Harken

<h3>About Harken: Performance Marine Hardware Since 1967</h3><p><strong>Harken</strong> is one of the most recognized names in performance marine hardware, with a legacy stretching back to 1967. <a href="/14853-harken">Harken</a> was founded in a 60-foot trailer by brothers Peter Harken and Olaf Harken, who set out to engineer better sailboat hardware than anything the market had to offer. Their early breakthrough — the plastic recirculating ball bearing block — redefined how sailors managed lines under load and launched a brand that would go on to dominate competitive sailing at the highest levels.</p><p>Headquartered in Pewaukee, Wisconsin, and with a major manufacturing facility in Limido Comasco, Italy, Harken operates as an employee-owned company with distribution spanning 48 countries. From club racing dinghies to grand prix offshore programs, Harken hardware has been aboard winning boats for decades — making its Olympic and America's Cup debuts in 1976 and 1977, respectively.</p><h3>A Full Range of Marine Hardware</h3><p>Harken's product lineup is broad by design. The company works hard to be the technological leader in sailboat blocks, deck hardware, winches, and hydraulics, as well as safety and rescue equipment and services. Their marine catalog includes small boat and big boat blocks, travelers and genoa leads, mainsail and headsail handling systems, winches, hydraulics, mooring solutions, and a robust line of spare parts and accessories.</p><p>At the core of it all are Harken's renowned <a href="/14853-harken-pulleys-blocks-200822">Pulleys &amp; Blocks</a> — the product category that started it all. Whether you're outfitting a high-tech racing dinghy or a bluewater cruising yacht, Harken blocks are engineered for high-load capacity, corrosion resistance, and the smoothest possible operation. The lineup spans sheave sizes from 16 mm all the way to 75 mm, with single, double, triple, fiddle, and soft-attach configurations to cover virtually every application on deck.</p><p>Beyond sailing, Harken also produces a dedicated line of sportfishing <a href="/14853-harken-pulleys-blocks-202394">Pulleys &amp; Blocks</a> engineered for the unique demands of offshore fishing. These compact, high-load pulleys are built for outrigger systems, dredge rigging, and heavy-duty line management — bringing the same patented bearing technology that excels on race courses to the rigors of the fishing cockpit.</p><h3>Why Sailors Trust Harken</h3><p>What sets Harken apart is a relentless commitment to engineering. Each product category is developed with input from top sailors, sailmakers, and boat designers — and the results speak for themselves on race courses worldwide. Harken hardware is a consistent fixture on America's Cup campaigns, Volvo Ocean Race fleets, Olympic classes, and everything in between. For cruisers, that race-proven performance translates into gear that is more reliable, longer-lasting, and more responsive than the alternatives.</p><ul><li>Employee-owned company with decades of marine engineering expertise</li><li>Manufacturing in the USA and Italy, with global distribution in 48 countries</li><li>Patented bearing systems engineered for high loads and minimal friction</li><li>Product lines covering everything from small dinghies to superyachts</li><li>Trusted at the Olympic Games and America's Cup since the 1970s</li></ul>

Product Details

The Harken 20STA is a single-speed, self-tailing Radial aluminum winch engineered for sailors who demand lightweight performance without sacrificing strength or holding power. Part of Harken's proven Radial winch line, the 20STA is an ideal choice for jib sheets, halyards, and control lines on daysailers and small cruising sailboats.

The Radial drum features a precision-engineered gripping surface with diagonal ribs specifically shaped for this winch size and drum material. Unlike abrasive texturing found on lesser winches, the rib design maximizes line grip while significantly reducing wear on rope. When easing a line, the rib angle prevents the line from riding up the drum, eliminating overrides and delivering a smooth, controlled release.

The self-tailing mechanism allows a single crew member to trim or raise sails efficiently, freeing up hands for other tasks. The aluminum drum construction keeps overall weight to a minimum while the composite self-tailing jaws and skirt add additional weight savings without compromising durability.

Key Features:

  • Radial drum with size-specific diagonal rib gripping surface — maximizes hold, reduces line wear
  • Self-tailing jaws allow single-handed sail trimming
  • Aluminum drum for substantial weight savings
  • Composite roller bearings reduce friction under load — no lubrication required
  • Snap-fit bearing cage keeps bearings captive in Delrin® cage during drum removal for maintenance
  • Load-carrying gears and pins are 17-4PH stainless steel for long-term strength and corrosion resistance
  • Fully enclosed winch top — keeps fingers and clothing clear of moving parts
  • Snap-on/off base skirt for easy deck installation
  • Single-speed operation with Power Ratio of 19.20
