    Category Description


    Harken, Inc. is a leading manufacturer and marketer of quality marine and sailboat hardware and accessories. Buy Harken hardware at Mauri Pro Sailing Store such as ratchet blocks, winches, travelers, mainsail & headsail systems, and a full range of hydraulic products and services for your boat.

    Harken ratchet blocks have really impressive features, some are listed below:

    • They hold part of the sheet’s load, let you trim and ease with complete control, and enable higher trimming speeds
    • Easier to hand-hold higher loads by only allowing the sheave to turn in the trimming direction
    • Faceted sheave grips the line to reduce fatigue and give you more control
    • Faster trimming possible because you don’t have to hold the full force of the sheet while shifting your grip

    Options include ratchet blocks with beckets, adjustable cams, multiple sheaves, adjustable automatic load-sensing mechanisms, and footblock and fiddle configurations. Harken offers ratchet blocks in sizes between 40 and 75 mm (1 9/16"–3"). Ratchet blocks are great for any system that is normally adjusted by hand, including mainsheets, jib sheets, spinnakers, vangs, and backstays on everything from dinghies to large keelboats. In addition to increasing the loads you can manage without a winch, they reduce shock loading on your hands and your equipment—for example, a ratchet block can stop an unanticipated gust from yanking the line through your hands or from putting too much load on your cam cleats. Some dinghies and sportboats even use two Ratchamatics® in series for turns less than 90 degrees per ratchet block.

    We are fully committed to be your Harken Ratchet Block specialist not only providing the sailing community with a comprehensive and easy to use web site but with all the appropriate technical information that you might need to select your sailboat hardware and equipment.
