Harken Big Boat BlocksHarken

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.
