The new Carbo Twing block (Harken part number 2699) features a spring-loaded, top-opening mechanism so you can rig it quickly whenever the breeze or sea state indicates an adjustment in leech twist would move the knot meter.

Low-friction Carbo Air blocks are lightweight, strong, reliable—and affordable. Companions to our popular Harken Big Boat blocks, these small, compact blocks have very high working loads for safe, easy trimming.

What Makes it Special?

There has been an abundance of innovation happening with foredeck sails these days. From Code Zeros to top down furlers; the spectrum of new ideas is dazzling. With the surge in options comes the need for more leech profiles to match and more options for creative trimmers to perfect their rig.

Harken at the front, has developed new opening Twing blocks engineered to streamline the rigging and de-rigging process of foredeck sails. The quick one-handed, spring loaded design makes it easy to make adjustments when the conditions demand quick reactions. Twing blocks are designed to allow for easy 2:1 rigging for smoother up/down adjustments under load. Additionally, they can be attached using a fixed loop to a padeye or loop spliced and run directly to a fairlead and cleat.
