Harken C7475 MKIII Jib Reefing & Furling - Manual (Page 11)

■ PENDANTS
If your sail is not long enough to position the halyard swivel prop-
erly, you must add a pendant to the sail. Pendants should be plas-
tic 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.
■
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.
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
sail plan. You may install pendants at both the head
and tack of the sail.
ADJUSTMENTS Pendants/Halyard Restrainer
■ HALYARD RESTRAINER
To prevent wraps, the jib halyard must pull slightly to the
rear. On some boats the halyard sheaves are located too
close to the headstay and a halyard restrainer must be used.
Use halyard restrainers only when required by the masthead
geometry. Restrainers tend to limit sail luff length and may
cause problems if not properly installed.
Mount the restrainer as high as possible on the face of the
mast. Position the restrainer so the foils will not hit it when
under load.
The restrainer should deflect the halyard 8 - 10°. If the angle
is more than 10°, you may experience difficulty in tensioning
the sail luff, friction in furling and possible damage to the foils.
To decrease deflection angles, shorten the luff of the sail.
■ HALYARD TENSION
The jib halyard should be firm, but not too tight.
TIP: Boats used in charter service should consider using a
halyard restrainer, regardless of masthead geometry.
TIP: The luff foil system supports the sail along its entire
length so halyard tension is required only to shape
sails, not to support them.
Use only enough halyard tension to remove some
wrinkles along the luff. Do not tension the halyard
enough to cause vertical wrinkles in the luff.
Use halyard tension to adjust draft position of the sail
to suit sailing conditions. Your halyard should be firm
but not tight. If in doubt, release halyard tension.
To protect the sail, ease the halyard when the boat
is not in use.
