HARKEN Code Zero Furling

Originally built for Volvo 60s, Code Zero furlers are used with free-flying asymmetrical headsails and staysails. Suitable for boats up to 125 (38 m), they tame Code Zero sails, screechers, Gennakers® and staysails.

The eight-faceted sheave-drive grips line aggressively to furl these huge sails with minimal line. Its large diameter makes furling smooth and easy. The 3126, 3127, 3128 and 3115 Code Zero's spring-loaded arms hold line captive in the sheave. Arms open to remove the line for quick unfurling, or to strike the furler. A built-in stripper safely guides line out of the furler. The lower unit incorporates a quick sail disconnect by pushing a spring-loaded button.

Compact hardened steel roller thrust bearings handle extremely high luff loads. Furler heights are kept to a minimum, so luff lengths can be at maximum length.

Since furling a Code Zero sail requires very high luff tension, a 2:1 adapter is available. This fits either the upper or the lower unit, but installation on the upper is advised to prevent halyard twisting. A snap shackle adapter allows quick disconnect.

To handle torsional load, we recommend a dual luff cord system. This system uses thimbles to loop the cords around the tack and head of the sail. Talk to your sailmaker. Code Zero furlers are not for reefing.

  • Code Zero 00: 20'-30' (6-9m)
  • Code Zero 0: 25'-40' (8-12m)
