Designed specifically to handle the demanding, fast-paced adjustments required in competitive dinghy racing, this block brings Harken’s top-tier Zircon ceramic bearing technology to a highly specialised, problem-solving shape.\u003c\/p\u003e\n\u003cp\u003eConventional double blocks have a frustrating tendency to tip, twist, or completely tangle under the high-tension loads of an ILCA's vang, cunningham, or outhaul. The 1251 Twisted Fiddle is purpose-built to solve this. Its uniquely slim, twisted profile is designed to slide effortlessly along the purchase system it inhabits, remaining perfectly upright and aligned even under dynamic loads.\u003c\/p\u003e\n\u003cp\u003eFurthermore, the stepped \"fiddle\" design is a superior choice over standard double blocks for these applications. Because the lines in your purchase systems often move in an uneven sequence around the sheaves, the fiddle configuration keeps the lines cleanly separated and routing smoothly around the dual 29 mm and 18 mm Zircon sheaves. The result? Crisp, immediate, and tangle-free sail adjustments right when you need them most.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eTwisted Profile: Keeps the block perfectly upright and aligned, eliminating the tipping and tangling common with standard double blocks.\u003c\/li\u003e\n\u003cli\u003eFiddle Configuration: Ideal for purchase systems where lines move in uneven sequences, providing clean routing and separation.\u003c\/li\u003e\n\u003cli\u003eZircon Bearings: Delivers the ultimate low-friction performance for lightning-fast, highly responsive sail adjustments.\u003c\/li\u003e\n\u003cli\u003eSlim Design: Slides cleanly and easily within complex ILCA purchase systems without snagging.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eMetric\u003c\/th\u003e\n\u003cth\u003eImperial\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSheave Diameter\u003c\/td\u003e\n\u003ctd\u003e29 mm\u003c\/td\u003e\n\u003ctd\u003e29\/32 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Line Diameter\u003c\/td\u003e\n\u003ctd\u003e5 mm\u003c\/td\u003e\n\u003ctd\u003e3\/16 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Working Load\u003c\/td\u003e\n\u003ctd\u003e91 kg\u003c\/td\u003e\n\u003ctd\u003e2000 lb*\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cem\u003e*(Note: Ensure working load limits align with your specific rigging requirements).\u003c\/em\u003e\u003c\/p\u003e","brand":"ILCA","offers":[{"title":"Default Title","offer_id":52605524377941,"sku":"IL-ILC5014","price":78.08,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0898\/9068\/5269\/files\/hk-1251.webp?v=1778016452","url":"https:\/\/sailboats.co.uk\/products\/harken-29-18mm-zircon-twisted-fiddle-blocks-for-ilca-laser","provider":"Sailboats.co.uk","version":"1.0","type":"link"}
