- Page 18 Commissioning 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.
- Page 19 Commissioning Halyard Restrainer PENDANTS If your sail is not long enough to position the halyard swivel properly, you must add a pendant to the sail. Pendants should be plastic coated wire permanently attached to the sail so the height will be correct. Adjustable length pendants are not acceptable as they might not be adjusted correctly during a sail change.
