Barton Marine

<h3>Barton Marine: Nearly 80 Years of Sailing Hardware Innovation</h3><p><strong>Barton Marine</strong> has been one of the world's most respected names in sailing hardware ever since shipwright Ron Barton founded the company in Whitstable, Kent, England in 1948. What started as a small boatbuilding operation grew into a globally recognized manufacturer, driven by a willingness to pioneer new materials and engineering techniques long before competitors caught on.</p><p>From the very beginning, Barton stood apart by embracing innovation. Ron Barton was among the first manufacturers to recognize the potential of Tufnol — a fabric-based laminated plastic — and stainless steel for crafting yachting blocks that were both lighter and stronger than traditional wooden alternatives. When GRP boats democratized sailing in the 1960s, Barton doubled down on progress, becoming the first marine company to adopt plastic injection moulding across its entire block range. The result was a generation of hardware that was more affordable, more reliable, and more performance-oriented than anything previously available.</p><p>Today, <a href="/11485-barton-marine">Barton Marine</a> produces over 1,000 different hardware products designed for sailboats of all sizes — from nimble dinghies and keelboats to cruising yachts up to 16 meters in length. All products are manufactured at the company's purpose-built factory in Whitstable, with a skilled local workforce that has long passed its craftsmanship traditions down through generations of employees.</p><h3>A Comprehensive Range Built for Sailors</h3><p>Barton's catalog spans nearly every aspect of deck hardware. Their blocks — available in materials ranging from carbon fibre and anodized aluminum to classic Tufnol — are engineered for low-friction line handling under demanding loads, and have won multiple industry &quot;block test&quot; awards from respected marine publications. Traveller systems, genoa cars, rope clutches, deck organisers, and reefing kits round out a range that covers virtually every sail-handling need.</p><p>One of the most recognized product categories in the Barton lineup is their cleats, which are manufactured using high-quality materials like nylon composites and Tufnol to deliver a low-profile, saltwater-resistant design that stands up to the harshest marine environments. Whether you need sliding cleats for dinghy track systems or robust horn cleats for larger yachts, Barton's extensive <a href="/11485-barton-marine-cleats-200268">cleat range</a> offers a solution for every application.</p><p>Barton also manufactures a well-regarded range of composite winches — lightweight, virtually self-lubricating, and corrosion-resistant alternatives to conventional steel winches — alongside winch handles, snubbing winches, and the clever Wincher adapter that converts a standard winch into a self-tailing unit.</p><h3>Why Sailors Trust Barton Marine</h3><p>The longevity of Barton Marine's reputation rests on a straightforward principle: build hardware that simply doesn't fail. Sailors who race offshore events like the Fastnet Race, as well as recreational cruisers circumnavigating the globe, return to Barton because the hardware is dependable when it matters most. That philosophy, paired with continuous product development — including the innovative Boomstrut, carbon fibre tiller extensions, and the 2026 New Generation block series — ensures that Barton Marine remains at the cutting edge of sailing deck hardware well into its eighth decade.</p>

Product Details

The Barton Marine Size 7 Single Plain Bearing Stand-Up Block is a high-performance cruising block designed for larger sailing yachts where reliability and strength are paramount. This rugged block features a precision-molded acetal sheave running on a large diameter brass bearing, ensuring smooth, free-running operation even under maximum loads.

Key Features:

  • Precision molded acetal sheave with large diameter brass bearing for reliable performance
  • High-quality injection molded side plates with through-bolted and riveted construction
  • All load-carrying components manufactured from 316-grade stainless steel for corrosion resistance
  • Stand-up block design ideal for use on larger cruising and racing yachts
  • Safe working load of 2,750 lbs (1,250 kg) with break load of 5,500 lbs (2,500 kg)

Specifications:

  • Overall Length: 6-3/8 inches (162 mm)
  • Sheave Size: 2-3/4 inches x 3/4 inch (70 mm x 20 mm)
  • Maximum Rope Diameter: 9/16 inch (14 mm)
  • Weight: 444 grams
  • Safe Working Load (SWL): 2,750 lbs (1,250 kg)
  • Break Load: 5,500 lbs (2,500 kg)

Important Note: Stated break and safe working loads assume all sheaves are evenly loaded, as in a purchase tackle. Uneven loading or loading of a single sheave in a multi-sheave block will reduce the rated strength.
