B1 - Furling systems for hank-on sails

Wire headstay / halyard in mast / installation above deck

Scope of application

The jib furling system with tackle is characterized by its simple design. The cable or dyneema halyard is running through a block in the lower (turning) part of the forestay-swivel and is tightened above the jib furler with a tackle. These systems don´t need a halyard swivel, which is only required when the halyard has to be decoupled from the turning headstay.

The sail head is rotated parallel to the tack and a blowing out of the furled sail in the head area is prevented during stronger wind gusts. The same effect is reached by the halyard swivel with coupling (see C2-Systems).

The separate halyard (parallel to the headstay) is operated from the foredeck. When changing the sail, the cable halyard must be extended with a safety line, so it does not run out. Sails with shorter luff must be extended with a cable lead to make sure the tackle reaches far enough (for example when using a storm jib).This type of furling system is most commonly used with headsails which are rarely changed.


  • Continued use of hank-on sails
  • Easy installation and handling
  • Low attachement point for the sail tack
  • Compact and unobtrusive design
  • Drum and endless rope furler available
  • Simple upgrading to a jib furling system with halyard swivel for cable headstays (Cx-Systems)
