Harken, Inc. is a leading manufacturer and marketer of quality marine and sailboat hardware and accessories. Buy Harken hardware such as fiddle blocks, winches, travelers, mainsail & headsail systems, and aÂ full range of hydraulic products and services for your boat.
Harken offers three categories of Big Boat blocks. AirBlocksÂ® are designed for offshore boats where weight and performance are critical. They are lightweight, UV protected and easily maintained.
Megayacht ULC blocks feature mirror-finished stainless steel or hardcoat-anodized aluminum sideplates and our ultralight composite bearing system (ULC) to handle extremely high loads.
ESP, or Elegant Simple Products, is a line of hardware that complements our blocks in looks and function, but is simpler in design and construction.
Harken Carbo Ratchamatic Block
The Harken Carbo RatchamaticÂ® 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.
Ratchet engagement may be adjusted to a higher or lower load according to strength and sailing style. The Harken RatchamaticÂ® cheek block mounts on either port or starboard. The holding power of the 57 mm is as high as 10:1.
For the ultimate system, mount a Harken RatchamaticÂ® 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.
Use for: Main/Jib Sheets and Asymmetric spinnakers.
Harken Black Magic Spriddle Blocks
Harken Black MagicÂ® AirBlocksÂ® feature TorlonÂ® roller bearings for strength and reduced wear. The unique center cage separates rollers for less friction. Sideload ball bearings are protected by sculpted aluminum sideplates. Dissimilar metals are isolated to minimize corrosion. Low-load blocks use DelrinÂ® rollers and type 316 stainless steel shackles.
Like all AirBlocksÂ®, the three-way head swivels/locks in front/side positions. Blocks are easily disassembled with a single Allen wrench. Use straphead blocks with LOUPSâ¢ or straps aligned fore/aft or side to side.
Use for: Sheets, Halyards, Running backstays and Control lines.
