C1 & C2 Systems (installation below deck)

Scope of application

This type of furling system with compact / cost-effective deck-passage is used on sporty dinghies / yachts when the furling mechanism should disappear below deck in order to reach a low attachement point for the sail tack. The deck-passage DK has to be mounted in the direction of the headstay and is not completely watertight. (Mutually independent angular mobility above and below deck as well as complete watertightness are provided by deck passage type DD)

The jib furling systems with halyard swivel for cable headstays are suitable for complete furling of hank-on sails. A Reefing is not possible because the cable headstay is not suitable as a reefing core (the sail is constricted, twisted and damaged).

Beyond headstay lengths of 8 meters we recommend using a halyard swivel with coupling and a coupling terminal. In the top position, the halyard swivel engages into the longitudinal groove of the coupling terminal. Thus the sail head is rotated parallel to the tack and an blowing out of the furled sail in the head area is prevented during stronger wind gusts.

The length of the luff must be adjusted so that the halyard swivel is positioned at about the middle of the coupling terminal. Sails with a shorter luff must be extended with a cable extension.

Benefits

• Compact and cost-effective
• Continued use of hank-on sails
• Lowest attachement point for the sail tack
• Adjustable headstay length from below deck while sailing
• Compact / unobtrusive and robust stainless-steel design
• Drum and endless rope furler available 
• Continued use of existing jib halyard (hoisting operation from the cockpit)
• Safe sail changes (during a sail change, the halyard always stays connected to the headstay by the halyard swivel)
