D1 - Systems (installation on deck)

Scope of application

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. An aluminum foil headstay is installed around the headstay cable. The luff is inserted into its groove and is hoisted with the sliding halyard swivel. For easier shipping, the foil elements are 2-3 m long and can be replaced in case of damage. 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 via the backstay or running backstays. Due to the elimination of the hanks, furling sails can be set and recovered very quickly while the halyard always remains connected to the sliding halyard swivel.

Benefits

• Safe and fast reefing performed from the cockpit
• Easy and fast sail changes (no hanking-on and hanking-off)
• Better air flow (no slack in the luff like with hanks)
• Lower luff tension (relieving the jib halyard as compared to systems with hanks)
