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>

Very good experience

I sent in a return request haven't heard anything back would like to return this item

Great service quick delivery

As always great experience. I have ordered from this place in the past and have never had a bad experience. Much appreciation to this company and the people who work there. Thanks again.

I didn't use boatplicity.com for customer assistance, but the "contact us" section. the unit isn't, hasn't nor was it working as designed. air blows, but it isn't even close to warm air.

I just never do top scores

It was what I needed, and worked perfectly, great price
