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.
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.
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.
8 - 10°
HALYARD TENSION
The jib halyard should be firm, but not too tight.
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.
TIP: Boats used in charter service should consider using a
halyard restrainer, regardless of masthead geometry.
