Harken 944 Instruction Sheet

Strictly follow all instructions to avoid an accident, damage
to your vessel, personal injury or death. See www.harken.com/
manuals for additional safety information.
To be used if angle between halyard and headstay is less than 7°. This
is common on masts where halyard sheave is very close to headstay.
If halyard angle is greater than 7° and halyard is still wrapping, a halyard
restrainer may not be necessary. Halyard swivel must be near top of
foils and headstay must be tight. This will prevent halyard wraps in
most cases. Consult furling instruction manual.

1. Hoist tallest sail that will be used.
If mast is down, angle headstay out to stemhead
chainplate ("J" dimension). Measure luff length of
tallest sail and position restrainer as directed below.
Installations aloft should be performed by rigging
professionals only.
2. Remove sheave from restrainer, install wire and
re-fasten sheave. Note: Be careful to not lose stain-
less steel sleeve when removing sheave. Make sure
forward side of restrainer is parallel to headstay.
Do not install upside down. See drawing on
reverse side. Bend cotter pin so clevis pin will not
fall out.
3. Position restrainer on mast so halyard is at a 7 to 10° angle to
headstay. See drawing on reverse side.
If necessary have a sailmaker cut down top of sail to create a 7 to 10° angle
between halyard and headstay.
With restrainer installed, halyard swivel will ride lower than installations with-
out restrainers. This is necessary to achieve correct halyard angle.
