{"title":"Ratchet Blocks","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eA good ratchet block is one of the simplest upgrades you can make to a dinghy mainsheet or control line, taking the strain off your hands so you can hold the sheet through a gust without burning your fingers. The ratchet mechanism lets the line run freely when you ease, then grips firmly when loaded, giving you up to ten times more holding power. We stock ratchet blocks from leading dinghy hardware brands including Harken, Allen and Ronstan, with sizes and bearing types to suit everything from club boats to performance racers.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eRatchet blocks suit anyone who sails a boat with meaningful mainsheet or kite loads, from weekend club sailors to competitive racers. The benefit is straightforward: less effort holding the sheet, more concentration on boat speed and tactics. Some blocks ratchet constantly, while others switch on and off so you can choose free running or grip depending on conditions and point of sail.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eWhen choosing a ratchet block, match the sheave diameter to your line size and check the maximum working load against your rig. Decide whether you want a fixed ratchet, a switchable on\/off version, or an auto-switching block. Bearing choice matters too: ball bearings run smoother under light loads, while roller bearings cope better with heavy sustained loads.\u003c\/p\u003e","products":[{"product_id":"harken-57mm-carbo-ratchet-block","title":"Harken 57mm Carbo Ratchet Block - 2135","description":"\u003ch2\u003e57mm Harken Carbo Ratchet Block with Swivel - 2135\u003c\/h2\u003e \u003cp\u003e57mm Harken Carbo Ratchet blocks allow you to hold your ropes in your hand and offer balance between holding power and controlled easing.\u003c\/p\u003e \u003cp\u003eThis 57mm ratchet block has an on\/off switch so the ratchet can quickly be turned off when not needed.

Hinged construction allows for various lead angles. Ratchamatic block versions roll freely in both directions under low loads and automatically engage a ratchet mechanism as loads increase, giving sailors a holding power of up to 15:1. The ratchet engagement can easily be adjusted to a higher or lower load depending on the sailor’s strength, sailing style and system usage.\u003c\/p\u003e \u003cp\u003e\u003ci\u003ePlease note: This product comes with a lead time expected to be up to 10 working days.\u003c\/i\u003e\u003c\/p\u003e \u003ch3\u003eSpecifications\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eSheave Ø - 57mm\u003c\/li\u003e \u003cli\u003eLength - 110mm\u003c\/li\u003e \u003cli\u003eWidth - 50mm\u003c\/li\u003e \u003cli\u003eHeight - 66mm\u003c\/li\u003e \u003cli\u003eWeight - 156g\u003c\/li\u003e \u003cli\u003eMaximum line Ø - 10mm\u003c\/li\u003e \u003cli\u003eMaximum working load - 227kg\u003c\/li\u003e \u003cli\u003eBreaking load - 554kg\u003c\/li\u003e \u003c\/ul\u003e","brand":"Harken","offers":[{"title":"Default Title","offer_id":39457292025929,"sku":"2144","price":290.39,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0138\/5899\/6288\/files\/4e3cad79-3086-4919-9f4d-a3ed2aa5e4a1_a50d2ab3-8074-4355-8bc8-51ba50a4245a.jpg?v=1769581191"},{"product_id":"selden-60mm-manual-ratchet-single-block-1","title":"Selden 60mm Manual Ratchet Single Block","description":"\u003ch2\u003eSelden 60mm Manual Ratchet Block\u003c\/h2\u003e \u003cp\u003eSelden 60mm manual ratchet pulley block with delrin ball bearings and a carbon fibre reinforced polyetherimide sheave.\u003c\/p\u003e \u003cp\u003eThere is a switch on the side of this ratchet block which allows the ratchet to be turned on and off.\u003c\/p\u003e \u003ch3\u003eSpecifications\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eSafe Working Load - 250kgs\u003c\/li\u003e \u003cli\u003eBreaking Load - 500kgs\u003c\/li\u003e \u003cli\u003eWeight - 121grams\u003c\/li\u003e \u003cli\u003eMax Rope Diameter - 10mm\u003c\/li\u003e \u003c\/ul\u003e","brand":"Selden","offers":[{"title":"Default Title","offer_id":46485187330367,"sku":"406-350-01R","price":89.99,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0138\/5899\/6288\/files\/61b2a54c-13ad-4375-803c-b50249e966fe_7a75b6d1-d6df-4eeb-b030-32a79390ecf0.jpg?v=1738923381"},{"product_id":"allen-60mm-pro-ratchet","title":"Allen 60mm Pro Ratchet","description":"\u003ch2\u003eAllen 60mm Pro Ratchet Block\u003c\/h2\u003e \u003cp\u003eThis 60mm ratchet block comes with a shackle on top and has an on\/off switch so you can quickly and easily turn the ratchet on and off.
