High-strength straps
. Stainless steel straps reinforce blocks and resist corrosion.

Strong and Compact. Harken low-friction Carbo AirBlocks are lightweight, strong, reliable and affordable. These are features all sailors look for when choosing sail controls and real breakthrough in block design. These Harken small, compact blocks have very high working loads for safe, easy trimming no matter how hard the wind blows.

Sideplates of high-strength engineering resin are UV stabilized to provide excellent protection against long-term exposure to salt water and sun. Harken carbo blocks are perfect for the small-diameter hard lines favored by racers.

Lightweight, strong design. Harken Carbo Blocks are 30% lighter with a 60% higher working load than Classic blocks. Open Air Block design eliminates unnecessary material and weight.

Long-lasting protection. Ball bearings, sheave and sideplates UV-stabilized with carbon-black additive for maximum protection.

Three-way cam-lock. Patented switch locks shackle in front or side positions, or lets block swivel to keep line from twisting.

Harken Carbo Ratchets allow sailors to hand-hold loaded lines and offer balance between holding power and controlled easing.

Nylon resin sideplates are densely packed with long-glass fibers for a compact block with a high strength-to-weight ratio. Machined aluminum sheaves are Hard Lube-anodized for strength and corrosion resistance. Eight facets hold line securely. Ball bearings, sheave, and sideplates are UV-stabilized with carbon black for maximum protection.

The Harken Carbo Ratchamatic is a load-sensing ratchet block that rolls freely in both directions under low loads and automatically engages the ratchet as loads increase. Shifting between ratchet and light-air modes is seamless. Unloaded main and jib sheets run out freely during mark roundings and asymmetrical spinnakers free instantly during jibes.

For the ultimate system, mount a Ratchamatic® on the boom above a cockpit-mounted switchable ratchet to allow the mainsheet to run freely in light air and to double holding power in heavy air.

Harken Midrange Hexaratchets
grip loaded sheets, yet allow sailors to ease and trim quickly and with complete control. A switch on the side engages and disengages the ratchet mechanism.

To help you trim and keep from getting overpowered on multihulled boats, Harken has designed the multiple sheaved solutions to help you get your sail in as needed. Pair up selections to create a purchase system with ratchets or camcleats as needed. Technical assistance is available to help you create a purchase system tailor fit for your multihull.

Equip your boat with the top roller bearing blocks from Harken to help you withstand the high loads and heavy pulls you are going to need to keep your big boat moving forward.

The entire line of Harken AirBlocks has been redesigned with a sleek new look. Their unique, performance-packed engineering remains exactly the same. These strong lightweight blocks feature free rolling, high-load torlon roller bearings for a high strength-to-weight ratio. Use them for sail controls that see lots of action: mainsheet, runner, halyard, and spinnaker systems.

Cruising ESP blocks compliment existing blocks in looks and function, but are simpler in design and construction. Sheaves feature sleeve bearings to handle high static loads and are ideal for halyards or limited purchase systems on cruising boats.

Harken's line of Stainless Steel Blocks reflect the traditional beauty of your yacht's classic lines. Stainless sideplates are mirror-polished for durability and unmatched esthetic. The ultralight composite bearing system rides on a heat treated stainless inner race to handle extremely high loads.

Harken Aluminum Megayacht Blocks The clean, crisp look of aluminum is perfect for performance-oriented yachts. Sideplates are constructed of hardcoat-annodized 6061-T6 aluminum for strength and corrosion resistance. The ultralight composite bearing system rides on heat-treated stainless steel inner race to handle extremely high loads.
