<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.

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.
