Manufacturer

Harken

<h3>About Harken: Performance Marine Hardware Since 1967</h3><p>Harken, Inc. is an international manufacturer specializing in performance sailing hardware, headquartered in Pewaukee, Wisconsin. The company was founded in 1967 by brothers Peter Harken and Olaf Harken. What began as a scrappy operation in a 60-foot trailer has grown into one of the most recognized names in marine hardware worldwide.</p><p>Starting with the invention of the plastic recirculating ball bearing block and the development of Olympic sailboats, Harken is now the brand of choice for most leading sailing teams, designers, and builders. Harken hardware has been a dominant force in the racing segment for many years, making its Olympic and America's Cup debuts in 1976 and 1977, respectively.</p><p>Harken works hard to be the technological leader in sailboat blocks, deck hardware, winches, and hydraulics, as well as safety and rescue equipment and services. The company is employee-owned and has factories in Pewaukee, WI, USA and Limido Comasco, Italy, with distribution in 48 countries and group offices in 9 countries.</p><h3>Harken Winches &amp; Winch Handles</h3><p>At the heart of any serious sailboat's control system is the winch, and Harken's reputation here is second to none. Harken winches — including self-tailing and electric options — are known for their power, durability, and smooth operation. Harken's innovative Radial Line winches deliver a perfect balance of power, grip, and control, designed for smooth line handling under load. Their compact design and durable build make them ideal for both new installations and upgrades to existing systems. Browse our full selection of <a href="/14853-harken-winches-winch-handles-201186">Harken Winches &amp; Winch Handles</a> to find the right fit for your boat.</p><h3>Harken Cleats</h3><p>Line management is critical on any vessel, and Harken's cleats are legendary among sailors for their engineering precision. Multiple rows of high-load ball bearings and a precise V-shape reduce friction, allowing Harken cam cleats to activate with the snap of a wrist. No need for draw-through cleating: a downward flick snaps the sheet into the cam and stays exactly where you put it — flick up and the cleat releases instantly, even under high loads. Harken cleats are the only cleats that engage under maximum line tension. Explore our range of <a href="/14853-harken-cleats-200268">Harken Cleats</a> for options suited to racers and cruisers alike.</p><h3>Harken Blocks</h3><p>A company that started with only making ball bearing blocks turned into a well-known brand of blocks, travelers, deck hardware, winches, and more. Today, Harken's block lineup spans everything from lightweight dinghy hardware to mega-yacht systems. Harken blocks are famous for their ball-bearing technology, which ensures sheaves spin freely even under extreme tension. Harken sailboat components, including blocks, are designed for use aboard any boat from dinghies to mega-yachts. Discover the full range of Harken Blocks for every point of sail and every size of boat.</p><h3>Harken Non-Skid Tape &amp; Pads</h3><p>Safety aboard starts with secure footing, and Harken addresses this with their Marine Grip non-skid solutions. The cost-effective, non-skid grip tape is easy to install and clean, remains in place without peeling, sheds water and grime, and won't burn feet. Testing proves Marine Grip performs at least 40% more effectively than competitive products or wax. Shop Harken Non-Skid Tape &amp; Pads to keep your crew sure-footed in all conditions.</p><h3>Why Sailors Trust Harken</h3><p>Harken is an industry leader and routinely dominates major sailing events worldwide, including the America's Cup, the Volvo Ocean Race, and the Olympics. Harken Marine products are high strength with minimal weight and size, making them a great choice for high-load management systems. From weekend cruisers to professional racing teams, Harken's commitment to low friction and maximum strength has made it the go-to hardware brand for sailors around the globe.</p>

Product Details

The Harken 20STC is a Size 20 Radial one-speed, chrome self-tailing winch built for sailors who demand both elegance and reliable performance. The mirror-polished chrome drum pairs with a black composite base and top, delivering a refined look on any yacht's deck without sacrificing the proven pulling power of Harken's Radial gearing system.

The Radial drum gripping surface is precision-engineered for the Size 20 chrome drum specifically. Because chrome is more slippery than aluminum, the diagonal ribs are spaced closer together to maximize friction and holding power while still greatly reducing line wear compared to abrasive surfaces. When easing under load, the patented rib angle drives line wraps downward, preventing overrides and providing smooth, controlled release.

The self-tailing mechanism allows a single crew member to efficiently trim or raise sails hands-free, with spring-loaded composite jaws that adjust under line pressure to accept a range of line sizes. The fully covered winch top keeps fingers and clothing clear of moving parts.

Key Features:

  • Mirror-polished chrome drum with size-specific diagonal rib pattern for maximum grip and reduced line wear
  • Single-speed operation with a gear ratio of 2.76:1 and a power ratio of 19.20
  • High-strength composite self-tailing jaws and skirt — lightweight and corrosion-resistant
  • Composite roller bearings reduce friction under load and require no lubrication
  • Load-carrying gears and pins are 17-4PH stainless steel for long-term strength and corrosion resistance
  • Snap-fit roller bearing design keeps bearings captive in a Delrin® cage during drum removal for maintenance
  • Snap-on/off base skirt enables easy one-person installation without removing the drum
  • Sealed top lifts out as a single unit for quick, mistake-free seasonal maintenance
  • Accepts line from 1/4 in. (6 mm) minimum to 1/2 in. (12 mm) maximum

Specifications:

  • Drum Diameter: 2-7/8 in. (73 mm)
  • Base Diameter: 5-3/8 in. (137 mm)
  • Height: 5-13/16 in. (148 mm)
  • Line Entry Height: 2-3/8 in. (61 mm)
  • Fastener Circle: 4-3/8 in. (110 mm)
  • Fasteners: 5 × 1/4 in.
  • Gear Ratio: 2.76 | Power Ratio: 19.20
  • Weight: 7.5 lbs.

The Harken 20STC is a top choice for small boat and yacht owners seeking a compact, low-maintenance, self-tailing winch that combines classic chrome aesthetics with Harken's industry-leading Radial winch engineering.
