Tougher Than Your Average Tinnie
Size: 4.55m
Formosa’s new small plate range brings the durability of a plate production build into a small boat package. Innovation is at the heart of everything we do at Formosa Marine, and this ethos is evident in the release of the GRT range.
With the GRT series, Formosa has launched back into the small boat market with a compact yet formidable model—delivering toughness, stability, internal volume, and an exceptional ride that stands out among Australian production boats.
Built with 4mm 5083 high tensile bottom sheets, 4mm plate sides, and fully welded top decks, the Formosa GRT range is far superior to your typical pressed and stitched production tinnie that has been the norm in the Australian market. The generous V-hull, large beam, and big negative reverse chine hull combine to offer unmatched strength, performance, and stability.
With high sides providing ample internal freeboard and smart storage solutions, the GRT package is designed for fishos seeking a boat that exceeds expectations in an affordable, easy-to-handle format.
