Formosa Boats Range
Every Formosa Marine boat in the range shares the same SRT™ engineering DNA, whether it's the pint-sized GRT 425 or the flagship 675 hardtop. Two families cover the lineup: GRT for buyers wanting a light, capable starter rig, and SRT™ for those chasing six generations of hull development underneath them. Pick your size, pick your layout, and the Mullies Marine team will sort the rest.
GRT Range – Compact & Capable
The GRT range spans 4.25m to 4.55m, available in tiller steer and console layouts. These are the entry point into Formosa ownership: light to tow, easy to launch, and still built from 4mm high-tensile plate rather than a pressed hull. Don't let the size fool you — these smaller rigs punch above their weight. GRT stands for Guts, Resilience, Toughness, and the boats earn the name on estuaries, rivers and smaller trailer setups.
Local knowledge: Chasing gummies and King George whiting in Port Phillip Bay calls for a different hull to running wide out of Westernport for snapper. Not sure which size and layout suits your patch of water? The Mullies Marine team fishes these waters too — give them a call before you buy.

Why Formosa & Why Mullies Marine?
Australian-Made Since 1998
Formosa has been designing and building aluminium boats in Brisbane since 1998, and the brand is now into its sixth generation of hull design. What began as one boat builder's passion for fabrication near Moreton Bay has grown into one of Australia's most respected plate boat manufacturers. Over 26 years of refinement means every hull is purpose-built for Australian conditions, not adapted from an overseas design.

Quality Build
SRT™ Aluminium Plate Hull
Every SRT™ hull starts as 4mm or 5mm 5083 high-tensile aluminium plate, the grade favoured in marine and structural applications where strength can't be negotiable. Lock-cell hull and deck construction ties the whole structure together for real rigidity, and an enhanced deadrise paired with a large reverse chine delivers a smooth, dry ride when conditions turn on you mid-session.
Formosa moved to digital hull engineering from 2021, using CNC-cut components and targeted robotic welding to cut variation between builds. Every hull leaving the Lytton, Brisbane facility now traces back to a fully validated 3D model.
4-Year Structural Hull Warranty
Formosa boats Brisbane-built from 2018 onwards carry a 4-year structural hull warranty to the original purchaser, backed by a 1-year warranty on factory-fitted parts and accessories. Every hull is engineered specifically for Australia's toughest waters, with a Queensland manufacturing heritage — Formosa Boats Queensland has produced since 1998 — that shows in every weld.
