12. oning Halyard Wrap HALYARD WRAPS The most serious problem with furling systems occurs when the jib halyard wraps around the headstay foil Halyard wraps will prevent furling or unfurling and may cause serious damage to the unit and the halyard In severe cases halyard wraps may cause headstay loss To prevent wraps the halyard must exert a slight pull to the rear his allows the foils to turn while the halyard remains stationary PREVENT WRAPS WARNING The sail must be fitted to the foils before operation 1 Halyard swivel should be within the top 4 100 mmy of the foil 2 Halyard must pull slightly to the rear 8 10 3 Halyard must be snug but not too tight If a halyard wraps do not force the unit to turn Attempt to open the sail by alternately furling in and out slightly If the sail can be unfurled lower the sail by releasing the jib halyard Severe halyard wraps can only be cleared by going aloft and freeing the halyard If the sail will not furl or unfurl it may be possible to remove the jib sheets and manually wrap the sail around the headstay Remember Testing at the dock does not indicate the halyard angle is correct In wave action the halyard may wrap if the lead angle is not correct The 8 107 diverging angle mentioned above is critical TIP With the sail raised walk away from the boat and look at the masthead with binoculars Use the halyard swivel as a measurement reference 4 100 m
