Ronstan

<h3>About Ronstan – A Legacy Built on the Water</h3><p>Few names in the sailing world carry as much weight as Ronstan. <strong>Founded in 1953</strong> by Ron Allat and Stan Lenepveu, the company began as a small boatbuilding operation in Highett, a suburb of Melbourne, Australia. What started as handcrafting custom yacht fittings for fellow sailors at the nearby Black Rock Yacht Club steadily grew into one of the most respected sailboat hardware manufacturers on the planet. The brand name itself is a nod to its founders — Ron and Stan — whose passion for sailing and precision craftsmanship shaped the company's DNA from day one.</p><p>Today, <strong>Ronstan International</strong> is a globally recognised manufacturer and supplier of sailboat hardware, rigging components, winches, sailing gear, and accessories, with its head office remaining in Braeside, Victoria, Australia. The company has established manufacturing facilities in Australia, Denmark, and Indonesia, along with sales offices in the United States, and distributes products to sailors in over 40 countries around the world. In November 2023, Ronstan joined <strong>Groupe Wichard</strong>, aligning with an industry leader whose portfolio spans more than ten world-renowned brands in the sailing and safety markets — a move that further strengthens Ronstan's global reach and product offering.</p><h3>Engineered for Every Sailor, Proven at the Highest Levels</h3><p>Ronstan's reputation spans the full spectrum of sailing — from first-time dinghy sailors to elite competitors at the America's Cup and Olympic Games. The brand serves as the official supplier to the Australian Sailing Team, and Ronstan hardware has appeared aboard medal-winning boats across multiple Olympic campaigns. That pedigree at the pinnacle of racing directly fuels the innovation available to everyday sailors: the demanding performance requirements of top-tier competition have driven many of the technical breakthroughs found throughout Ronstan's broader product range.</p><p>The company's catalog encompasses well over 2,000 products, including pulley blocks, traveller systems, furlers, rope cleats, stainless steel fittings, shackles, snap shackles, and winches. Whether you're outfitting a small racing dinghy, a family cruiser, or an offshore race yacht, Ronstan offers hardware designed and tested to perform in real-world conditions. Their in-house capabilities span design, engineering, precision injection moulding, CNC machining, metal pressing, and assembly — all of which contribute to the consistent quality sailors have come to expect from the brand.</p><h3>Top Ronstan Product Categories</h3><p>Among Ronstan's most popular product lines are their <a href="/11561-ronstan-tiller-extensions-accessories-202641">Tiller Extensions &amp; Accessories</a>, which encompass both their renowned carbon fibre and alloy tiller extension ranges.

Arrived in good working order.

Nice!

Good experience, however, I was hoping that 'FREE SHIPPING' would be the standard for Autoplicity.

After reading several negative reviews, I was suspicious of the low price offered by Autoplicity but decided to try them out anyway. Much to my surprise, the belt for my car shipped immediately and arrived 2 days later via ground shipping from half way across the country. I was very pleasantly surprised with the speed of service and got my parts for the lowest price on the internet. A+!

Good
