water.

It’s rare to see an Australian Aluminium boat company invest time, money and energy into value added designs like Formosa Marine does.

Other companies may take the safe and more economic option and follow industry standards. The only person who is effected is the consumer, forking out more money for less value.

No other aluminium boat manufacturer can match Formosa Marine’s range of choices and versatility for consumers.



Formosa Marine boats are proudly an Australian owned company building Australian Made products. Every Formosa boat complies with Australian standards of aluminium boat building and is issued with a hull identification number (HIN) which is engraved on the Australian Builders Plate attached to each boat. When you’re looking around for a boat to purchase, ask where other boat manufacturers are based. A lot of boats that are coming from overseas are getting around the rules that are required by companies that build boats in Australia. Safety and comfort is embedded in Formosa Marine’s basic structural boat design and are leaders in innovation, ensuring you can enjoy the Australian waters with a sense of ease. Formosa Marine has you covered.
