Ronstan's history began in 1953 in Australia when Ron Allatt and Stan Lenepveu, driven by their love for sailing and craftsmanship, started building wooden-hulled boats. Recognizing the need for high-quality deck fittings, they established Ronstan Marine Equipment Pty Ltd in Highett, Melbourne. Today, Ronstan is a leading supplier of marine hardware for sailboats, motorboats, and yachts. Their commitment to quality, innovation, and sustainability has made them a trusted brand worldwide. Their story embodies the Australian spirit of resourcefulness and dedication, ensuring smooth sailing for future generations. Fisheries Supply stocks the extensive catalog of Ronstan marine products from blocks, Orbit winches, travelers, and sail controls to technical apparel and deck hardware. Ronstan develops their globally trusted sailing gear alongside professional teams, leveraging insight across sail shape analysis, rig loads modeling and competitive testing. This rigorous development ensures Ronstan sailing equipment like fairlead, boom bails, mast hounds and RF genaker furlers deliver optimized performance suited for racing multihulls and offshore monohulls alike. From racing dinghies to workboats, we supply Ronstan sailing accessories crafted for any vessel, like the flexible neoprene pants with grip knee patches designed through research on muscle activation and joint angles. Contact our representatives to determine the ideal Ronstan products from our vast inventory of deck hardware, sail controls and technical gear purpose-built for sailors.
