Ronstan

<h3>Ronstan: Precision Sailing Hardware Built for Every Sailor</h3><p><strong>Ronstan</strong> is one of the most respected names in sailboat hardware — and with good reason. <a href="/11561-ronstan">Ronstan</a> traces its roots back to 1953, when two Australian sailors, Ron Allatt and Stan Lenepveu, founded Ronstan Marine Equipment Pty Ltd in Melbourne, Australia. What started as a passion project supplying handcrafted yacht fittings to their local sailing club gradually grew into a global enterprise recognized for engineering excellence and real-world performance.</p><p>Today, Ronstan is headquartered in Braeside, Victoria, Australia, with international offices in the United States and Denmark, and production facilities across three continents. The brand distributes to more than 40 countries and handles upwards of 4.9 million units out of its Melbourne facility every year. In November 2023, Ronstan joined Groupe Wichard, further cementing its place among the world&apos;s most influential marine hardware groups.</p><h3>Engineering That Performs On the Water</h3><p>What sets Ronstan apart from generic marine suppliers is its deep commitment to innovation and in-house manufacturing capability. Ronstan&apos;s engineering teams — spread across Australia, the United Kingdom, and Denmark — draw on diverse sailing traditions to develop products that meet the demands of wildly different markets: from club dinghy racers to offshore bluewater cruisers. The brand&apos;s catalog spans blocks, winches, travelers, furling systems, batten systems, stainless steel rigging hardware, and a full suite of deck gear. Ronstan is also the official hardware supplier to the Australian Sailing Team.</p><p>The brand&apos;s in-house manufacturing includes precision CNC machining of aluminum, brass, and stainless steel, as well as advanced plastic injection molding using high-performance engineering polymers — including composites reinforced with up to 60% long-strand glass and carbon fiber. This vertical integration means Ronstan controls quality from design to delivery.</p><h3>Core Product Categories</h3><p>Three categories stand out as workhorses of the Ronstan lineup. <a href="/11561-ronstan-fairleads-200387">Ronstan Fairleads</a> are purpose-designed to guide, contain, and correct the lead angle of control lines across a range of deck configurations — a deceptively simple piece of hardware that plays a critical role in clean, friction-free sail handling. For securing lines under load, <a href="/11561-ronstan-cleats-200268">Ronstan Cleats</a> offer a comprehensive range spanning jam cleats, vee cleats, and the brand&apos;s well-known C-Cleat&trade; and T-Cleat&trade; cam cleat families, each engineered for reliable cleating and easy release in all conditions. Completing the rigging equation, <a href="/11561-ronstan-shackles-200937">Ronstan Shackles</a> — including the innovative Triggersnaps&trade; snap shackle range — are individually proof-load tested and designed for intuitive one-handed operation, making them a trusted choice for racers and cruisers alike.</p><h3>From Dinghies to Maxis</h3><p>One of Ronstan&apos;s most distinctive qualities is its breadth. The same brand that equips Olympic-class dinghies also supplies hardware to some of the largest and fastest offshore racing yachts in the world. Whether you&apos;re outfitting a small club boat or a serious offshore campaigner, Ronstan&apos;s catalog has a solution engineered to the right weight, load rating, and finish for the task at hand.</p>

Product Details

The Ronstan 20ST Orbit Winch sets a new standard for high-performance alloy winches in marine applications. Combining innovative design with proven manufacturing expertise, this single-speed winch delivers exceptional performance while weighing significantly less than comparable models in its class. The remarkably low line entry height improves ease of use and efficiency on deck.

Power Ribs™ Technology:

The machined aluminum drum features Ronstan's distinctive Power Ribs™ technology, proven on Andersen Stainless Steel Winches. This unique ribbed profile provides exceptional line grip while minimizing rope wear. The superior grip requires fewer wraps around the drum, reduces load on the self-tailer, and encourages lines to slide smoothly upward to prevent riding turns. Even under high loads, the non-abrasive surface allows smooth, controlled easing.

Tool-Free Maintenance:

Complete disassembly and reassembly can be performed without any tools. Simply pull back the spring-loaded release latch and rotate the self-tailing arm slightly counter-clockwise to remove it from the center stem. The drum then lifts off easily. During reassembly, an audible click confirms positive engagement. The bayonet notch design allows the self-tailing arm to be locked in eight positions at 45-degree increments for optimal line routing.

Key Features:

  • Lightweight machined aluminum construction reduces weight without sacrificing strength
  • Power Ribs™ drum surface ensures controlled grip during tensioning and easing
  • Proven Andersen winch gearing configuration for reliable performance
  • Tool-free disassembly for quick configuration changes and easy servicing
  • Spring-loaded self-tailing jaws accept 6-10mm (1/4"-3/8") line
  • 18.3:1 power ratio with 2.7:1 gear ratio for efficient line handling
  • Low profile design with 42mm line entry height

Construction Materials:

  • Hard anodized aluminum drum, center stem, and self-tailing arm
  • Grade 316 stainless steel shaft and pawls for corrosion resistance
  • Grade 2205 duplex stainless steel axle pins
  • Aluminum bronze gears for durability and smooth operation
  • Glass-filled nylon self-tailer for strength and light weight
