Adjustments Pendant/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.
TIP: Pendants are used at the head of the sail. Short
pendants may be added at the tack to improve visibility
under the genoa, but remember that visibility is already
improved by shackling to the tack swivel. Tack pendants
increase heeling moment by raising the sailplan. You may
install pendants at both the head and tack of the sail.
■ HALYARD RESTRAINER
To prevent wraps, jib halyard must pull slightly to rear. On
some boats halyard sheaves are located too close to headstay
and a halyard restrainer must be used.
Use halyard restrainers only when required by masthead
geometry. Restrainers tend to limit sail luff length and may
cause problems if not properly installed.
Mount restrainer as high as possible on face of mast.
Position restrainer so foils will not hit it when under load.
The restrainer should deflect halyard 8 - 10°.
8 - 10°
CAUTION!: If halyard angle is more than 10°, you
may experience difficulty in tensioning sail luff,
friction in furling and possible damage to foils.
■ INSTALL A PENDANT
1 Raise the sail, but do not attach tack shackle.
2 Position the halyard swivel correctly near the top of
the headstay and secure the halyard.
3 Secure a piece of rope to the sail tack. Lead the line
through the tack shackle on the furling drum and
tension the sail.
4 Measure the distance from the tack shackle to the
sail tack and have a pendant of this length permanently
attached to the head of the sail.
5 Repeat this procedure for every jib.
To decrease deflection angles, shorten sail luff.
