Harken New Small Boat BlocksHarken
Harken has updated its patent-pending T2™ Blocks with double versions of the 18, 29, 40, and 57 mm sizes, giving sailors the ability to build an even greater array of systems. Harken T2 Doubles share the same styling and all-composite construction as other blocks in the line. The 29, 40, and 57 have no rivets, fasteners, metal parts, or shackles, making them some of the lightest blocks on the market.

Harken T2 Double Blocks have received rave reviews from Olympic and world-class sailors for their reliability and smooth operation. Single and double configurations can be tied, spliced, or lashed to almost anything. Double blocks feature composite line guides in the block head to prevent capsizing. Composite sheaves spin freely on Delrin® ball bearings with curved bearing races for low-friction rolling under high loads. All Harken T2 Blocks are lashed or spliced through the load-bearing center of the block, decreasing sideplate loads and providing extra security. Harken T2 Blocks range from 18 to 57 mm and are ideal for traveler controls, mainsheets, vangs, cascades, and other applications that require small and extremely lightweight blocks.

Racers can trim even more weight off their mast and boom with new Harken Carbo Pivoting Lead Blocks. These high-strength, glass-reinforced composite blocks are up to 25% lighter than the Classic version they replace. With maximum working loads up to 136 kg (300 lb), they're perfect for sheets and halyards on small boats and control lines on larger boats.

"I was psyched to install the new Carbo Pivoting Lead Blocks on my F-18," says product designer Graham Walker. "I use a 40 mm for the spin halyard and two 29s for the cunningham on my rotating mast. I was able to switch out to lighter blocks that have the same working load and same mounting hold pattern, and now I don't have to worry about corrosion between stainless bases and my aluminum mast."

Pivoting Lead Blocks allow free mast rotation while still allowing cleating and control from the cockpit. They're also ideal as boom-mounted mainsheet blocks for converting old systems where the skipper has to reach aft to trim the sheet.

Carbo Pivoting Lead Blocks feature the same hole spacing and rivet size as Classic Pivoting Lead Blocks for easy upgrades. An integrated reversible cam cleat allows you to swap the cleating or uncleating direction—up or down on mastbase configurations and fore or aft on horizontal installations. The high-load ball bearings, sheave, and sideplates are all corrosion proof and UV-stabilized for maximum weather resistance. Carbo Pivoting Lead Blocks are available in 29 mm and 40 mm sizes with aluminum or Carbo Cam® Cleats.
