D1 - Systems (installation below deck)

Scope of application

This type of reefing system with waterproof deck passage is used on classic yachts to preserve the look with modern technology. In competition sailing too, the installation of a jib furling system below deck makes it possible to bend-on the sail‘s tack close to the deck. Thanks to the bilateral angular mobility of the waterproof deck passage, misalignment is compensated. As well construction clearances below deck and different headstay angles caused by differing mast rakes or slack in the headstay can be compensated. Jib reefing systems make it possible to reduce the sail area continuously as long as the sail is suitable for that by weight of the cloth and its construction. Existing sails with jib hanks can be made reefable by sewing on a luff tape, larger sails with a deep cut (profile) should be made reefable by doubling up near the luff. The length of the headstay and therefore the mast rake can be adjusted via the telescopic coupling set, regardless of the foil length. The final headstay tension can be adjusted over the backstay or running backstays. Due to the elimination of the hanks, furling sails can be set and recovered very quickly while the halyard remains always connected to the sliding halyard swivel.

Benefits

• Safe and fast furling performed from the cockpit
• Easy and fast sail changes (no hanking-on and hanking-off)
• Lowest possible attachment points for the sail‘s tack
• Improved airflow (no slack in the luff as with hanks)
• Compensation for misalignment
• Maintaining the appearance of classic yachts
