Prevent Halyard Wraps
December 2001 2/2.5 Carbon Furler 15
■ 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 dam-
age to the unit and the halyard. In severe cases, halyard wraps
may cause loss of the headstay.
To prevent wraps, the halyard must exert a slight pull to
the rear. This allows the foils to turn while the halyard
remains stationary.
■ PRevenT HALyARd WRAPS
WARNING: The sail must be fitted to foils before operation.
1 Halyard swivel should be within top 4" (100mm) of foil.
2 Halyard must pull slightly to rear (8 - 10°).
3 Halyard must be snug, but not too tight.
If a halyard wraps, do not force unit to turn. Attempt to open
sail by alternately furling and unfurling sail slightly.
If the sail can be unfurled, lower sail by releasing jib halyard.
Severe halyard wraps can only be cleared by going aloft and
freeing halyard.
If the sail will not furl or unfurl, it may be possible to remove
jib sheets and manually wrap/unwrap the sail around/from
the headstay.
Important: Testing at the dock does not indicate halyard angle
is correct. In wave action, halyard may wrap if lead angle is
not correct. The diverging 8-10° angle mentioned above is
critical.
8 - 10°
