Barton Marine Pulleys & Blocks
Barton Marine Pulleys & Blocks: Engineered for the Sea
Few names carry as much weight in sailing hardware as Barton Marine. Founded in 1948 in Whitstable, England — a region steeped in shipwright tradition — the company built its reputation on a simple idea: sailing blocks should be lighter, stronger, and more reliable than anything that had come before. That commitment to engineering excellence is nowhere more evident than in Barton Marine's extensive range of pulleys and blocks.
A Legacy Built on Block Innovation
Barton's story with blocks begins at its very founding. The company was among the first manufacturers to use Tufnol — a fabric-based laminated plastic — alongside stainless steel to produce yachting blocks that were dramatically lighter and stronger than their wooden predecessors. Later, Barton became the first to apply injected plastic moulding to its entire block range, cementing its status as a pioneer in the field. That spirit of innovation has never stopped, earning Barton multiple block test victories in respected publications such as Die Yacht and PBO Magazine.
The Block Range: Something for Every Boat
Barton Marine's pulley and block lineup spans a wide size range — from the featherweight Size 0 with 20mm sheaves, tipping the scales at just 13 grams and ideal for dinghies, day boats, and lead blocks on larger yachts, all the way up to the heavy-duty Size 7 high-load cruising blocks engineered for superior strength under serious loads. Each size tier is available in both plain bearing and ball bearing sheave configurations, allowing sailors to balance cost, weight, and performance for their specific application.
Across the range, construction quality is consistent and deliberate. The high-load cruising blocks feature high-grade glass fibre nylon reinforced moulded side plates with an internal 316 stainless steel frame that is through-bolted and riveted for exceptional strength and durability. All load-carrying components use marine-grade 316 stainless steel, while Ertalyte sheaves minimize friction and maximize wear resistance — critical qualities for lines that cycle thousands of times over a sailing season.
Designed for Cruisers and Racers Alike
Barton's mid-range blocks — such as the popular Size 4 and Size 5 lines with 54mm sheaves — are engineered specifically for larger cruising and racing yachts and are fully compatible with Barton's own ball-bearing mainsheet traveller system, making it straightforward to build out a cohesive, matched deck hardware setup. For the smallest craft and finest lines, the Size 0 and Size 1 blocks offer an internal steel frame for durability in a modern, lightweight form factor suitable for rope up to 8mm.
Barton also offers UV-resistant PVC block covers for their Size 2, 3, and 5 blocks — a practical detail that protects sheave assemblies from sun degradation during prolonged offshore passages or when a boat is laid up between seasons.
